| Popis: | Background: Carcass and sheep meat quality are influenced by several factors, such as race, age, slaughter weight, type of diet, and dietary supplementation. Objective: To evaluate the effect of castration and vitamin E supplementation on performance, carcass characteristics and meat of lambs slaughtered at 45 kg. Methods: Thirty-two male lambs (16 castrated and 16 not castrated) were fed diets with or without the inclusion of vitamin E. The animals had an average age of 180 ± 20 days and a mean weight of 25.1 ± 4.6 kg. Performance was evaluated for 56 days, and the animals were slaughtered when reaching a weight of 45 kg. The experimental design was randomized blocks based on initial weights, and variables were assessed by a 2x2 factorial design (castrated and intact, supplemented or not with vitamin E, with a probability of 5%). Results: Higher proportion (p |
