Abstract

Live weight components, dressing percentage, proportion of carcass cuts (hindside, foreside and ribs) and constituents (muscle, fat and bones) were evaluated in 32 Saanen kids slaughtered on different live-weights (8,4 - 28,0 kg) and age from 60 to 130 days. As slaughter-weight increased, hot and cold dressing percentage had a linear increase; head, legs, visceras, kidneys, liver and heart percentage had a linear decrease and skin, blood, kidney fat and fuil and empty gastro-intestinal system percentage did not change. The proportion of ribs increased, hindside decreased, and foreside proportion did not change. The increase in slaughter-weight led to an increase in the percentage of muscle and fat, and a decrease in bones. It was also observed an increase in loin eye area, as well, in carcass measures (internal and external length, thorax depth and leg length). Dairy kids must be reared to produce heavier carcass.
