Abstract
The results of the study of the meat productivity of crossbred young animals obtained from the crossing of ewes of the Aginsk breed with the producers of the Kazakh breed of the Bayys type in a comparative aspect with purebred analogs of the original breed at the age of 6 and 18 months are presented. It has been established that crossbred individuals have a significant advantage in terms of slaughter qualities in the analyzed age periods. So, for the pre-slaughter live weight at the age of 6 months. the superiority was 3.0 %, at the age of 18 months. – 6.2 %, for slaughter weight and slaughter yield – 3.4 and 0.2 %; 7.8 and 0.8 % respectively. Lamb obtained from the slaughter of young sheep of the control and experimental groups at the age of 6 months, depending on the weight of carcasses, corresponded to the first class. The chemical composition of the meat indicates the higher calorie content of meat obtained from crossbred young animals. At the same time, the ratio of protein and fat was optimal when slaughtering experimental young animals at the age of 6 months. Tasting evaluation of broth and boiled meat did not reveal significant differences in organoleptic indicators of control and experimental samples.
