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...
The experiment was carried out on 95 samples of the longissimus dorsi muscle (LD). They were collected from carcasses classified to meatiness classes E, U and R (24, 52 and 19 samples, respectively) of pure-bred pbz porkers, hybrids of white pigs sows (wbp x pbz) with Pietrain boars and those of Dutch pigs (Landrace x wb) x wb. After slaughter, blood samples were collected in porkers for DNA analysis...
Badanie prowadzono w miesiącach letnich (czerwiec, lipiec, sierpień). Warchlaki (20 wieprzków i 20 loszek) od wieku około 80 dni były utrzymywane w półotwartym kojcu łączącym się z wybiegiem. Na terenie wybiegu usytuowane były karmniki i poidła. Zwierzęta otrzymywały też codziennie świeżo skoszoną zielonkę z lucerny lub koniczyny perskiej. Okres tuczu trwał średnio 90,25 dni (od masy ciała około 24,74...
