Celem pracy była ocena cech rzeźnych i parametrów jakości mięsa wieprzowego o zróżnicowanej kruchości. Mięso do badań pozyskano od 60 tuczników mieszańców F1 (wbp x pbz), z czego 50% stanowiły loszki i 50% – wieprzki. Masa ciała ubijanych tuczników wynosiła ok. 106–112 kg. 24 h po uboju określano stopień otłuszczenia i umięśnienia tuszy. Ocenę jakości mięsa wykonano na próbach mięśnia longissimus...
Celem pracy było określenie wpływu klas uformowania i otłuszczenia tusz wołowych ocenianych systemem EUROP na jakość mięsa. Badano populację 216 tusz krów rasy nizinnej czarno-białej, reprezentującą trzy klasy uformowania i cztery klasy otłuszczenia w celu określenia zależności pomiędzy jakością mięśnia longissimus thoracis a klasami EUROP. Ocena jakościowa mięśnia obejmowała pomiar pH₂₄, parametry...
