During the initial period of life, especially in the first few months, the growth of young animals is strongly influenced by the level of milk feeding, as their entire nutritional requirements are covered by milk. The results showed that the lambs ate an average of 77.89 kg of milk before milking, with the highest amount of milk eaten in the first month of life. In each subsequent month of the experimental period, weight gain increased, while milk consumption per 1 kg of body weight gain decreased. In the first month of life, the average daily weight gain of the young rams was 0.151 kg and the milk consumption per 1 kg gain was 6.09 kg. In the second and third months, these values were 0.163-4.86 and 0.205-4.56 kg respectively. In the first month of life, the young ewes gained an average of 0.138 kg per day and consumed 6.54 kg of milk per 1 kg of body weight gain. In the second month, the average daily gain was 0.158 kg and milk consumption was 4.87 kg; in the third month, the values were 0.199 and 4.48 kg. On average, the lambs consumed 6.31 kg of milk per 1 kg of gain in the first month of life. It was found that growing lambs from three months of age to weaning by the suckling-milking method increased milk yield per sheep by 28.0 kg and did not have a negative effect on body weight and wool productivity of the lambs compared to growing with mothers. Feeding oil cake at the rate of 150 g per day per animal during the period from three to five months with simultaneous milking their mothers increased the body weight of lambs at weaning by 10.7-11.7 % and wooliness - by 26.5-24.1 % compared to other groups.
Keywords: gain, body weight, milk productivity, wool productivity, milk yield.
