Regulation of the process of social reproduction of rural territories under depopulation conditions
type: item
description: Background. The article is devoted to the study of the problem of social reproduction of rural territories under depopulation conditions complicated with consequences of the COVID-19 pandemic. The study also includes the effect of the special military operation on country’s rural border territories. According to authors, social reproduction is necessary to consider as self-regulated and regulated process of renewal of quantitative and qualitative resources of rural areas for stabilization of the rural socio-territorial community, overcoming of degradation processes and further sustainable growth. The aim of this article is to analyze modern reality regarding demographic processes taking place in rural territories and to identify the main directions in the regulation of the social reproduction process in rural areas. The paper has implemented the dispositions of rural residents regarding demographic potential and demographic trends, as well as the expert community in the regard of risks and threats to socio-demographic security of rural territories of the Central Black Earth Economic Region. It is noted that the statistics of Russian rural population’ demographic development clearly shows the trend of depopulation of these areas which is determined not only with a combination of demographic factors, including the demographic transition, but also, perhaps to a greater extent, by socio-political and economic conditions. Purpose. The objective of the present investigation is to study of the problem of social reproduction of rural territories under depopulation conditions complicated with consequences of the COVID-19 pandemic. Materials and methods. When considering the process of social reproduction of rural areas, we will rely on the concept of rural networks developed by a team of authors led by Dutch economist Frederick Van der J.D Ploeg. Dutch scientists have combined numerous theoretical concepts and ideas regarding rural development, rural networks, in their opini…

Assessment of anthropogenic load by the level of fluctuating asymmetry of Betula pendula leaves (using the example of the Don State Technical University training and experimental site)
type: item
description: Background. This study aimed to assess the level of anthropogenic stress on the territory of the Don State Technical University training and experimental site (Rassvet, Rostov Oblast) using the fluctuating asymmetry method of Betula pendula Roth. A comparative analysis of the integral index of fluctuating asymmetry was conducted between zones with different levels of expected impact (“Site 1” and “Site 3”) and a conventional background zone (“Roshcha”). The level of fluctuating asymmetry in the anthropogenic impact groups was significantly higher than in the background zone, and the overall environmental condition of the study area corresponded to the “alarm” category. The most stress-sensitive traits were the length of the second vein and the angle between the veins. The fluctuating asymmetry method has proven its effectiveness for bioindicating complex anthropogenic stress in urban ecosystems. Purpose. The aim of the study was to quantitatively assess the level of anthropogenic stress on the territory of the Don State Technical University training and experimental site by analyzing the fluctuating asymmetry of the leaves of Betula pendula Roth and identifying the most sensitive morphological features. Materials and methods. The study focused on Betula pendula Roth growing in anthropogenically altered habitats, with special attention to the fluctuating asymmetry of its leaf morphological traits in the leaf blade of Betula pendula as an indicator of developmental instability. A method for assessing fluctuating asymmetry of the leaf blade was employed. Standard biometric methods were used to measure five leaf blade traits, followed by calculation of the relative asymmetry value for each trait and the integral fluctuating asymmetry index for each leaf. Statistical data processing included descriptive statistics, testing for normality (Shapiro-Wilk test), and homogeneity of variance (Levene’s test). One-way analysis of variance (ANOVA) with Tukey’s post hoc test was us…

The effect of probiotic-enriched feed on aquaculture-biological parameters of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) during early ontogeny
type: item
description: Background. The issues of increasing productivity in various sectors of agriculture, especially the aquaculture sector, are currently a priority for many research teams in Russia and other countries. The production intensification inevitably leads to a decrease in the resistance of aquaculture objects, which makes them susceptible to various pathogenic agents, resulting in a decrease in overall production efficiency. The use of probiotics in the biotechnological farming cycle can reduce the negative effects of intensification. It has been repeatedly suggested that bacterial strains with probiotic properties, which were originally characteristic of the organism in question and its habitat, have the greatest effect on the fish body. In this paper, the effects of probiotic bacterial strains isolated from bottom sediments in fish habitats are considered. Purpose. The aim of the study was to study the effect of probiotics in the feed on the fish-breeding and biological parameters of trout Oncorhynchus mykiss (Walbaum, 1792) during the early ontogenesis. Materials and methods. The experimental site was an industrial-type fish hatchery located in the Rostov region. The object of the study was 100,000 species of O. mykiss rainbow trout larvae aged 29 days, which were randomly divided into 2 groups (control and experiment). The duration of the experiment was 30 days. The diet of the individuals included starter feeds for juvenile salmon with a grain size of 0.2 mm and a crude protein content of 58.0%. The experimental group received a probiotic supplement with 2 strains of the bacterium Bacillus subtilis (strains MT48 and MT74) as a part of the diet. The content of bacterial cells in the finished feed was 7.3·106 CFU/g. The valuation, during which the morphometric parameters of the fish were evaluated, was carried out 2 times during the experiment period: at the beginning and at the end. To assess the effectiveness of probiotic implementation in the diet, fish farming coeffi…

Modular robotic platform for an automated soil monitoring system
type: item
description: Background. The modular robotic platform is implemented using the “robot-constructor” principle. The basic platform includes standardized interfaces for connecting various modules – specialized chassis for different types of surfaces, manipulators for cargo handling, and sensor systems for navigation and environmental monitoring. This architecture allows the robotic platform to be quickly adapted to specific customer needs without the need to develop a completely new solution. The platform demonstrates particular practical value in agro-ecological monitoring, where the modular architecture allows for the rapid adaptation of sensor equipment for analyzing key soil parameters. Purpose. To present the architectural and functional design of a modular robotic platform implementing the “robot-constructor” principle and to justify its effectiveness as a basis for creating adaptive ground systems within the national aerospace infrastructure. Materials and methods. The development of a modular self-propelled robotic platform was carried out within the framework of system engineering: conceptual design → synthesis of architecture → selection of components → integration of subsystems → verification on a physical layout. The design is based on a lightweight and rigid metal frame that allows quick replacement of modules (chassis, manipulators, sensors). For work in the agricultural sector, it is possible to switch from a wheeled to a tracked base. Localization and orientation are implemented using visual odometry and simplified SLAM (ORB-SLAM2 light) for building 2D maps. Motion control is a multi-contour PID controller: the external contour corrects the deviation from the trajectory according to the video (P+D), the internal one stabilizes the speed according to the encoder data (I-component). The software platform is ROS 2 Humble (Python 3.10). Key nodes: - vision_node – marker recognition (OpenCV + TensorFlow Lite); - navigation_node – route construction and correction (RRT);…

Effect of TGF and VEGF proteins on prenatal diseases of calves: Correlation analysis under complicated pregnancy conditions in cows
type: item
description: Background. The study of the role of transforming growth factor (TGF) and vascular endothelial growth factor (VEGF) in the development of prenatal pathologies in calves, especially in the context of complicated pregnancy in cows, is relevant due to the high incidence of morbidity and mortality in newborn young animals, which significantly reduces the economic efficiency of the livestock industry. The study is based on analyzing placental tissue collected immediately after calving to identify relationships between the levels of these proteins and the incidence of pathologies in newborn calves. Changes in TGF and VEGF concentrations can serve as predictors of feto- and uteroplacental insufficiency, which in turn negatively affects the health of calves. Correlation analysis revealed statistically significant relationships between TGF and VEGF levels and clinical disease manifestations, highlighting their role in prenatal disorder pathogenesis. These studies underscore the importance of monitoring TGF and VEGF levels in veterinary practice, potentially enabling early risk identification and the development of effective disease prevention strategies in young animals. Purpose. The objective of the present study is to develop new methods for predicting prenatal diseases in calves based on the correlation analysis of TGF and VEGF protein levels. Materials and methods. At the SPC “Plemzavod Vtoraya Pyatiletka”, in the period from 2023 to 2024, a correlation analysis of the proteins TGF and VEGF in the context of complicated pregnancy was carried out. For the experiment, 200 dry first-calf heifers aged 24 to 48 months were randomly selected. The animals were divided into two groups: Group A included 100 cows with a physiological pregnancy and uncomplicated births, and Group B consisted of 100 animals with complicated pregnancy, accompanied by feto- and uteroplacental insufficiency. The distribution of livestock into groups was carried out on the basis of anamnesis data and cl…

The influence of deuterium-depleted water Larsen D100 on seed germination parameters in cereal, oilseed, and legume crops
type: item
description: Background. The study aimed to investigate the species-specific effects of deuterium-depleted water (Larsen D100, <100 ppm D) on seed germination and early seedling growth parameters of key agricultural crops (barley, wheat, rapeseed, and lentil) under controlled in vitro conditions. Seeds were germinated in Petri dishes on a fabric material moistened with either distilled water (control) or Larsen D100. The experiment was set up in a completely randomized design (CRD) with several biological replications. After 10 days, the following key parameters were assessed: germination rate, seedling length, and fresh biomass. Data were statistically processed using Student’s t-test or the Mann-Whitney U-test (p<0.05). Treatment with deuterium-depleted water had a pronounced and species-specific influence. A significant stimulatory effect was recorded in barley: germination increased by 20%, seedling length by 72%, and biomass by 17% compared to the control. Lentil showed a sharp increase in length (222%) and biomass (64%) of seedlings, although germination rate remained unchanged. In contrast, rapeseed exhibited inhibition of biomass accumulation (a 38% reduction), while wheat parameters did not change. Deuterium-depleted water acts as a powerful metabolic modulator, but its effects are strictly species-specific-ranging from significant stimulation to inhibition. The obtained data highlight the potential for its use in pre-sowing seed treatment for crops such as barley and lentil but strongly caution against universal application without mandatory prior species and cultivar testing. The observed effects are associated with isotope-mediated changes in the kinetics of key enzymatic and osmotic processes in the early stages of plant development. Purpose. Of the study was to evaluate the effect of deuterium-depleted water (Larsen D100) on germination efficiency (germination rate) and initial growth vigor (length and fresh weight) of seedlings in four economically important speci…

Influence of stress factors on crustacean gene expression
type: item
description: Background. This review systematizes current scientific data on the influence of abiotic (pH, temperature, hypoxia, ammonia, nitrite) and biotic (viral and bacterial infections) stress factors on gene expression in crustaceans of the order Decapoda. Molecular responses affecting key functional groups of genes associated with immunity, osmoregulation, antioxidant defense, chitin metabolism, and cellular homeostasis are analyzed. Stress-induced changes in gene expression are complex, tissue-specific, and time-dependent, representing key adaptive mechanisms. The results of this analysis have important practical implications for aquaculture, opening up prospects for identifying molecular markers of stress resistance and developing strategies for optimizing the maintenance conditions of commercially important species. Purpose. This review aims to systematize and analyze current scientific data on the influence of abiotic (such as pH, temperature, hypoxia, ammonia, nitrites) and biotic (viral and bacterial infections) stress factors on expression of genes associated with immunity, osmoregulation, antioxidant defense, chitin metabolism and cellular homeostasis in crustaceans of the order Decapoda. Materials and methods. The research was conducted in the scientific research laboratory “Center of Agrobiotechnology” of the Don State Technical University in 2024-2025. Results. Complex changes in the expression of key genes regulating immunity, osmoregulation, antioxidant protection, chitin metabolism, and cellular homeostasis have been identified. It has been shown that these tissue-specific and time-dependent changes in expression are the central mechanism of the adaptive response to stress. Conclusion. An analysis of current scientific data has allowed us to systematize information on the influence of abiotic and biotic stress factors on gene expression in crustaceans, particularly in members of the order Decapoda. It has been established that changes in key environmental pa…

Increase the yield of industrial crops due to bionutrients
type: item
description: Background. The article is devoted to the search for effective ways of a reasonable approach to the chemicalization of agriculture, which will increase crop yields without increasing the doses of applied mineral fertilizers and pesticides. The materials of the analysis and generalization of the results of long-term studies of bionutrients safe for humans and animals synthesized using the triethanolammonium salt of orthocresoxyacetic acid and 1-chloromethylsilatran are presented. The conducted studies have shown that it is possible to achieve high yields of industrial crops that do not depend on the constantly increasing values of mineral fertilizers and pesticides introduced into the soil. An increase in sugar beet yield of up to 20% is recorded when processing seeds and fruiting plants with bionutrients. This is due to an increase in germination energy, and, as a result, seed germination improves. At the same time, the sugar content in plants increases by 0.7 ...1% without the use of additional doses of mineral fertilizers. A similar effect was obtained on sunflower: the yield increase was 18...20%. the weight of seeds from one basket and the weight of 1000 seeds and their oil content increased. Bionutrients restrained the spread of fungal diseases, which makes it possible to reduce or eliminate the use of pesticides. Thus, silatrans and other organosilicon compounds can become important components of agricultural technologies that do not harm the ecosystem, but can improve metabolic processes in plant organisms, increase the efficiency of using nutrients from mineral fertilizers and reducedependence on pesticides used in agriculture. Purpose. Purpose of the present study is to increase the yield of industrial crops using bionutrients. Materials and methods. Let’s consider the effectiveness of the use of 1-chloromethylsilatran and triethanolammonium salt of orthocresoxyacetic acid with auxin activity as independent bionutrients and in combination with each other.

Accelerated development of rice populations using anther culture in vitro method
type: item
description: Background. Inclusion of doubled haploids in the breeding process allows increasing the speed and reliability of selection of desired forms with smaller population volumes. To stabilize the genotype, anthers of hybrid combinations of F2, F3, F4 and F5 generations, developed in crossings of white-grained samples with traits of high nutritional value of grain, and anthers of combinations of F4 generation from crossings of varieties contrasting in pericarp color and amylose content, were introduced into the culture. The responsiveness to gamete technologies was studied in 21 hybrid combinations. New genetically stable material (DH - doubled haploids) was developed. Phenotyping was carried out in conditions of a vegetation experiment for economic and biological traits and elements of plant productivity in four populations, which included 45 DH lines. Variability was noted in a number of traits within the DH line populations. Based on the results of the biometric analysis of the regenerated populations, 6 sources with a “1000 grain mass” of more than 30 grams were identified. The study was carried out with the financial support of the Kuban Science Foundation and the Russian Science Foundation within the framework of the scientific project No. 25-16-20103 “Application of the genomic approach in rice breeding for high technological grain quality” Purpose. To study the response of hybrids obtained from crossing contrasting rice samples to in vitro pollen culture, to accelerate the creation of DH line populations based on the studied genotypes, and to phenotype them. Materials and methods. The research was conducted at the Laboratory of Biotechnology and Molecular Biology at the Federal Research Center for Rice, using the culture of isolated anthers in vitro according to the generally accepted method of R.G. Butenko (1990). Results. The genetic determinism of the “regeneration” trait in the donor plants used in the crossbreeding was noted. The genotypes of the crossbreeding…

Reproductive qualities of boars in the assessment of adaptive capabilities when using introductory crossbreeding of different variants
type: item
description: Background. The article deals with the study of the reproductive performance of breeding boars of Poltava meat breed when using different variants of introductory crossbreeding. At the same time, the objectives of using introductory crossbreeding determine the dynamics of changes. By introductory crossing in the breed new genotypes were created with Finnish Landrace pigs (in order to improve productive qualities) and fast-ripening meat pigs (in order to increase the adaptive capacity of animals to natural and climatic conditions of the farm). To conduct research we formed four groups according to the principle of pair-analogs: Group I – boars descendants of introductory crossbreeding, with a share of blood of the fast-ripening meat breed 25%, Group II – boars descendants of introductory crossbreeding, with a share of blood of the Finnish Landrace breed 25%, Group III – boars descendants of introductory crossbreeding, with a share of blood of the fast-ripening meat breed 50%, Group IV – boars descendants of introductory crossbreeding, with a share of blood of the Finnish Landrace breed 50%. We evaluated boar development indicators (live weight, body length, age at 100 kg live weight, thickness of the bailiffs follower) and indicators characterizing reproductive capacity (number of inseminated and farrowed breeding sows, fertilizing capacity of the boar, multiple fertility of farrowed breeding sows, weight of one piglet at weaning at 45 days). Infusion of Finnish Landrace blood in order to improve meat qualities leads in boars of Poltava meat breed to a violation of adaptive capabilities, manifested in an increase in the age of achieving a live weight of 100 kg and a decrease in reproductive performance, not actively involved in the selection process. Increasing the level of bloodlines of breeding boars up to 50% for Finnish Landrace breed is not reasonable in these natural and climatic conditions and will require additional costs to improve efficiency. The infusion o…

Rheology of heterogeneous food systems on the basis of biopolymers
type: item
description: Background. Problem of transformation of complex food systems is incompletely solved. In the framework of this problem, the incompletely solved problem of three-dimensional structure of proteids, including collagen, takes place. In this regard, the authors propose solutions of this problem basing on the study of structural rheological properties of polydisperse heterogeneous systems on the basis of natural intentionally modified biopolymers, incl. their microstructures. The rotational viscometry and analysis of images obtained with the scanning electron microscopy have been used as test methods. As a result, dependencies of the dynamic viscosity from the speed rate of the shear deformation have been obtained. They have shown relatively regular changes of the viscosity indicators. Data from the electronic microscopy let us to diagnose the structure of raw material and specially prepared semi-finished product, dominated by biopolymers, for further processing in industries. Purpose. Taking into account the problem urgency, introduced in the first part of the article, we have stated the characteristic dependence between the dynamic viscosity of the typical polymer solution – alginate (semi-finished product for artificial caviar production) and shear deformation speed rate. Materials and methods. The directions of solving the issue of microstructure and properties of biopolymers from different groups are actualized. In particular, biopolymers of alginate type and proteins from the collagen group have been investigated. The peculiarities of the denaturation of native proteins cause the necessity of their further study (analysis of the initial architectonics of molecules, their changes under chemical and/or thermal influences) in the preparation of raw materials for the product manufacturing, feeds, etc. The general orientation of process organization is to avoid denaturation transformations. However, treatment in media with the adjustable pH level is expected. The example…

Problems of introducing innovations into agricultural production
type: item
description: Background. The article solves the problems of introducing the latest technologies in agriculture. Because manual labor is very difficult to switch to electronic technologies and technologies in general. Using a combine harvester instead of a plow, instead of manually milking a cow, a special device, entering data on the results of work into an electronic journal and calculations in an unnatural, but non-cash form - this is the future of agriculture largest agricultural powers. The article shows the problems of modern agricultural enterprises and outlines ways to solve them based on the current state of science, technology, legislation, economic and social state of modern society. The difficulties in the path of the agro-industrial sector are quite natural and solvable with a careful approach and digitalization. Purpose. Agricultural work has historically been directly related to the use of manual labor. As technology developed, societies and states began to use other technologies and manual labor was gradually replaced by machines and automatic devices. However, the transition from manual to machine labor turned out to be very long and difficult. Mainly. Because of the reluctance to abandon the use of manual labor. When working on the land, the labor of people living on it was used. Therefore, the refusal in favor of machine labor was perceived as recognizing the peasant as unnecessary and superfluous. The process sometimes took place gradually, sometimes in leaps and bounds. It led to riots, revolutions, the overthrow of the system, physical violence and threats. But time moves forward and technical progress can no longer cancel anything. Materials and methods. To study introduction of innovations in agricultural production, the following methods are used. The method of materialist dialectics is the study of dynamics, development, movement from one state to another. The method of scientific abstraction is abstraction from the unimportant and random in order to hig…

Bacteriocins for agriculture and aquaculture
type: item
description: Background. The aggravation of the problem of antimicrobial resistance caused by the irrational use of antibiotics in agriculture and aquaculture necessitates the search for sustainable and safe alternatives. Bacteriocins are ribosomally synthesized antimicrobial peptides of bacterial origin. A class of natural compounds for combating resistant pathogens with minimal environmental impact. This review explores the complex potential of using bacteriocins as an alternative to antibiotics. A detailed analysis of the structural diversity, classification approaches, and established mechanisms of antimicrobial action was carried out, including disruption of cell membrane integrity, inhibition of cell wall synthesis, and inhibition of nucleic acid and protein production. Key bacteriocin-producing genera (Bacillus, Streptomyces, and Pseudomonas) and their biologically active metabolites have been identified. The analysis of bacteriocins’ use in agriculture, in particular their role as agents of biocontrol of phytopathogens, plant growth promoters, as well as means of improving the health and productivity of farm animals and birds. Their potential in aquaculture for disease control (directed against pathogens such as Vibrio spp., Aeromonas spp., Yersinia ruckeri), water quality improvement, and feed conservation is considered, which helps reduce dependence on the preventive use of antibiotics. Despite significant achievements, challenges remain related to in vivo efficacy assessment, development of delivery systems, the possibility of resistance development, and regulatory aspects. Addressing these issues is a key condition for realizing the potential of bacteriocins as environmentally sound tools for ensuring food security and sustainable development of terrestrial and aquaculture systems. Purpose. The aim of this review is to comprehensively analyze the potential of bacteriocins as a sustainable alternative to antibiotics in agriculture and aquaculture. This involves summar…

Analysis of the effectiveness of coagulants in water treatment
type: item
description: Background. Obtaining water suitable for domestic and industrial needs and safe for the consumer is the main task of water treatment. The search for ways to improve the coagulation process and methods that allow its intensification is currently still relevant. The article presents the results of studies of coagulants at various combinations and doses in laboratory conditions. Irtysh river water intended for drinking purposes is considered as an object of research. The efficiency of using different coagulants that allow to remove pollutants such as heavy metals, organic compounds, microbiological pollutants, etc. in a more qualitative way has been studied. This is especially important for the treatment of water from surface sources, which is often characterized by a high content of impurities. Experimental studies in the shop of operation of water supply networks and facilities of Rosvodokanal Omsk were conducted with the following coagulants “Brilliant-18”, “Bopak-E”, “OHA”, “Aqua-aurat 30” and “ASA” in combination with flocculant FL 4540PWG. Coagulants were tested in the spring flood period at the source water temperature of 6-8°C. On the source water of the Irtysh River the best results were shown by coagulants such as “Bopak-E”, “OHA” and “Aqua-aurat 30”. The optimal dose for the most effective coagulants is Dk=1.5 mg/l (by Al2O3) when combined with flocculant with Df=0.1-0.13 mg/l. Coagulant “Aqua-aurate 30” shows better flaking, sedimentation and clarification, and accordingly better performance on water turbidity. To confirm the results of laboratory tests and select the most effective reagent, it is recommended to conduct production tests of coagulant “Aqua-aurat 30”. Purpose. The main objectives of the research are to test the used reagents in laboratory conditions and compare their efficiency in different seasons of the year, as well as to improve the water treatment process by introducing new reagents.

Microbiological study of wounds and large intestine of sturgeons using β-cyclodextrin complex with levofloxacin
type: item
description: Background. The research laboratory Progressive biotechnologies in aquaculture of the Saratov State University of Genetics, Biotechnology and Engineering named after N.I. Vavilov studied the effect of complexes of ß-cyclodextrin on the healing of skin wounds in hybrid sturgeon fish. The total microbial count of sturgeon cut wounds was determined using the culture method and the composition of the microflora of the fish colon using the qPCR method under the influence of the ß-cyclodextrin complex. This complex was ß- cyclodextrin with levofloxacin included in a chitosan shell. The complex was adsorbed on the surface of the feed that the sturgeons received daily. Changes in the total microbial count demonstrate the nature of the inflammatory process and the effectiveness of the use of therapeutic drugs. The study of the colon microbiota also demonstrates the result of using these complexes in fish. It was found that the use of antibacterial complexes of ß-cyclodextrins with chitosan on sturgeons leads to a significant decrease in the total microbial count of the wound surface. The highest antimicrobial activity was established for the chitosan-ß-cyclodextrin complex with 20 and 15% levofloxacin content. The presence of bacteroides, eubacteria, clostridia, peptostreptocci, enterobacteria, lactobacilli and staphylococci were determined in the composition of the normal flora. At the same time, by the end of the experiment, the microbiome of the large intestine of fish is characterized by the restoration of the number of lactic acid bacteria. The research results can be used in aquaculture in the process of fish cultivation in the treatment of injuries to the outer coverings received during transportation and sorting. Purpose. Reproduction and cultivation of fish in aquaculture is inevitably associated with trauma to the skin of fish, infection with saprophytic, opportunistic and pathogenic microorganisms during transportation, sorting, dense planting, and transition to n…

Comprehensive monitoring and prediction of prenatal disorders in calves born from cows with complicated pregnancy
type: item
description: Background. In recent years, there has been a growing interest in modern methods for diagnosing feto- and uteroplacental insufficiency in cattle, which is due to the need to improve the reproductive health of animals and the quality of newborn offspring. The use of echographic and electrocardiographic methods makes it possible not only to assess in detail the condition of the fetus and uterus, but also to predict the course of pregnancy, which is crucial for preventing adverse outcomes. Particular attention is paid to hypoxic myocardial damage in cows, which is identified as one of the leading causes of adverse reproductive outcomes. This condition is associated with metabolic disorders, which in turn leads to the development of pathological metabolic acidosis. Acidosis has a depressing effect on enzymatic processes in the fetus, which can cause serious disturbances in its development and, as a result, negatively affect the health of newborn calves. The introduction of comprehensive monitoring, including regular ultrasound examinations and electrocardiographic monitoring, allows for timely detection of predisposition to feto- and uteroplacental insufficiency. This, in turn, creates the opportunity for early intervention and correction of identified disorders, which contributes to improving pregnancy outcomes and reducing the risk of prenatal pathologies. Purpose. The objective of the present study is to develop methods for comprehensive monitoring in order to predict prenatal disorders in calves born from cows with complicated pregnancy. Materials and methods. At the SPK Plemzavod Vtoraya Pyatiletka, from 2023 to 2024, the main studies on monitoring and predicting prenatal disorders in calves born to cows with feto- and uteroplacental insufficiency were carried out. As an object of research, 200 heads of dry first-calf cows aged 24 to 48 months were selected by the blind sampling method. Thus, the first group (A) consisted of 100 animals with uncomplicated pregnancy…

type: item
description: Background. In the era of digitalization, maintaining resilient security systems in agro-industrial enterprises is crucial. This paper examines approaches to developing intelligent models aimed at assessing and predicting the resilience of organizational and technical systems based on the analysis of interrelated risk factors. Cognitive and fuzzy modeling approaches are applied as methodological tools to formalize expert knowledge and support managerial decision-making. A methodology for constructing an integrated resilience indicator that takes into account both external and internal dynamics is proposed. Scenario analysis demonstrates the potential of intelligent algorithms to model critical situations and to select optimal response measures. The developed models can be applied to strengthen infrastructure protection strategies, enhance information and physical security, and ensure the sustainable operation of enterprises in uncertain environments. The aim of the study is to develop and verify a model based on fuzzy cognitive maps (FCMs) for the mathematical assessment of the resilience of agricultural enterprise security systems. The work aims to integrate expert knowledge, scenario modeling, and dynamic visualization of system behavior under changing external and internal factors. Materials and methods. The methodological framework of the study is based on cognitive and fuzzy modeling, simulation, and machine learning. FCMs are used as tools, accounting for uncertainty, the subjectivity of expert assessments, and nonlinear relationships between factors. Logistic Regression, Random Forest, and XGBoost algorithms, implemented in Python, were used for computational experiments. The analysis was conducted using the IGLA package for constructing cognitive models and assessing impact scenarios. Results. An intelligent security system resilience model was developed, incorporating five key concepts: financial resilience, human resources, technological reliability, infor…

Influence of polishing degree on technological traits of grain of different rice varieties
type: item
description: Background. The quality of rice products, their physical properties and nutritional value depend on the degree of grain processing, including its polishing, which removes the surface shells and the germ. The task of the work is to assess the effect of the degree of grain polishing of Russian-bred rice varieties with different grain sizes and shapes on the physical (technological) traits of the grain. Purpose. The goal of the study was to assess the influence of the grain polishing degree of Russian-bred rice varieties with different grain sizes and shapes on the physical (technological) traits of the grain. Materials and methods. The research material included the following varieties: Favorit, Veles, Trio, Regul 2, Forsazh, Strombus, Prestige, Vector, most of which are approved for use. The set of parameters for assessing grain quality included the following indicators: grain size, vitreousity, grain fracturing, total milling yield, head rice content, and bran yield during polishing. The duration of polishing was 50, 90, and 120 seconds. Results. The mass of 1000 absolutely dry grains was in the range of 25.6–26.6 g in the group of medium-weight varieties and 28.4–33.1 g in the group of large-grain rice varieties. In the group of large-grain varieties, the varieties Forsazh and Strombus were the most resistant to intensive polishing, the varieties Prestige and Regul 2 were the least resistant; in the group of medium-weight varieties, the corresponding indicators of the head rice content were significantly lower.

type: item
description: Background. In marker-assisted rice breeding, the accelerated development of varieties with superior grain quality traits through advanced biotechnological approaches requires the generation of segregating rice populations followed by phenotyping of genotypes for traits of interest. These segregating populations are used to identify genetic loci (QTLs) associated with complex traits, including rice grain quality, based on phenotypic data. Purpose. The goal of the work was to evaluate experimental BC3 populations of rice based on physical characteristics of grain: size, vitreousity, fracturing, in order to carry out work on targeted selection based on phenotyping and genotyping data of promising plants - prototypes of varieties with specified traits in marker-assisted rice breeding. Materials and methods. The study involved hybrids of 15 combinations of parental forms. The seeds were sown in vessels on the vegetation site of FSBSI Federal Scientific Rice Centre, Pryanishnikov’s mixture was used as the main fertilizer; as they ripened, the seeds were harvested manually. High-tech methods of phenotyping the breeding material were used to conduct the research. The grain size was estimated by the mass of 1000 absolutely dry grains using a moisture analyzer, an air-heat unit, and an automatic seed counter; the vitreousity and grain fracturing were estimated in transmitted light using a diaphanoscope. Results. Genotypes were differentiated and distributed into groups for each trait.

During the growth and development of young cattle, there is a significant association between functional changes in the body and housing conditions, influencing the regulation of immune responses and metabolic processes. In calves kept in natural conditions, the activity of natural immunity regulators prevails, contributing to the optimisation of growth and development processes. At the same time, in young animals exposed to stressful conditions associated with intensive housing methods, a decrease in the activity of these regulators is recorded, which can negatively affect their health and adaptability. Activation of neurohumoral mechanisms, including the influence of the hypothalamic-pituitary system, plays a key role in the regulation of metabolic processes and the immune response in young animals. In calves under stress, an increase in the level of proinflammatory cytokines is noted, which indicates a violation of the physiological balance in the cytokine network. Conversely, in calves kept in more favorable (natural) conditions, a more balanced ratio between pro- and anti-inflammatory cytokines is observed, contributing to the maintenance of homeostasis and improved adaptive responses. Purpose. The main objective of the present research is to find out the correlation between cardiac rhythm parameters and cytokine profile levels in young cattle during early neonatal ontogenesis. Materials and methods. To study the nature of the correlation between the parameters of the heart rate and the levels of cytokines in young cattle in early neonatal ontogenesis, 50 one-day-old calves aged 5 days were randomly selected at the premises of Chapaevskoye SP LLC. In the first experimental group, after calving, the newborn calf underwent a primary veterinary examination, after which it was left in a group with its mother, simulating natural conditions for the entire duration of the experiment. In the second experimental group, calves were managed according to indust…

Feeding specifics of the Australian red claw crayfish Cherax quadricarinatus (von Martens, 1868) in aquaculture
type: item
description: Background. The selection of optimal feed formulations is a primary factor determining the efficiency and sustainability of aquaculture. The Australian Red Claw Crayfish, Cherax quadricarinatus (von Martens, 1868), known for its high growth rates and tolerance to water quality parameters, is a popular aquaculture species worldwide. However, the development of specialized feeds for this species remains insufficiently addressed. In practice, prepared feeds for other crustaceans or for sturgeon are commonly used for its cultivation. In natural habitats, the diet of this crayfish consists primarily of macrophytes (up to 87.5%) and detritus (42.8%), with the proportion of the plant component increasing with body size. The omnivorous feeding type creates opportunities for finding cheaper protein sources compared to fishmeal. Analysis of scientific research has shown that black soldier fly larvae and yellow mealworm can be used as alternatives to fishmeal in feeds for the Australian crayfish. Among plant-based raw materials, soybean, rapeseed, and peanut meal are unsuitable components. The specific feeding behavior of the Red Claw Crayfish necessitates sufficient stabilization and binding of feed pellets. Furthermore, the shape of the feed pellets must be considered, with the prism shape being the most preferable. Developing feed formulations that account for the biological specifics of the Red Claw Crayfish will enhance the efficiency of its aquaculture and reduce costs for farmers. Purpose. To identify the main dietary characteristics and nutritional requirements of the Australian red claw crayfish Cherax quadricarinatus in order to develop feed formulations that ensure high farming efficiency and economic sustainability in aquaculture. Materials and methods. A comparative – analytical approach was applied in this study. The information base was formed through the analysis of more than 150 scientific publications from both domestic and international sources. Literature s…

The influence of heat treatment regimes on the mechanical properties of unsaturated polyester resin composites reinforced with fiberglass for agricultural machinery working parts
type: item
description: Background. In modern agriculture, enhancing the durability and efficiency of machinery components, such as soil tiller blades, is crucial for improving productivity and sustainability. In this context, the study of advanced materials like glass fiber-reinforced unsaturated polyesters presents a relevant challenge. Purpose. The aim of this research was to experimentally investigate the possibility of improving the properties of this composite material for the production of agricultural machinery parts. Materials and Methods. For the study, samples were made from glass fiber-reinforced unsaturated polyester with various proportions of added components. The samples were divided into two groups: one group underwent thermal treatment, while the other remained untreated. Mechanical property testing was conducted using standard tensile tests to determine the values of tensile strength. Observations were also made regarding changes in mechanical properties under prolonged heat exposure. Results. The results showed that samples with optimized proportions of added components, without direct thermal treatment, exhibited lower tensile strength values compared to samples that underwent thermal treatment. However, with prolonged application of heat over a relatively long period, the strength values began to decrease significantly. This indicates that extended heating leads to increased brittleness of the polyester composition and enhances reactions occurring within the mixture, negatively affecting the strength properties of the material under investigation. Conclusion. The obtained data indicate a complex relationship between thermal treatment and the strength characteristics of the material. While thermal treatment may initially improve properties, prolonged heat exposure can lead to structural degradation and reduced strength. These results highlight the importance of optimizing technological processes in the production of soil tiller bladeto achieve a balance between enhanci…

Use of biotechnological methods for accelerated improvement of Kalmyk cattle
type: item
description: Background. The reduction in the number of some domestic breeds raises concerns among livestock experts. One of the reasons for the reduction in the number of livestock is the lack of purebred bulls, which are able to preserve the breed. Kalmyk breed of cattle is the only ancient aboriginal domestic breed of meat direction. It is kept on year-round pasture keeping, thus on productivity indicators it is not inferior to foreign breeds of meat direction. In this connection preservation and improvement of the gene pool of this breed is important. Kalmyk cattle breed is one of the few indigenous Russian breeds that still possesses unique genetics. Currently, the breed needs to be restored and protected. In order to increase the number and improve the breed qualities of Kalmyk animals, selection is necessary, which should be based on reliable information about the origin of animals and identification of candidate genes marking productive and reproductive qualities. Restoration and improvement of breed qualities of Kalmyk cattle is possible only under the condition of accelerated reproduction of purebred genotyped stock with the use of biotechnological methods in reproduction. The analysis of complex evaluation of animals showed the variability of live weight of bulls-producers and cows in different periods of growth, from 20, 22 kg at birth to 320, 380 kg at 15 months. Evaluation of the genetic structure of the Kalmyk population for meat productivity genes CAPN1, TG5, GH, revealed a high level of homozygous individuals with desirable genotypes, more than 40%. The average level of heterozygous individuals is 30%. The results obtained on the genetic structure of Kalmyk cattle in the Republic of Kalmykia demonstrate a moderate level of genetic diversity and suggest the possibility of restoring a “pure” gene pool. The selected schemes of hormonal polyovulation for the arid breed revealed a high percentage of fertilization (81%) and 92.3% of donor cows responding with superovu…

Immunological status of highly productive cows with comorbid obstetric-gynecological and orthopedic pathology
type: item
description: Background. Research and clinical observation confirm a significant correlation between postpartum metabolic/obstetric diseases and the development of orthopedic pathology in highly productive cows. In particular, a study supported by the Russian Science Foundation (grant No. 24-26-00172) revealed a clear relationship between the development of purulent-necrotic lesions of the hooves and the occurrence of postpartum endometritis in high-yielding cows. In this study, the following groups of animals were formed by randomization: group 1 (n=28): cows with acute purulent-catarrhal postpartum endometritis; group 2 (n=25): animals with purulent-necrotic lesions of the hooves; group 3 (n=27): cows with a comorbid course of both pathologies; and the control group (n=23): clinically healthy animals. All individuals selected for the study had their jugular venous blood collected on an empty stomach into sterile tubes for subsequent immunological analysis. It was found that the comorbid course of these pathologies is significantly more severe than each of the diseases in isolation. This is evidenced by the immunological screening we conducted. In this regard, when an animal has multiple pathologies, an individual approach is necessary, which dictates the need for a comprehensive study of the clinical course of the main, concomitant, and even previous diseases, their comprehensive diagnosis, and rational treatment. Purpose. The purpose of the present paper is to study the immunological status of highly productive cows with comorbid obstetric-gynecological and orthopedic pathology. Materials and methods. To assess the dynamics of the clinical manifestation of hoof diseases, an orthopedic examination was conducted on a monthly basis throughout the year. During this examination, the following were evaluated: the degree and nature of hoof deformities; the intensity of corneal destruction; the presence of specific lesions such as pockets, delamination, and cracks; and the position o…

Traction characteristics of tires of various designs for the complete set of mobile propulsion devices of the fifth traction class
type: item
description: Background. Tire properties are the main factors determining traction and agricultural technological performance of wheeled mobile energy vehicles. Purpose. The purpose of the research is to study the traction indicator efficiency of large-sized tires of various designs for equipping the running system of mobile power equipment of the fifth traction class. Materials and methods. Traction efficiency, as a universal indicator of the operation efficiency of a wheeled mobile energy machine, is largely determined by the pneumatic tire design of a running system. Therefore, serial tires 30.5R-32 and 33R-32, tires with optimized shell reinforcement 30.5R-32M and 33R-32M, and tires of experimental (diagonal-parallel) design 33DP-32 were used as objects of research. The research of tires designed for tractors’ driving wheels of the fifth traction class, in order to establish their traction and energy parameters, was carried out experimentally by testing them on a specially manufactured tire test bench. Traction properties tests of tires (at various air pressures in them) were carried out on different supporting bases: concrete, stubble of grain ears, and a field for sowing. Results’ confirmation was obtained during traction tests of the K-701M tractor when its running system was equipped with tested tires. Results. As a result of the traction tests carried out on a tractor of the fifth traction class (K-701M), the undoubted advantage of installing tires with optimal internal reinforcement parameters on its driving wheels over equipping them with mass-produced tires was established. All tires tested on a concrete base showed almost the same traction characteristics, but still the 30.5R-32M, 33R-32M and 33DP-32 tires had slightly higher values. On stubble and in the field for sowing, the 30.5R-32M, 33R-32M and 33DP-32 tires showed a higher traction efficiency of 0.03 or more due to a decrease in slipping by 5...16% compared to the production ones. It should be noted that the 3…

type: item
description: Background. This article discusses the problem of soil degradation from flooding and waterlogging. The analysis of the influence of these factors on the quality of land resources and agricultural productivity is given. As a solution, it is proposed to use digital surface modeling and other methods aimed at preventing erosion and improving soil condition. The article may be useful for scientists and specialists in the field of land reclamation and agronomy Purpose. Objective of the study to explore numerical modeling in the study of agricultural land degradation processes. Materials and methods. The research was conducted in the Dinsky district of the Krasnodar Territory, which belongs to the steppe zone. This area is characterized by significant humidification (from moderate to severe), relatively warm winters, short spring, hot summers, and long warm autumn. The annual rainfall in recent decades has increased to 643 mm, including 370 mm for the warm period (April – October) and 273 mm for the cold period (November – March). Results. A feature of the territory has been determined, which is weak slopes and depressions of the terrain, in which even small obstacles to surface and ground runoff in wet years can lead to waterlogging of soils. Closed relief depressions (saucers) were formed due to subsidence of soils under the influence of natural moisture. Due to the high porosity and significant carbonate content, loess-like rocks of the irrigation site are predisposed to subsidence phenomena that occur during irrigation or during waterlogging of rocks. The territory is in the initial stage of degradation caused by flooding and waterlogging of the land. Land degradation is caused by natural and anthropogenic factors, where anthropogenic factors are more strongly influenced. Conclusion. For intensive use of the studied territory (which is represented by meadow-chernozem leached weakly developed soils) in agricultural production, it is necessary to: carry out reclamation …

Immunomodulatory feed additives for farm animals and fish
type: item
description: Background. Modern applied biotechnology is focused on the development and implementation of fundamentally new multifunctional feed additives in a complex form. Currently, new approaches to the maintenance of farm animals and aquaculture objects under the influence of environmental factors are being sought, based on the use of biologically active additives. Intensive antibiotic therapy has become one of the reasons for the disruption of normal bacteriocenosis and a decrease in the immunobiological reactivity of animals and fish, the emergence of resistant strains of pathogens, which reduces the therapeutic effect of antibacterial drugs. The use of antibiotics leads to the accumulation of microorganisms with complex antibiotic resistance in the environment, their entry into natural water bodies is almost impossible. One of the promising ways to solve these problems is the use of feed additives with immunomodulatory action. The article examines existing feed additives with biological activity, provides generalized literature data on the use of biological additives in animal husbandry and aquaculture. Purpose. The objective of the present study is to investigate impact of immunomodulatory feed additives on farm animals and fish. Materials and methods. Feeds play a crucial role in the diet of farm animals and fish, as they must contain all the necessary nutrients, vitamins and minerals to ensure healthy growth and development of animals and aquaculture objects. Such preparations as probiotics (including symbiotics and metabiotics), prebiotics, and synbiotics, which are actively used in feed production, meet these requirements. In 1995, Gibson and Robertfroy introduced the concepts that should be classified as prebiotics and found that these components should be: 1) a selective component that promotes the metabolic activity or growth of one or more beneficial bacteria; 2) capable of altering the microbiota towards a healthy state; 3) capable of exerting a systemic or lum…

Cleaning method of working volumes of hydraulic cylinders of agricultural machines without preliminary dismantling
type: item
description: Background. More and more often lifting equipment is equipped with a hydraulic drive, which allows to develop the highest tractive force. However, this type of drive is prone to a reduction in the speed of the mechanism due to possible clogging of the working fluid. The performance of the hydraulic system directly depends on the cleanliness of the working fluid, which is operated in the equipment or machine. Dirt, the presence of air, as well as the presence of metal particles formed as a result of rubbing parts, all this negatively affects the service life and reliability of the hydraulic system. The paper describes a bench method of cleaning the working volume of the hydraulic cylinder without preliminary dismantling. The principal hydraulic scheme with a detailed description of the washing system operation is offered. The possibility of dispersing the flushing fluid flow by air bubbles is described. Purpose. The purpose of the research is a method of cleaning the working volumes of hydraulic cylinders of agricultural machines without preliminary dismantling Materials and methods. In most cases, the hydraulic system is flushed with the help of special stands. The flushing stand itself is a rather complex system of interaction of hydraulic units The design feature of the developed unit is the pressurized supply of a gas-liquid mixture. It consists of air bubbles and washing liquid. For the formation of air bubbles in the liquid a cavitator is installed.

title: Evaluation of fish-breeding parameters of yearlings of the F1 hybrid Acipenser gueldenstaedtii Brandt, 1833 × Acipenser baerii Brandt, 1869 with short-term introduction of probiotics of different action spectrum into the diet
description: Background. Under the conditions of the global shortage of accessible animal proteins, the task to develop the effective strategy aimed at the minimizing negative consequences of the production intensification and optimization of economic indicators in aquaculture becomes urgent. One of the most promising directions in this regard is the use of probiotic additives demonstrating substantial potential for increasing productivity in the farming of aquatic organisms. Purpose. The aim of the present study was to evaluate the fish farming parameters of fingerlings of the F1 hybrid Acipenser gueldenstaedtii Brandt, 1833 x Acipenser baerii Brandt, 1869 with short-term administration of probiotics of enzymatic and antimicrobial spectrum of action into the diet. Materials and methods. The research work was carried out in the conditions of an integrated fish farming enterprise in the Volgograd region. The material was 900 specimen of fingerlings F1 Acipenser gueldenstaedtii Brandt, 1833 x Acipenser baerii Brandt, 1869 (RoLo) at the age of 53 days, which were divided into 3 groups (control, experiment No. 1, experiment No. 2). Fish’ diet consisted of feed with a crude protein content of 56.0±1.5%. The experimental groups of fish additionally received probiotic supplements as part of their diet: experiment No. 1 – a multi-strain probiotic with an antimicrobial spectrum of action (strains Bacillus velezensis MT55, B. velezensis МТ155), experiment No. 2 – a multi-strain probiotic with an enzymatic spectrum of action (strains B. velezensis MT14, B. velezensis MT42). The compound feeds of both experimental groups contained 0.1% probiotic powder. The experiment was carried out for 10 days. To assess the fish farming criteria, morphometric characteristics of fish were measured at the beginning and end of the experiment. The significance of the differences in the obtained values was determined using the ANOVA test. The differences between the groups were considered significant at p <0.…

Substrates for the isolation of bacteriocins: review
type: item
description: Background. Due to the increasing demand for fish products, the stock of wild fish is continuously being depleted. This leads to a high level of aquaculture development in the world. The high content of microorganisms in the water, including pathogenic ones, can negatively affect its quality and safety. Salmonella is a particular danger to aquaculture facilities. Hydrobionts can be carriers of this bacterium, which, when ingested, causes acute intestinal infection. This is especially important when eating raw products such as mussels, mollusks, and fresh fish. Currently, antibiotics are used to combat pathogenic microorganisms, the negative effects of which have been proven all over the world. In this regard, there is an urgent need to find effective solutions aimed at combating the negative impact of pathogenic microorganisms on aquaculture facilities. The use of bacteriocins, which cause the suppression of growth and death of pathogenic microorganisms, is considered promising. The effectiveness of probiotic drugs and bacteriocins can be improved by using beneficial bacterial strains present in the natural habitat of animals. This approach will make it possible to create specialized lines of probiotic drugs of different spectrum of action (antioxidant, antimutagenic, enzymatic, and others) that will promote the development of animal husbandry and minimize the use of antibiotics for the treatment of bacterial diseases. To create an effective feed additive based on bacteriocins in the fight against salmonella, it is necessary to select optimal conditions for the cultivation of new producing strains for maximum bacteriocin yield. Purpose. Review and identification of potential culture media for growing bacterial strains present in the natural habitat of animals producing targeted bacteriocins. Materials and methods. In the course of the study, a comparative analytical method was applied. The information base is based on the analysis of data presented in open scientifi…
