Resumo: | The objective of this study was to evaluate the use of extrused roughage on nutritional and metabolic parameters in sheep. Eighteen 3-year-old sheep in metabolic cages were randomly assigned to two treatments: corn silage and extruded roughage. Dry matter intake (DMI) and water intake were calculated as the difference between offered feed and orts left. Ruminal movement was assessed through auscultation of the rumen for five minutes, glycemia and other metabolites through blood collection by jugular venipuncture, and feeding behavior by observation every 5 minutes for 24 hours. DMI per animal, both as a percentage of live weight and in relation to metabolic weight, was higher for animals fed extrused roughage. The extrused roughage treatment also resulted in reduced ruminal movement and higher dry matter digestibility (DMD), glycemia and drinking water intake. Animals fed with extrused roughage reduced the time of rumination and total chewing, thus increasing ingestion, chewing and rumination efficiency. Blood concentrations of glucose and urea were higher in animals fed extrused roughage, while cholesterol concentration was lower. We conclude that the use of extrused roughage promotes improvement in the nutritional parameters of sheep by increasing DMI and DMD, and reducing chewing and rumination times, without causing disorders in energy and protein metabolism. |

Para isso utilizou-se dezoito ovelhas com idade média de 3 (três) anos, alocadas em gaiolas metabólicas, distribuídas em delineamento inteiramente casualizado em dois tratamentos: silagem de milho e volumoso extrusado. O CMS e consumo de água foram calculados pela diferença entre ofertado e sobra. A movimentação ruminal foi obtida através de auscultação do rúmen por cinco minutos, a glicemia e os metabólitos energéticos e proteicos através de coleta de sangue por venopunção jugular, e o comportamento ingestivo por observação a cada 5 minutos durante 24 horas. O CMS quando expresso em porcentagem do peso corporal e em relação ao peso metabólico foi maior para o tratamento com volumoso extrusado em todas as unidades estudadas, o que se deve a melhor digestibilidade da matéria seca da ração. A movimentação ruminal foi menor e a digestibilidade da matéria seca (DMS), glicemia e o consumo de água bebida maior para o tratamento com o volumoso extrusado. Os animais alimentados com o volumoso extrusado reduziram o tempo de ruminação e mastigação total, consequentemente aumentaram a eficiência de ingestão, ruminação e mastigação total. A concentração sanguínea de glicose e ureia foi maior para o tratamento com o volumoso extrusado, enquanto a concentração do colesterol foi menor. Conclui-se que o uso do volumoso extrusado promove melhoria nos parâmetros nutricionais de ovinos, aumentando CMS e DMS, e reduzindo tempos de ruminação de mastigação, sem provocar transtornos no metabolismo energético e proteico.UEL2018-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3053910.5433/1679-0359.2018v39n4p1795Semina: Ciências Agrárias; Vol. 39 No. 4 (2018); 1795-1804Semina: Ciências Agrárias; v. 39 n. 4 (2018); 1795-18041679-03591676-546Xreponame:Semina.
