Resumo: | The aim of this study was to evaluate the effects of four crude glycerin levels in the diet of feedlot lambs on performance, carcass characteristics, and meat quality. Forty three-month-old crossbred Santa Inês x Dorper lambs weighing 18.2 ± 0.169 kg were used in a completely randomized design, with four diets and 10 replicates per diet. The animals were housed in individual pens. The trial period (42 days) was preceded by 14 days of adaptation to handling and diet. Final body weight (FBW), empty body weight (EBW), average daily weight gain, feed conversion, and feed efficiency did not differ with crude glycerin levels in the diet. Nutrient intake (dry matter (DM), ether extract (EE), crude protein (CP), and neutral detergent fiber (NDF)) did not differ depending on crude glycerin levels. In the evaluation of carcass characteristics, there was a quadratic effect due to crude glycerin levels on hot carcass yield (maximum point- maxP = 9.73%), leg perimeter (maxP = 9.45%), fat thickness (maxP = 7.41%), and leg weight (maxP = 8.69%). Loin weight and conformation showed a linear increase as a function of crude glycerin levels. The other studied variables were not affected by crude glycerin levels in the diet. In the non-carcass components, the full gastrointestinal tract, mesenteric fat, omental, and perirenal fat were not influenced by crude glycerin levels. Regarding meat quality, no effects were observed on the parameters evaluated in the longissimus dorsi. The addition of up to 15% crude glycerin in the lamb's diet does not affect its performance, however, the addition of up to 8% improves carcass characteristics and maintains meat quality. |

Foram utilizados 40 cordeiros mestiços Dorper x Santa Inês com três meses de idade e peso corporal médio de 18,2 ± 0,169 kg, distribuídos em delineamento inteiramente casualizado, com quatro dietas e 10 repetições por dieta. Os animais foram alojados em baias individuais. O período experimental (42 dias) foi precedido de 14 dias de adaptação ao manejo e às dietas. O peso corporal final, peso de corpo vazio, ganho de peso médio diário, conversão alimentar e eficiência alimentar não diferiram com os níveis de glicerina bruta na dieta. O consumo de nutrientes (matéria seca, extrato etéreo, proteína bruta e fibra em detergente neutro) não diferiu em função dos teores de glicerina bruta. Na avaliação das características de carcaça, houve efeito quadrático devido aos níveis de glicerina bruta sobre o rendimento de carcaça quente (ponto máximo-maxP = 9,73%), perímetro da perna (maxP = 9,45%), espessura de gordura (maxP = 7,41%) e o peso da perna (maxP = 8,69%). O peso do lombo e a conformação apresentaram aumento linear em função dos teores de glicerina bruta. As demais variáveis estudadas não foram afetadas pelos níveis de glicerina bruta na dieta. Nos componentes não carcaça, verificou-se que o sistema gastrointestinal completo, gordura mesentérica, omental e gordura perirrenal não foram influenciados pelos níveis de glicerina bruta. Na qualidade da carne, não foi observado efeito nos parâmetros avaliados no longissimus dorsi. A inclusão de até 15% de glicerina bruta na dieta do cordeiro não afeta seu desempenho, porém a inclusão de até 8% melhora as características da carcaça e mantém a qualidade da carne.UEL2024-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4795810.5433/1679-0359.2024v44n2p345Semina: Ciências Agrárias; Vol. 44 No. 2 (2024); 345-358Semina: Ciências Agrárias; v. 44 n. 2 (2024); 345-3581679-03591676-546Xreponame:Semina.
