FATTENING AND MEAT QUALITIES OF PIGS OF DIFFERENT GENOTYPES

Abstract

The research shows that concerning fattening qualities the best hybrids are those obtained in four three-breed crossing variants: (BLW×BM)×L (den.), (BLW×BM)×L (ger.), (BKBçBM)×Y (den.) and (BLWçBM×Yof German breed heterosis effect of which is: 10.2; 9.15; 5.0 and 3.7 %, 8.1; 5.3; 7.9 and 3.4 %, 6.2; 5.7; 5.5 and 3.8 %. Superiority of the Danish hybrids over the control group is also established concerning carcass length by 2.1; 1.2 and 1.7 cm, backfat thickness by 2.8; 1.4 and 2.1 mm, loin area by 5.4; 3.7 and 4.4 cm2 , weight of third part of half-carcasses by 0.6; 0.5 and 0.7 kg, meat content in carcass 1.6; 0.8 and 1.2 %.
