Abstract

In conditions of "Batai-Shu" LLP breeding farm in Zhambyl region crossbred lambs were first obtained by crossing cryopreserved semen of the imported sheep breeds of Poll Dorset and ewes of Kazakh meat and wool producing breed. These results indicate that the genetic backgrounds were introduced into Kazakh meat and wool producing sheep; content of visceral and intramuscular fat of crossbred male lambs is low, and the rate of pure meat is improved. Dorset lambs give a good foundation for growing a new type of Kazakh meat and wool producing breed. In the future, the obtained crossbred lambs of different generations will be grown under the supervision and serve as a basis to breed a new type of Kazakh meat and wool producing breed which meat productivity will be significantly higher than the original purebred breeds.
