Treść
The aim of this study was to determine the effect of pre-slaughter fasting on the meat quality of both genders of offspring of Duroc boars at approximately the same pre-slaughter lairage time. The carcasses of the pigs subjected to longer pre-slaughter fasting (24 compared to 18 hours) had better technological meat quality with a similar weight and muscle percentage, as evidenced by significantly higher pH, lower electrical conductivity (EC), lower drip loss from fresh and thawed meat, lower lightness (L*) and increased redness (a*). The length of pre-slaughter fasting had no effect on the sensory traits nor the shear force of the meat. Differences between sexes were visible in the higher lightness (L*) and yellowness (b*) of the longissimus lumborum muscle of barrows compared to gilts with similar muscle content and basic chemical composition. The authors observed no interactions between the length of preslaughter fasting of finishers and their sex that had an effect on the quality of the meat.
