Values of pH1 and pH24 in the longissimus dorsi muscle, the content of intramuscular fat (IF) and the percentage of lean meat (by a two point method) were measured. Genotypes of RYR 1 were determined by a DNA test and frequencies were as follows: Large White (LW) 26 NN and 8 Nn, Landrace (L) 20 NN and 8 Nn, Czech Meat Pig (CM) 13 NN, 21 Nn and 9 nn. The differences in LW pigs between NN and Nn genotypes were not significant. PSE meat was found in the Nn genotype only (5.88%).
