The effect of feed addition and injection of taurine on intestinal absorption of immunoglobulines in newborn calves and formation of native resistance during rearing was study. In the 1 experiment 5 newborn calves were given three times by 0.3 g of taurine in water during first days of life and 5 control calves were watered by 50 ml of saline. Then in the course of 6 days the dose of taurine was elevated in 3 times; the blood samples were obtained at 24 hours after the birth and then on the 10, 20 and 30 days of life. The 2 experiment was performed on 20 calves using the same scheme in farm conditions. In the 3 experoment 10 calves of 10 to 20-day age were subcutaneously introducted every day by 40 mg of taurine. The next day after the first watering of taurine the level of immunoglobulins in blood was increased by 22% in compare with the control. After days of taurine watering the indices of non specific activity (bactericide, lysocymic and phagocytic activity) and number of T-lymphocytes were increased, that was accomplished by the decrease in disease cases and the increase in average daily live weight gain (by 23%). The similar shifts were observed in the 3 experiment after subcutaneous introduction of taurine at a dose of 1 mg/kg of live weight, indicating the possibility of immune system stimulation through its peripheral structures using micro doses of taurine
