RELATIONSHIP BETWEEN MEAT QUALITY TRAITS AND POLYMORPHISM OF  MYF -3 AND  MYF -4 GENES IN CROSSBRED PIGS.

The aim of the research was to identify the relationship between meat quality traits in pigs differing in Myf-3 and Myf-4 gene polymorphism. Such traits as pH₁, electric conductivity, water holding capacity, drip loss and meat colour lightness, as well as the chemical composition of the longissimus lumborum muscle were determined. The study was carried out on 93 (47 barrows and 46 gilts) crossbred pigs (Polish Landrace x Polish Large White sows mated to Pietrain sires). All pigs were certified as NN and Nn genotypes in respect to RYR1 gene locus. No distinct differences in meat quality traits with respect to Myf-3 or Myf-4 pig genotype influences were found. On average, the meat quality traits were in the range ascribed to normal meat quality classes. Nevertheless, the mean values of pH₁ in pigs of the Myf-4 BB genotype were significantly higher (P

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.
