| Sumario: | The study evaluated the live weight components, objective and subjective carcass characteristics and physical-chemical characteristics of the Longissimus lumborum muscle and the proportion of tissues that constitute the loin of twenty-four intact males lambs, Hampshire Down crossbreed, fattened in a drylot system. The lambs were fed with different diets based on corn grain silage with the addition of sunflower seeds or urea. The treatments did not affect live weight and hot carcass weight at slaughter, carcass yield, blood, skin, reproductive system with bladder, respiratory system, spleen, kidneys and perineal fat, liver, heart, empty gastrointestinal tract, head or feet. There was no significant difference in cold carcass weight, body condition, conformation of carcass, fat covering, fat consistency, meat color, thickness, loin area, crude protein, or ratios of muscle, bones, fat and other tissues of the Longissimus lumborum muscle. Cooking losses, myofibril fragmentation index and colors indexes L*, a* and b*, also did not differ by treatment. The lambs can be fattened with any diets, because there is no difference for the analyzed characteristics |
