Summary. One of the most powerful factors shaping resistance of the newborn is colostrum. Its qualitative characteristic is reflected in the formation of immunity, protecting organizm from environmental factors. Study of the dynamics of changes in the level of amino acids in the colostrum of infected and healthy animals allows an assessment of the resistance of the newborn calves and forming his immunity. Purpose of the study was to investigate the qualitative characteristics of colostrum from healthy and sick with leucose number of cows on the dynamics of the level of the amino acid composition. Two groups of cows were selected: first – positive and diseased, and second – cows free of infection. The colostrum from these cows was investigated on the 1st and 5th day on a liquid chromatograph SHIMADZU (Japan) to determine the dynamics of quantitative characteristics of amino acid content. Dynamics of sharp reduction of amino acids was installed in colostrum of diseased cows in the first 5 days. Dynamics of the same qualitative characteristics of colostrum from healthy animals on the level of amino acids shows that their number within the first 5 days after calving increases, which makes this product more qualitative, capable of forming a protective forces of the organism.

Keywords: leukemia virus, Elisa, immune diffusion reaction, anti-leukemic activities, colostrum, amino acid, immunological parameters, cattle, newborn calves, infected animals, biochemical studies.
