Productive Traits of Meat Calves of Different Genotype

Abstract

It is determined that cross men-anzhu x limousine calves grown at suckling under cows up to 160-170 kg of live weight surpass coevals of black-motley breed and cross aberdin-anguss x black-motley grown on technology of milk cattle breeding on meat productivity and meat quality. So on slaughter outcome the difference with black-motley breed calves made 20,1 %, with aberdin-anguss x black-motley - 12,3%, on carcass outcome - 19,3 and 11,6 %, on frozen carcass weight - 13,5-8,5 kg, on meat outcome from ½ of carcass - 1,9 and 8,1 kg correspondingly. Differences are correct at Р<0,001. As well the content of flesh meat of ½ carcass of men-anzhu x limousine calves was 11,9 kg or 42% higher (Р<0,001) than that of black-motley and 8,1 kg or 25 % higher (Р<0,05) than that of aberdin-anguss x black-motley. As well the meat of men-anzhu x limousine calves contained 3,29 and 4,29 % (Р<0,001) less water and protein and fat 1,7 % (Р<0,01) and 2,12 % (Р<0,001) and 1,8 and 2,34 % (Р<0,001) higher correspondingly compared to black-motley and aberdin-anguss x black-motley calves.
