Resumo

This study was conducted to evaluate the in vivo and carcass characteristics of goats and sheep sold for slaughter, which originated from different regions of Ceará State, Brazil. Thirty-six (36) mixed-breed, uncastrated male animals (18 goats and 18 sheep), acquired from street markets, which were raised in an extensive production system from the regions of Quixadá, Sobral, and Tauá, were used in this experiment. Before slaughter, the animals were weighed, and body measurements were taken and the body condition score was assessed. Post-slaughter, the carcasses were weighed, morphometric measurements were obtained, and the commercial cuts were weighed and their yields were calculated. The mean in vivo body weight was 23.83 ± 3.76 kg for the goats and 25.22 ± 5.25 kg for the sheep; the body condition score was close to 2, and the mean age was 12 months, with no differences between the species. No differences were found between species and origin for the weights and yields of carcass or for chilling loss. The carcass conformation values were considered poor, and the fat cover was classified as too lean, with the goat carcasses considered superior to the sheep carcasses in these respects. The sheep had higher values for loin-eye area, subcutaneous fat thickness, and weight and proportion of leg than the goats. Mixed-breed goats and sheep reared in extensive systems in Ceará State and sold in street markets in the capital, irrespective of their origin, reach their slaughter weight at an advanced age and with a lean body condition, resulting in carcasses of a low quality, with a low muscle content and poor fat cover. In the extensive conditions of the state of Ceará, animals of the ovine species have a greater ability for meat production than caprine species.
