Relevance . The article presents the results of using domestic and imported breeding rams on Akzhaik ewes. The productive indicators of offspring obtained from the use on Akzhaik ewes along with Akzhaik rams also rams of North Caucasian and Kuibyshev breeds were studied. The results of growth and development of young animals, control slaughter of rams in 4.5 months, as well as wool qualities of ewes are given. It was established that all the sires of meat-wool breeds with cross-bred wool used in the experiment were characterized by rather high hereditary indicators of meat and wool productivity, with slightly better offspring of rams of imported selection. The resulting young stock has the physique and good precocity inherent in meat-and-wool sheeps. Results . Research has established that all semi-fine-fleeced rams of meat-wool breed with cross-bred wool used in the experiment were characterized by rather high hereditary indicators of meat and wool productivity, with slightly better offspring of rams of imported selection. Rams of both local and imported selection steadfastly pass on their meat and wool qualities to their offspring. The resulting young stock has the physique and good precocity inherent in meat-and-wool sheep. In the farms of the region engaged in the breeding of meat-wool semi-fine-wool sheeps, for the improvement and increase in productivity, it is possible to use breeding material of both domestic and imported selection.
