Effects of the rearing system on meat quality in young kids
Thirty twin male kids were allotted to two rearing systems based on feeding regimes: 15 kids nursed by their dams (ND), or 15 kids fed a commercial milk replacer and controlled intake (CR). They were slaughtered at a 10 kg live weight. After slaughter, pH was measured on the Longissimus dorsii (LD), Semimembranosus (SM) and Triceps brachii (TB). Carcasses were chilled for 24 h, and pH, Warner-Brazler shear force (WBSF), colour and water holding capacity (WHC) were determined in the LD, SM and TB muscles. Compared with the ND-raised kids, the TB muscle from CR-raised kids had higher L and lower WHC and pH 24-h postmortem. TB muscle had a higher final pH, greater firmness, and a lower WHC than the LD and SM muscles. In this experiment, raising goat kids on a commercial milk replacer, rather than suckling from their dams, had minimal effects on their meat quality.
