Carca？as e componentes n？o-carca？a de cordeiros terminados em pasto de azevém recebendo suplementa？？o concentrada

the study was performed to evaluate the subjective and objective measurements of the carcasses and non-carcasses components of weaned lambs grazing on italian ryegrass pasture fed with different levels of concentrate supplementation (without supplementation, 0,9%, 1,8% of body weight and ad libitum). lambs were slaughtered at 32kg of live weight. after slaughtering, hot carcass, digestive content and weight of non-carcass components were recorded. weight of cold carcasses was assessed after the refrigeration for 24h at 5°c. weight, yield and carcasses measurements were taken and then the leg and carcass compactness were calculated. data were subjected to regression and simple correlation analysis. the concentrate supplementation levels had a positive linear effect on the weights and yields of hot and cold carcass and leg and carcasses compactness. supplementation of weaned lambs grazing on annual ryegrass enabled to get carcasses of better conformation and fat covering. these effects may result in better price opportunities and marketing for farmers.
