Abstract :

In fatteners of six genetic groups the slaughter traits were studied based on carcass weight standardized to 85 kg hot weight. The highest mean lean meat content of carcass was found in fatteners from Line 890 – 59.18%, followed by [(L×Y)×D] – 57.08, [(L×Y)×(D×P)] – 56.73, L×Y - 56.57%, L – 56.18 and L×D – 56.00%. The effect was confirmed of genetic group and sex on lean meat content of carcass and related traits. Significant effects of interaction between genetic group and sex were noted for: weight of loin, weight of belly and weight of ham without external fat and skin, backfat thickness over shoulder and over back, and on sacrum point I. No CC genotype at the RYR1 locus was noted among fatteners with highest lean meat content (Line 890).
