TRANSAMINASE (GOT AND GPT) ACTIVITY IN SKELETAL MUSCLES OF CATTLE, PIGS AND POULTRY

Transaminase (GOT and GPT) activity was measured in fattening pigs and young bulls muscles obtained 24 and 48 h after slaughter, respectively; in broiler chicken pectoral and thigh muscles obtained 24 h after slaughter; and in m. longissimus dorsi muscle of pigs of diverse quality. Variation of tramsaminases (GOT and GPT) activity is higher among pigs muscles than among bull muscles. Activity of both enzymes depends slightly on their intra vitam physiological activity. The GPT activity in chicken pectoral muscles is considerably lower than that in thigh and skeletal muscles of pigs and bulls. Pigs PSE muscles exhibit lower GOT and GPT activity than muscles of standard quality and DFD meat. Cold storage of muscles has no significant effect on the activity of either transaminase.
