Abstract:
The authors of this study determined some indices of cellular immunity T and B – lymphocytes and the total number of leucocytes under the influence of preparations Timocen and Timalin. It was noticed that the percentage level of lymphocytes T-total, T-active and B-active in the calves from experimental groups 1 and 2 increased. These calves recovered 3-4 days earlier than expected and without relapse.
