Young bulls are finished during 260 days at open feedlot with capacity of 500 feeders and pen size of 40 to 100 head. Rearing program included some measures to prevent the stresses. On average daily DM intake was 7.9 kg/head, ADG - 1250 g, feed conversion 6.32 kg/kg BW gain, hot carcass weight - 349.6 kg, dressing yield - 58.2%. The main advantages of bull carcasses in comparison with steer (accordance with our review of many studies) are the low internal fat content (5.7 vs 14 kg) and fat trim (9.7 vs 50 to 87 kg), high content of edible parts of carcass (82.35 vs 80.0%) and more desirable amino-acid composition and ratio saturated fatty acid/polyunsaturated fatty acid. The best cuts for fast cooking of bull carcasses consisted 18.9% of weight and 44.8% of market value. Fattening of bulls instead of steers is recommended for small feedlots and family farms.
