Resumo: | The objective of this study was to assess the effect of varying levels of sorghum silage replacement with waste from soybean pre-cleaning (WSPC) on the characteristics of carcass and non-carcass components in feedlot-finished lambs. A total of 32 uncastrated, weaned, Texel x Ile de France crossbreed male lambs, at 60 days of age, were used. The treatments consisted of different levels of WSPC replacing roughage (sorghum silage) at 0, 33.5, 66.5, and 100% on a dry matter (DM) basis. For these replacement levels, the inclusion of WSPC in the ration was 0, 150, 300, and 450 g kg-1 DM. A roughage-to-concentrate ratio of 45:55, also on a DM basis, was applied. The roughage component consisted of sorghum silage and/or WSPC, while the concentrate contained corn grits, soybean meal, and calcitic limestone. The lambs were slaughtered upon reaching a live weight of 35 kg. The study found no significant differences (P>0.05) in carcass traits across the different levels of WSPC replacement. Among non-carcass components, however, the proportions of liver, pancreas, thymus, and kidneys increased linearly (P≤0.05) with increasing WSPC in the diet. Regarding the filling of the gastrointestinal tract, the content of the rumen, reticulum, small intestine, and total gastrointestinal content decreased linearly (P≤0.05) with greater WSPC in the diet. Waste from soybean pre-cleaning can replace sorghum silage as roughage in feedlot lamb diets without affecting the characteristics of carcass and non-carcass components. A replacement level of up to 100% (inclusion of 450 g kg-1 DM of the ration) is recommended for diets with a roughage-to-concentrate ratio of 45:55. |

Foram utilizados 32 cordeiros machos, não castrados, cruza Texel x Ile de France, desmamados com 60 dias de idade. Os tratamentos foram constituídos por diferentes níveis de substituição do alimento volumoso (silagem de sorgo) por RPLS em níveis de 0; 33,5; 66,5 e 100% de substituição, em base de matéria seca (MS). Para estes níveis de substituição, a inclusão de RPLS na ração foi 0, 150, 300 e 450 g kg-1 MS. Utilizou-se uma relação volumoso:concentrado de 45:55, com base na matéria seca. As dietas eram compostas por volumoso a base de silagem de sorgo e/ou RPLS, e o concentrado composto por milho desintegrado, farelo de soja e calcário calcítico. Os cordeiros foram abatidos quando atingiram o peso pré-estabelecido de 35 kg de peso vivo. As características das carcaças avaliadas nesse estudo não foram influenciadas (P>0,05) pelos níveis de substituição de silagem de sorgo por RPLS. Quanto às características dos componentes não carcaça, as proporções de fígado, pâncreas, timo e rins aumentaram linearmente (P≤0,05) com o nível de substituição de silagem de sorgo por RPLS nas dietas. Quando avaliado o enchimento do trato gastrintestinal, os conteúdos do rúmen, do retículo, do intestino delgado e o conteúdo gastrintestinal total apresentaram comportamento linear decrescente (P≤0,05) com o aumento de RPLS na dieta. A utilização de RPLS em substituição a silagem de sorgo como alimento volumoso na dieta de cordeiros confinados não altera as características da carcaça e dos componentes não carcaça dos animais, podendo-se recomendar a substituição até o nível de 100% (inclusão de 450 g kg-1 MS da ração), em rações com relação volumoso:concentrado de 45:55.UEL2024-05-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4873810.5433/1679-0359.2024v45n3p749Semina: Ciências Agrárias; Vol. 45 No. 3 (2024); 749-764Semina: Ciências Agrárias; v. 45 n. 3 (2024); 749-7641679-03591676-546Xreponame:Semina.
