Effects of the rearing system on meat quality in young kids

Argüello A., Ginés R., López J.L., Capote J.

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.
