The immune status of fur animals and its correction

Abstract

Despite the unfavorable economic situation, the fur farming industry continues to develop. In order to improve the profitability of fur production in modern conditions, it is necessary to introduce biologically active additives into the diet of fur-bearing animals. Biologically active additives are the catalyst of many processes: activates metabolic processes, tissues respiration processes, participates in the regulation of lipid peroxidation. Experimental work was carried out to study the effect of biologically active drugs on the course of Aleutian disease in mink. The results of the studies confirmed the expediency of their application. The paper presents material on the results of biochemical and immunological studies of the blood of mink, spontaneously infected with the ABN virus and experimentally infected with the culture isolate of the virus "Sapphire" ABN. Biologically active preparations of subalin and Reaferon -EU-lipint were introduced into the ration of animals of experimental groups. When analyzing the results of biochemical and hematological blood tests for 45 days, the animals of the experimental group experienced a significant decrease in the level of total serum protein by 14%, decrease in the content of y-globulin by 92% compared with those of the control group. At the mink of the experimental groups, RIEEF showed a positive result on day 14, a dubious result on day 21 and 30, and a negative result on the 45th day of the experiment. The use of biologically active drugs in the complex of symptomatic treatment of patients with Aleutian mink disease has a positive immunomodelling effect on the metabolic processes in the Nork organism and helps increase body resistance of animals to adverse conditions until maturity of fur.
