Abstract :

The effect was analysed of CAST and RYR1 genotypes and their interactions on selected LL muscle quality traits in 201 fatteners of three four-breed crossbred groups. CAST/RsaI genotype affected WHC, drip loss at 96 h post mortem and protein and water content of muscle. Among analysed meat quality traits affected by CAST/RsaI genotype, animals of AA genotype were characterized by most desirable values. Significant interactions between CAST/RsaI and RYR1 genotype indicate that quality of meat should be considered not only as a result of genotype effect at each locus, but also as their combined effect.
