Summary. Influence of germivit on the immune status of bull-calves is studied in the article. Germivit – preparation derived from wheat germ, it includes vitamins, amino acids, macro- and microelements. Germivit is successfully used in various branches of animal husbandry. Increase of bactericidal activity of blood serum was observed under the influence of a germivit in bull-calves of the first test group. Reliable differences on lysozyme activity of blood serum at 15-month age were recorded in representatives of the third test group (3,11% (р<0,01)). Beta- (β-) and lytic activity of blood serum throughout all experience at animals of the control and test groups changed slightly and doubtfully. Under the influence of germivit to 15-month age the substantial increase of number of T-lymphocytes in blood of bull-calves of test groups was observed. Similar consistent pattern is determined and at calculation of quantity of В-lymphocytes. Under the influence of germivit at bull-calves of test groups at 15-month age reliable decrease in number of the CEC in blood in comparison with control contemporaries for 4,06-4,73% was observed (р<0,01-0,001). At 18-month age this difference increased a little and made 6,02-7,18% (р<0,001). The specified circumstance testifies to decrease in antigenic load of an organism of animals. The presented results of researches testify the positive influence of germivit on the immune status of bull-calves.
