CHANGES OF IMMUNOLOGICAL REACTIVITY ORGANISM OF COWS DURING THEIR GENDER CYCLE AND UNDER THE INFLUENCE OF SEPARATE VITAMIN DRUGS
The article is devoted to the study of immunobiological reactivity of cows during their sexual cycle and under the influence of vitamin A and trivitison (vitamin A, D<sub>3</sub>, E). The relevance of the study is to study changes in the immunobiological reactivity of the body of cows in certain periods of their reproductive function and under the influence of individual biologically active substances. The purpose of our research is to study the dynamics of protein fractions and antigenic properties of cows serum proteins during their sexual cycle with the use of vitamin preparations. The results obtained in our experiments indicate a higher synthesis of whey protein in cows treated with vitamin A and trivitamin throughout the study period.
