The article studied the meat productivity of Caucasian rams born singles and twins, as well as the influence of the introductory crossing of Caucasian breed queens with Dzhalginsky merinos rams of the 2Md-2S line on the meat productivity of the resulting crossbred offspring. The control slaughter at 6 months of age showed that the carcass weight advantage was 20.6% in single rams over twins, crossbreeds Dzhalginsky Merino x Caucasian over purebred peers 8.2%. The advantage of singles and crossbred rams was also observed over twins and purebreds in the yield of cuts of the first grade, meat-and-bone ratio and slaughter yield.
