The article presents the results of studies of the indicators of live weight and the internal organs weight of purebred Khalkha and crossbreed Khalkha-Suffolk rams, depending on the method of their fattening. Experimental studies were conducted in the Selenga aimak of Mongolia and in the laboratories of the Mongolian University of Natural Sciences. According to the results of the research, it was revealed that purebred Khalkha rams were inferior to Khalkha-Suffolk crossbreed rams in terms of live weight at birth and at the age of 8 months. When fed with rapeseed cake, purebred Khalkha rams had an advantage over half-breeds in terms of absolute heart weight by 0.04 kg and digestive system weight by 0.06 kg, and in terms of pre-slaughter weight by 0.22 and 1.29%, respectively. At the same time, Khalkha-Suffolk crossbreed rams outperformed purebred animals in terms of absolute lung weight by 0.19 kg and relative weight by 0.19%.
