Performance and carcass, loin and ham quality in crossbreds from three terminal sire lines

Journal Contribution - Journal Article

This study was designed to compare performance, carcass and meat quality of crossbred of a hybrid sow x three sire lines, i.e. stress positive Belgian Piétrain (BP), stress negative French Piétrain (FP) and Canadian Duroc (CD). BP offspring had a significantly higher carcass yield (p <.001) and lean meat content (p <.001) in comparison with FP, which was higher than CD. BP offspring had significantly lower pH (p <.05), water-holding capacity (WHC) (p <.001) and intramuscular fat (IMF) (p <.001) content in the loin compared to FP and CD, but these meat quality parameters, with the exception of pH, were superior for CD as compared to FP. In accordance with loin quality, pHi, pHu, WHC and IMF of BP were significantly lower (p <.05) compared to CD in the fresh and cooked ham. Most often, FP offspring could not be differentiated from the other offspring, with the exception of cooking loss of the cooked ham. Trained and consumer taste panels resulted in no significant differences (p > .1) in sensory attributes, however, consumers preffered CD based on ranking.
