Biological Evaluation of Protein Hydrolysate’s Influence on the Mink Organism

Resumo

Abstract—The study was conducted at the Saltykovsky Plemzverosovkhoz state-owned farm in 150 minks selected according to the principle of analogs. We estimated the systemic and local effects of protein hydrolysate obtained by the fermentation of mink bodies. During a diet analysis, we detected a deficit of threonine, an essential amino acid. The body weights of animals from experimental groups fed with 2 and 4 mL of 7% hydrolysate solution were higher by 3.6 and 10.1%, respectively, as compared with the control animals. The total protein concentration was higher by 48.6%; the albumin fraction was lower by 27%. The level of alanine transaminase (ALT) and aspartate transaminase (AST) in the control animals was lower by 29% and higher by 35%, respectively, than in the experimental groups. The planimetric parameters of fur raw materials in the experimental groups were higher by 5.5% than in control animals. Based on the estimates of systemic and local effects of the protein hydrolysate, it is considered to be effective for cage housing.
