Abstract :

Investigation was carried out on 96 [(Polish Large White × Polish Landrace) × (Duroc × Pietrain)]
fatteners. The results concerning the influence CAST × RYR1 genes interaction on some meat quality parametres suggest that incidence of faulty, exudative meat appearing in some stress-resistant fatteners (CC genotype in relation to RYR1 locus) and also normal meat in some stress-sensitive fatteners (TT genotype in relation to RYR1 locus) may be due to simultaneous modifying effect of genotype in relation to CAST gene on post mortem changes in muscle tissue.
