The article describes the results of studying crossbred cattle. Under equal keeping conditions and moderate feeding the sons of the Red Steppe mothers and the Red Danish and Holstein fathers (groups I and III) used 7-19% less feed units and 6-15% less protein per 1 kg of weight gain than crossbred bull calves of the Red Steppe and Angler, Black-motley and Holstein breeds (groups II and IV). No regularity was found in the consumption of feed per 1 kg of weight gain between the sons of breed improvers of different categories and interbreed hybrids.
