AbstractGilts of Polish Landrace, Polish Large White, Pulawska (Polish native breed), Duroc and Pietrain breed were slaughtered at 60, 90, 120, 150, 180 and 210 days of age (six animals in each age group). The content of total and soluble collagen of gilts was measured in m. longissimus dorsi (LD) and m. semimembranosus (SM). Breed had no effect on collagen content but age of gilts had a significant impact on collagen content m. longissimus dorsi (LD) had higher content of collagen than m. semimembranosus (SM). In high carcass leanness’ breed (Pietrain) soluble collagen content increased with age while in low carcass leanness’ breed (Pulawska breed) soluble collagen content decreased with age. It was also stated that the roasted meat had higher collagen content then the raw meat. Favourable characteristic of tenderness (more tender) between analysed breed of pigs was found in Duroc breed.
