“…In view of the advantages of feedlotting lambs for slaughter and the increase in production costs that this system entails, means to minimize feeding costs in feedlots have become the object of studies, considering that this is one of the main factors responsible for that increase (6) . The adoption of diets with a large amount of concentrate ingredients in sheep farming has gained prominence in research developed in this area.…”

In animal production, a large part of financial resources is destined to animal feed, so the use of low-cost diets with maximum production efficiency is crucial. The present study evaluated the effects of a high-grain diet and the use of residual frying oil on the productive performance and carcass characteristics of lambs. Fifteen lambs were distributed into three groups in a completely randomized design in which they were fed a control diet, a high-grain diet, or a diet with the inclusion of residual frying oil, for 40 days. There was no difference (P > 0.05) between the control and frying-oil diets regarding the daily intakes of dry matter, crude protein, mineral matter, neutral detergent fiber, or total carbohydrates. The high-grain diet reduced the intake of dry matter and nutrients, negatively affecting weight gain. The highest means for final weight, total weight, and daily weight gain were obtained with the control diet and the diet containing residual oil, which did not differ from each other (P> 0.05). Slaughter weight and hot and cold carcass weights decreased with the high-grain diet. There was an effect (P < 0.05) of frying oil inclusion on the carcass characteristics of the lambs. The diets did not affect (P > 0.05) carcass yields. The animals on the high-grain diet showed unsatisfactory production performance, with impaired carcass characteristics. The inclusion of frying oil led to greater weight gain as well as more attractive carcass characteristics, making it the most viable alternative in this research.

“…A eficiência produtiva de um sistema pecuário com o objetivo de terminação é relevante para a lucratividade. Isto ocorre devido aos custos com alimentação representar um dos maiores gastos em sistemas pecuários de terminação, sendo que para sistemas de terminação em confinamento, esses custos são ainda maiores, resultando em menor rentabilidade do sistema (Peripolli et al, 2016;Romão et al, 2017;Simões et al, 2019). Em concordância com nosso estudo, que apesar da maior receita/animal, o SI também resultou no menor lucro/animal, devido ao custo com alimentação ser mais alto.…”

“…. Para a compreensão do total dos custos operacionais, considerou o custo com a alimentação representando 76% do total operacional, conforme reportado porRomão et al (2017) em uma análise econômica para terminação de ovinos. Dessa forma, são incluídos nos 24% restantes dos custos operacionais, medicamentos, manutenção e a água fornecida aos animais.…”
