In Kazakhstan, special importance is attached to the development of meat and fat sheep breeding, the purpose of which is to increase the production of environmentally friendly lamb and mutton in transhumance. The problem of conservation and rational use of the pedigree gene pool of meat-and-fat sheep breeding is an important part of the program for the restoration and development of this industry in the country. One of the important tasks of meat-and-fat sheep breeding is the development of desert and semi-desert pastures to obtain competitive sheep products. The purpose of our research was to study the inheritance of fat tail parameter in the offspring of rams and ewes with different fat tail sizes. The work was carried out in the “Ortay” peasant farm of the Ordabasy district of the Turkestan region. It has been established that in the case of animals’ selection (♂ small fat tail x ♀ large fat tail), the proportion of ewe hoggs and ram hoggs with a desirable small fat tail amounted to 27.6-29.2%, respectively, and lambs with a medium fat tail size of 24.4-20.1%, and with a large size of 48.0 and 50.7%, respectively. In the second selection option (♂ small fat tail x ♀ medium fat tail), lambs were obtained with a small fat tail by sex, respectively, 43.4-41.8%, with a medium size of 42.8 and 43.8%, with a large size of 13.8 and 14.4%.
