In this experiment, the meat productivity (morphological and varietal composition of carcasses, yield of anatomical cuts) of experimental rams of new genotypes was assessed: Texel x Soviet Merino and Texel x Ebilbaevskaya. Purebred animals of the Soviet Merino and Edilbaevskaya breeds were studied as control variants. As a result of the experiment, the pre-slaughter weight of crossbred animals was dominant relative to purebred animals, based on which the weight of the fresh carcass of crossbred animals naturally increased by 2.09 kg (P < 0.01) and 2.87 kg (P < 0.01), and the slaughter yield by 2.30% and 2.77% over purebred original breeds. It was found that the meat coefficient of F1 rams was higher due to the increase in the yield of pulp by 20.63% (P<0.01) and 16.63% (P<0.05) relative to purebreds. A stable change in fatty acids in the composition of lamb and subcutaneous fat towards optimizing the ratio of unsaturated to saturated was revealed. Hybridization, as a method of improving the meat productivity of sheep, using rams of meat breeds, has proven its effectiveness in our studies.
