Evaluation of the effectiveness of a general tonic feed additive for minks under industrial production conditions
type: item
description: Feeding balanced in amino acids, micro and macro elements, vitamins and other biologically active substances is a necessary condition for the productivity and development of fur animals, as well as for obtaining high-quality fur raw materials. Analysis of the amino acid profile of the main productive diet of the mink at JSC Fur Farm “Saltykovsky” revealed a deficiency of the essential amino acids: histidine, tryptophan and threonine, when maintaining a total protein within the normal range. To correct protein metabolism, a hydrolysate from sable and mink carcasses after technological euthanasia and skinning was included in the diet of minks. The hydrolysate is sterile, does not have pyrogenicity, acute and chronic toxicity, does not cause allergic reactions, contains 18 amino acids, including 10 essential, 6 macronutrients (Ca, Na, S, Mg, K, P) and 18 trace elements. A scientific and economic experiment was carried out by a commission on the basis of JSC Fur Farm “Saltykovsky” on standard wild mink 3 months of age, of which 1 control and 2 experimental groups of 120 animals each (60 males and 60 females) were formed. The results of the experiment showed that the feed additive in doses of 2 and 4 ml of a 15% solution per capita mixed with feed of the productive diet once a day for 4 months has a tonic effect on the mink organism.

Market analysis of veterinary medicines for dogs
type: item
description: Medicinal products intended for dogs were studied. According to the statistics of the AllRussian Public Opinion Research Center1, every third family in Russia has a dog. In this regard, maintaining the health of dogs is of great importance both from a psychological and social perspective. The current state of the Russian veterinary market is characterized by a reduction in the number of foreign suppliers. For example, in 2017, there were 867 veterinary drugs of foreign origin in Russia, of which approximately 180 items remained in market, but this number tend to decrease. The shares of foreign and Russian drugs presented in the Russian market are approximately equal, which indicates a great dependence on foreign suppliers. At the same time, many veterinarians prefer to use foreign drugs as the most effective and safe. However, Russian drugs recently appear in the Russian market are corresponding in quality to foreign analogues. Nowadays, they should form the basis for import substitution. The priority for import substitution should be drugs for the treatment of the most common and deadly diseases of dogs, the list of which is established by the national standard of the Russian Federation (GOST R 70040-2022) 2. According to the list, 35 of the most common diseases in practice were identifi for 10 organs and systems of dogs. The method of grading the medicinal products quality previously developed by the authors was used to select medicinal products by a treatment way. As a result, 353 drugs were selected, including 178 foreign and 175 Russian products. It was established that the supply of foreign drugs by the origin of medicines comprises 34 foreign countries, including 8 friendly and 26 unfriendly. At the same time, 148 drugs are supplied from unfriendly countries, and only 30 from friendly ones. The current trend of reducing supplies from unfriendly countries poses a threat of a shortage of medicines to Russia. 1 Russian Public Opinion Research Center (VCIOM). URL…

Prooxidant-antioxidant control of the effectiveness of aerosol therapy for acute catarrhal bronchopneumonia in calves
type: item
description: The results of prooxidant-antioxidant control of the efficiency of various schemes of aerosol complex therapy for acute catarrhal bronchopneumonia in calves using the generally accepted scheme (aerosol treatment indoors with iodotriethyleneglycol solution with intramuscular administration of the drug ”Penstrep‑400“), as well as schemes proposed by us, based on previously conducted studies to determine the sensitivity of isolated microflora to antibacterial drugs (aerosol treatment indoors with iodotriethyleneglycol solution with intramuscular administration of the drug ”Marfloxacin“) and phytobiotics (aerosol treatment indoors with Hypericum perforatum wort extract with intramuscular administration of the drug ”Marfloxacin“) were presented. Black-and-white calves, aged 1–3 months, mixed sex, with clinical signs of acute catarrhal bronchopneumonia were studied. The sick animals were divided into three experimental groups using the envelope method: 1O — experimental 1, n = 20; 2O — experimental group 2, n = 20 and 3O — experimental group 3, n = 20 and placed in separate isolators. During the treatment of animals in group 1O, the general clinical improvement occurred only on the 9.25 ± 0.91 day, while six cases of complications occurred, and two animals died. The treatment of calves in group 2O was accompanied by the general clinical improvement 2.05 days earlier, compared with group 1O, and all animals recovered. Therapy in group 3O contributed to the general clinical improvement already on the 4.90 ± 0.64 day, which is 47.0% earlier compared with the indicators of group 1O, and all 20 calves also recovered. The study of the processes of lipid peroxidation and antioxidant protection in blood plasma of experimental calves in the dynamics of treatment confirmed the best result in 3O group, which was accompanied by a significant decrease in LPO products and an increase in AOS indicators, which already on the 7th day of observation approached the physiological norm.

Influence of complex therapy on amino acid composition of blood in calves with gastrointestinal tract diseases
type: item
description: Significant changes in the amino acid composition of the blood were found in calves with dyspepsia. Amino acid analysis showed a heavy decrease in the levels of specific non-essential and essential amino acids in calves with dyspepsia. The aim of the study was to evaluate the effect of fermented colostrum on the amino acid composition of blood during the treatment of calves with dyspepsia. Three groups of 10 day-old calves were formed for the study. The first group of animals (the control group) was fed regular colostrum without fermentation for 7 days. The second and third groups (experimental) were calves with diarrhea syndrome. The second group of calves was administered 2 ml of Flunex intramuscularly, Roncoleukin 1500 IU/kg intravenously, and Thymogen was administered to calves intramuscularly at a dose of 100 mcg per animal on the 1st and 20th days of life. A full dose of milk was given in the evening milk feeding. The third group of calves underwent the same drug therapy. But in the morning and evening milk feedings they were given a full dose of colostrum fermented by Productiv Acid SE. The use of Flunex, Roncoleukin, Thymogen for the treatment of the disease does not contribute to the full restoration of the amino acid composition of the blood. After treatment, the content of specific essential amino acids did not reach the levels of healthy animals. The total amount of amino acids was also below the control values. Adding fermented colostrum to the diet of calves that were undergoing treatment contributes to the restoration of the amino acid composition of the blood. The content of specific essential amino acids slightly differed from the control values in this group animals. The amount of non-essential amino acids increased significantly and almost reached the control values.

The influence of climatic factors on sunflower ontogenesis in conditions of the Orenburg region
type: item
description: The effect of the variability of certain climatic parameters during the growing season on the cultivation of sunflower (Helianthus annuus L.) in the Orenburg region was studied. It was shown that the growth and development of Helianthus annuus L. are significantly influenced by both humidity and temperature, but the amount of these parameters changes over time due to the ongoing climate change. In this regard, one of the principles of agronomy is to identify relationships between the phases of phenological development in the context of changing weather conditions. It allows to assess the measures aimed at adapting sunflower to a specific cultivation zone. Timely implementation of these measures will enable us to manage the susceptibility of the agricultural sector and predict crop yields. The present study is based on registration of eight phenological phases from sowing to harvesting for three years and assessment of the influence of weather factors of a particular season on both ontogenesis of the crop in general and duration of each phenological phase in particular. According to the results of observations, it was found that the duration of Helianthus annuus L. cv. ‘Poseidon 625’ vegetation in climatic conditions of Orenburg region was on average 99 days and is determined by the timing from the formation of the first and second pairs of true leaves to seed formation. The phenological periods requiring maximum moisture were determined — from sowing to germination and from flowering to seed filling (r = 0.9, the significance level is 90%). The data obtained during the study can be used by farmers and agronomists to determine the optimal timing of sowing oilseeds not only in Orenburg region, but also in each specific region engaged in their production.

Prospects of Serratia plymuthica strain 23B78/1 as a biocontrol agent for tomato protection
type: item
description: Tomato protection from diseases is necessary to obtain high yields of quality fruits. In protected soil conditions, tomatoes bear fruit for up to 265 days, while the fruits are harvested 1 or 2 times a week starting from 60 days after seed germination for early varieties and 100 days for late varieties. When growing tomatoes, especially during the fruiting period, it is optimal to use biological pest control agents, which, unlike chemical ones, are harmless to humans and do not accumulate in the fruits. Existing biological products are not effective enough against the entire range of tomato diseases. It is necessary to look for new strains of microorganisms. This paper presents the results of the study of strain 23B78/1 Serratia plymuthica with the aim of exploring the prospects for its use as a biocontrol agent. Pesticides based on this species are not registered in the Russian Federation. Species identification was determined by 16S gene sequence analysis and biochemical profiling. Antagonistic activity against phytopathogenic fungi was assessed in vitro using double culture method. Phytotoxicity testing was carried out on germinating seeds of tomato. Evaluation of antagonistic effect revealed effectiveness against the following phytopathogenic fungi: Alternaria solani, Botrytis cinerea, Colletotrichum truncatum, Fusarium citri, F. incarnatum, F. duofalcatisporum, F. incarnatum, F. oxysporum, Globisporangium ultimum, Sclerotinia sclerotiorum. The maximum antagonistic effect was observed during paired fusion with fungus B. cinerea, mycelium of which grew strictly in the opposite direction from the bacterium. Germination of tomato seeds in presence of strain 23B78/1 did not reveal any inhibitory effect on seed germination and development of young tomato plants. The conducted research shows that the strain Serratia plymuthica 23B78/1 is promising for creation of biofungicide for protecting tomato plants.

The use of microbiological agents in potato growing in the zone affected by metallurgical production
type: item
description: The efficiency of using microbial agents for growing potatoes in the zone of influence of metallurgical production in the conditions of the Southern Baikal region was assessed. The studies were carried out at three sites near a large industrial aluminum enterprise in the city of Shelekhov in 2015-2016. Microbial agents of Japanese (EM series) and Russian production (Baikal EM1, Fitosporin) were used in the study. It was revealed that the effectiveness of Fitosporin and EM preparations depended to a greater extent on soil’s pH and weather conditions. Thus, growing potatoes on slightly acidic soils using EM agents caused a stable increase in yield by 14-22%, and on alkaline soils, increasing yields were recorded in less than 50% of cases. At the same time, using Fitosporin-M bioagent on alkaline soils resulted in increasing potato yield by 13…22%. Using this bioagent on slightly acidic soils increased yield (by 26%) only in 2016. The results obtained indicate the prospects of further research on the use of biological products in the cultivation of agricultural crops in contaminated areas.

Monitoring of the erythrocyte antigen structure in the gene pool herd of Red Gorbatov cattle
type: item
description: Immunogenetic analysis is of practical interest, allowing us to establish not only the relationship between animals, but also the degree of genetic influence of individual stud bulls on the entire gene pool of the population. While preserving the gene pool, the study of the frequency distribution of blood groups, as well as their changes over time, allow us to judge the processes occurring in closed populations. The research was carried out in the gene pool farm of the Red Gorbatov breed. The brood stock has 8 systems of blood groups. In 2007, 45 antigens were detected in the herd, in 2009 there was a decline in diversity to 38 antigens, but in 2010 their number was restored to 46, by 2017 the total number of antigens had not changed significantly — 47, and in 2022 again 46. The most numerous is EAB system, from 21 to 28 antigens were established in this system in different years. The structure of antigens is unstable, some antigens that were widespread in 2007 (Y2 and C2) decreased to 14…32 % in 2017. New antigens were established — O3, O4, Ox, and A’1. The loss of individual antigens may indirectly indicate the loss of other alleles that have economic importance; therefore, animals with rare antigens should be used in reproduction to a greater extent. The stud bulls whose seed stock is available at that moment have different antigenic composition: from 3 to 17 antigens in different systems. The use of a limited number of bulls can lead to the drift of individual genes.

Modern approaches to the prevention of actinobacillus pleuropneumonia in pigs
type: item
description: Information about the current situation with actinobacillus pleuropneumonia (APP) in the Russian Federation is quite limited, which makes it difficult to assess the effectiveness of current preventive measures and develop new strategies. The diversity and effectiveness of vaccines play an important role. The main aim of the study is a scientific review of modern approaches to the APP prevention in pigs and prospects for the development of a vaccine that provides comprehensive protection against all known serotypes of this pathogen. The methods of systematization, critical analysis, and problem review are used. Over the years, various vaccines have been developed to combat this disease. Inactivated bacterial vaccines provide a strong immune response, but their effectiveness may vary. Based on the outer membrane proteins and three Apx toxoids, subunit vaccines are able to provide protection regardless of the APP serotype. DNA vaccines show promising results but require further research. Live attenuated vaccines contain weakened microorganisms and stimulate strong immunity, but their use also has its own difficulties. Despite all the successes achieved, at the moment there is no reliable and commercially profitable vaccine that would protect against all known serotypes of A . pleuropneumoniae and prevent the carriage and transmission of the disease. The problem of specific prevention of APP requires an integrated approach, including further scientific research, the development of new technologies and innovative methods of vaccination. Scientists increasingly focus on research in the field of oral and nasal vaccines. One of the important advantages is cost-effectiveness and safety during production, as well as convenience and safety of vaccine application. Oral and nasal vaccines can significantly simplify the immunization process, especially in the context of mass vaccination. Studies of vaccines based on external membrane vesicles and transgenic plants show promising …

Epidemiological characteristics of dogs with dental calculus: 392 cases (2012-2020)
type: item
description: Dental calculus is a local irritant to adjacent soft tissues, causing an inflammatory response that contributes to the development of periodontal diseases. Mineralized plaque contains bacterial toxins, which can lead to systemic infections. A retrospective analysis of the oral cavity condition of 392 dogs with dental calculus admitted for a comprehensive dental examination and oral sanitation to the Dentalvet veterinary center in 2012-2020 was conducted. An analysis of epidemiological data was performed to determine the risk factors for dental calculus formation. The study showed that small breed dogs aged 1 to 5 years were included in highrisk group for periodontal diseases. Tables with data on dental plaque and calculus indices, age characteristics of dogs, number of dog groups by skull type and breed, photographs and intraoral X-rays were provided.

Immunological parameters in serous catarrhal inflammation of the udder in lactating cows
type: item
description: The aim of this study is to investigate the immunological parameters of blood in lactating cows with serous-catarrhal mastitis to identify the pathogenetic mechanisms of the disease. The research was carried out in autumn in one of the livestock farms of the Amur region. The object of the study was lactating cows of Holstein breed at 2-4 months of lactation. Groups of cows were formed by 10 animals in each: control (healthy) and experimental (sick with serous catarrhal mastitis). The inflammatory process in the mammary gland of lactating cows was caused by tissue damage and complicated by opportunistic microflora. Protein metabolism disorders (hypoalbuminemia, dysproteinemia) and signs of haemoconcentration (increased haematocrit and haemoglobin, erythrocytosis) were observed in sick animals. Conditionally pathogenic microflora and products of inflammation in the mammary gland stimulated cellular and humoral immunity.
