Research was executed on three weeks old calves, witch were transported for 45 minutes at the distance of 10 km. The calves’ blood was collected in 6 series: just before and immediately after the transport and then in 24^th and 72^nd hour and later: 7^th, 14^th, 21^st day after the animals ware located in calf shed. The number of leucocytes was determined in whole blood, the smear was done, and lymphocytes were differentiated on: T, B, CD4 and CD8 cells with the immunofluorescence method including monoclonal antibodies. The concentration of cortisol was determined with RIA methods, while the concentration of glucose was detected with oxidate method. The significant increase of cortisol and glucose concentration was noticed and marked decrease in the amount of lymphocytes T and B in peripheral blood was detected directly after the transport. The increase of T lymphocytes concentration was observed 72^nd hours, and B cells 14 days after the transport. In the 24^th hours after of transportation the higher concentration of lymphocytes CD4 and lower concentration of CD8 cells was noticed.
