The dissertation is focused on assessing the influence of yeast culture and selenium addition on yeast culture in feed diet, on colostrum quality and blood serum parameters. The content of immunoglobulins G and the density of colostrum, as the main parameters of the quality of the colostrum, were evaluated in the first born cows and other cows on the second and higher lactation and compared with each other. At the same time, blood serum parameters were also monitored as supplementary indications of feeding intervention in the feed diet of breeds. The main aim of the work was to evaluate the influence of additions of feed additives on the quality and composition of colostrum. Immunoglobulins G were analyzed in all colostrum and blood serum samples. IgG were determined by the ELISA method. The results obtained indicate that the addition of yeast culture and selenium to yeast culture did not have the expected positive effect on improving the quality and composition of cows' colostrum or on blood serum indicators.
