Resumo: | The objective was to evaluate the effects of the inclusion of increasing levels of extruded roughage (Urochloa brizantha) to replace corn silage on consumption, digestibility, ingestive behavior and blood metabolites in sheep. Twenty Santa Inês ewes over three years of age and an average body weight of 55.8 kg were used. A completely randomized design was carried out with four treatments and five repetitions, and the results were submitted to a regression study at 95% probability. The treatments used were different levels of inclusion of the extruded roughage Foragge® 65% (F) replacing corn silage (S), being: 20% Foragge® and 80% corn silage (20% F: 80% S ); 40% Foragge® and 60% corn silage (40% F: 60% S); 60% Foragge® and 40% corn silage (60% F: 40% S) and 80% Foragge® and 20% corn silage (80% F: 20% S). The animals were kept in individual metabolic cages, equipped with feeders, salt shakers and drinking fountains. A digestibility study was carried out, allowing the evaluation of dry matter intake (DMI), digestibility, ingestive behavior and blood metabolites. The DMI showed a positive linear response to the inclusion of extruded roughage, as well as water consumption, fecal weight and efficiency of ingestion, rumination and chewing, without altering digestibility. Blood urea levels showed a quadratic response to the inclusion of extruded roughage. It is concluded that the partial replacement of corn silage by Foragge® in 40%, occurred in the 40F: 60S treatment, is very positive, gained in efficiency, work and productivity. |

Foram utilizadas 20 ovelhas da raça Santa Inês com idade superior a três anos e peso corporal médio de 55,8 kg. Foi realizado um delineamento inteiramente casualizado com quatro tratamentos e cinco repetições, sendo os resultados submetidos ao estudo de regressão (P<0,05). Os tratamentos utilizados foram diferentes níveis de inclusão do volumoso extrusado comercial Foragge® 65% (F, Nuttrata Nutrição Animal©, Itumbiara-GO, Brasil) em substituição à silagem de milho (S), sendo: 20% de Foragge® e 80% de silagem de milho (20%F:80%S); 40% de Foragge® e 60% de silagem de milho (40%F:60%S); 60% de Foragge® e 40% de silagem de milho (60%F:40%S) e 80% de Foragge® e 20% de silagem de milho (80%F:20%S). Os animais foram mantidos em gaiolas metabólicas individuais, dispostas de comedouros, saleiro e bebedouros. Realizou-se estudo de digestibilidade, permitindo avaliar o consumo de matéria seca (CMS), digestibilidade, comportamento ingestivo e metabólitos sanguíneos. O CMS apresentou resposta linear positiva à inclusão do volumoso extrusado, assim com o consumo de água, peso das fezes e eficiência de ingestão, ruminação e mastigação, sem alterar a digestibilidade. Os níveis de ureia sanguínea apresentaram resposta quadrática à inclusão do volumoso extrusado. Conclui-se que a substituição parcial da silagem de milho pelo Foragge® em até 80% é recomendada, não observando-se distúrbios metabólicos ou alterações negativas na digestibilidade da matéria seca e elevação do consumo.
