A program was carried out at the University of Chihuahua, to investigate the carcass characteristics of Criollo goats in Northern Mexico. Male castrated goats were reared on natural rangeland and also given some concentrate supplementation. They were slaughtered in groups of 10 at 8, 12, 16, 20 and 24 kg live weights. At slaughter the weights of all body components were recorded. Carcass measurements and joint weights were recorded on the chilled left half of each carcass which was then completely dissected into lean, fat and bone tissues. These were then weighed. With increasing slaughter weight the proportion of internal body components (viscera, blood, etc.) minus gut contents, increased relative to the external components (head, feet and skin). In some of the goats from the higher slaughter weight groups the gut contents formed up to 29 percent of the total live weight. The dressing percentage based on empty body weight did not show an appreciable increase with increasing slaughter weight. The lean to bone proportion in the carcass rose markedly with the lean forming 56 percent of the carcass weight in the 8 kg group and about 66 percent in the 24 kg group. The proportion of fat in the carcass remained fairly steady at around 5 percent throughout the slaughterweight range, showing a slight increase in the heavier groups. The proportion of the weight of the total lean formed by the Longissimus dorsi muscle fell slightly with increasing liveweight. The results indicate that in terms of yield of lean meat and also edible offal it is better not to slaughter castrated male Criollo goats before 24 kg liveweight MenosA program was carried out at the University of Chihuahua, to investigate the carcass characteristics of Criollo goats in Northern Mexico.
