MEAT PERFORMANCE OF STEERS OF DIFFERENT GENOTYPES
Abstract
Researches on meat performance of young Limousine and Aberdeen Angus breeds reared in conditions of Pripyat Polesye were conducted. Parameters of pre-slughter live weight, slaughter yield, carcass yield and visceral fat, morphological composition of half-carcasses of steers at the age of 18 months were studied. The obtained results confirm the advantage of young beef breeds over coevals of black-motley breed: in slaughter yield - by 1.3-5.3%, in carcass yield - by 1.0-5.9%, in content of pulp and trimmed meat - by 2.4-3.9 and 0.4-6.0%.
