The article discusses the growth rate of lambs of the Zhaidar, Karakul breed and their crossbreeds in different age periods. The relationship between the live weight of newborn lambs and their precocity was revealed. Based on the foregoing, we set a goal, based on the study of lambs of different origin and having different live weight at birth, to establish the possibility of using the size of lambs at birth as a marker for early prediction of their feeding and fattening abilities, meat and sebaceous productivity. Common to lambs of the Zhaidar, Karakul breed and their crosses was that during all studied growth periods there was a direct positive correlative relationship between the size of the lambs at birth and the growth rate, that is, small-sized lambs grew and walked somewhat more slowly than their peers who had at birth, medium and large.
