During the slaughter, after animals’ stunning with CO2
, the blood was withdrawn
for identification of CAST and RYR1 genotypes. Subsequently, carcass meat deposition
rate was measured, as well as the thickness of longissimus dorsi (LD) muscle and
backfat between the 3rd and 4th rib, 6 cm from the line of carcass partition into sides, by
means of optic-needle (CGM apparatus, Sydel, France), as well as hot carcass weight
of pigs established. Mean per cent carcass meat deposition amounted to 55.39±0.40
and hot carcass weight to 87.75±0.55 kg
