Resumo: | An experiment was conducted in the Sheep Farming Laboratory at the Federal University of Santa Maria to examine the effect of different levels of replacement of sorghum silage with soybean pre-cleaning by-product (SPCB) on nutrient intake, performance and feeding behavior; as well as to undertake an economic analysis of feeding finishing lambs in a feedlot system. The study involved 32 uncastrated Texel × Ile de France crossbred male lambs weaned at 60 days of age. Treatments consisted of diets in which the roughage source (sorghum silage) was replaced with SPCB at the levels of 0, 33.5, 66.5 or 100% (DM basis). A 45:55 roughage:concentrate ratio was used (DM basis). The diets were composed of a roughage feed based on sorghum silage and/or SPCB, and a concentrate consisting of crushed maize, soybean meal and limestone. In addition, mineral salt was freely available to the animals. The lambs were slaughtered upon reaching the pre-established live weight of 35 kg. Intake on a DM basis showed a quadratic response (P < 0.05) in all forms it was evaluated and expressed, except for the NDF fraction, which increased linearly (P < 0.05) with SPCB inclusion. Average daily weight gain was not significantly influenced (P > 0.05) by the different SPCB levels, averaging 292 g/day. As regards the feeding behavior characteristics evaluated, the number of daily feeding bouts increased linearly (P < 0.01) with the SPCB content of the diets. Total feed cost decreased linearly (P < 0.01), whereas the profit per kilogram of gain and profit obtained per day in the feedlot period increased linearly (P < 0.01) with SPCB inclusion. The use of soybean pre-cleaning by-product as the roughage source in the finishing of feedlot lambs proved to be a viable alternative in both the productive and economic terms. |

Trinta e dois cordeiros machos, não castrados, mestiços Texel x Ile de France, foram desmamados aos 60 dias de idade. Os tratamentos consistiram em diferentes níveis de substituição de volumoso (silagem de sorgo) para resíduo da pré-limpeza de soja, nos níveis de substituição de 0%, 33,5%, 66,5% e 100%, com base em MS. Foi utilizado uma relação volumoso: concentrado de 45:55 com base na matéria seca.As dietas foram compostas por volumoso à base de silagem de sorgo e / ou resíduo da pré-limpeza de soja, e o concentrado foi composto por milho moído, farelo de soja e calcário calcítico. Além disso, o sal mineral livre foi incluído na dieta dos animais. Os cordeiros foram abatidos quando atingiram o peso pré-estabelecido de 35 kg de peso vivo. A ingestão baseada no comportamento quadrático (P? 0,05), em todas as formas avaliadas e expressas, incluindo o consumo de FDN que apresentou comportamento linear crescente (P? 0,05) com níveis crescentes de resíduo da pré-limpeza da soja . O ganho de peso médio diário não foi influenciado completo (P> 0,05) pelos diferentes níveis de resíduo da pré-limpeza da soja, com valor médio de 292 gramas por dia.Em relação às características do comportamento ingestivo avaliado, observado-se que o número de aumento de aumento linearmente (P? 0,01) com o aumento do nível de resíduo da pré-limpeza da soja nas dietas. O custo total diminuiu linearmente (P? 0,01 ) enquanto o ganho por kg de ganho e o ganho por dia no período de confinamento aumentaram linearmente (P? 0,01) com o aumento da inclusão de resíduo de soja nas dietas. A utilização de resíduo da pré-limpeza da soja como volumoso para terminação de cordeiros confinados revelados-se uma alternativa viável do ponto de vista produtivo e econômico.UEL2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4152310.5433/1679-0359.2021v42n3Supl1p1797Semina: Ciências Agrárias; Vol. 42 No. 3Supl1 (2021); 1797-1812Semina: Ciências Agrárias; v. 42 n. 3Supl1 (2021); 1797-18121679-03591676-546Xreponame:Semina.
