Resumo: | The objective was to evaluate the nutritional parameters, feeding behavior and energy and protein metabolism of sheep fed with different types of extruded roughage. Twenty adult Santa Inês sheep were placed in individual metabolic cages. The experiment lasted 21 days: fifteen days of adaptation and six days of data collection. The treatments were diets containing corn silage or extruded roughage with different contents of Uruchloa brizantha in its composition (52.5%, 60% and 65%). An experiment was carried out to determine dry matter intake (DMI) and apparent dry matter digestibility (DMD). Blood collection for analysis of blood metabolites was performed through jugular venipuncture. Feeding behavior was assessed for 24 hours. A completely randomized design was used, with four treatments and five replications. The treatment means were compared using the Tukey test at a 5% level of significance. The DMI (kg / day) and in relation to body weight (BW%) and water intake (liters / day) were higher (P <0.05) in animals that received extruded roughage. The fecal weight showed the same response pattern, and did not change the fecal score. The time spent in ingestion, rumination and chewing were shorter (P <0.05) for the animals that received exclusively corn silage, but their respective efficiencies were lower when compared to the extruded roughage. Blood urea levels were lower for animals that received corn silage (P <0.05). Therefore, the use of extruded roughage with an Uruchloa brizantha content of up to 65% can replace corn silage without causing metabolic disorders for sheep. |

Vinte ovelhas Santa Inês, adultas, foram alocadas em gaiolas metabólicas individuais. O experimento teve duração de 21dias: quinze dias de adaptação e seis dias de coleta de dados. Os tratamentos foram dietas contendo silagem de milho ou volumoso extrusado com diferentes teores de Uruchloa brizantha em sua composição (52,5%, 60% e 65%). Foi realizado ensaio para determinar o consumo de matéria seca (CMS) e digestibilidade aparente da matéria seca (DMS). A coleta de sangue para análise dos metabólitos sanguíneos foi realizada através de venopunção jugular. O comportamento ingestivo foi avaliado durante 24 horas. Utilizou-se o delineamento inteiramente ao acaso, com quatro tratamentos e cinco repetições. As médias dos tratamentos foram comparadas pelo teste de Tukey ao nível de 5% de significância. O CMS (kg/dia) e em relação ao peso corporal (PC%) e o consumo de água e (litros/dia) foram superiores (P<0,05) nos animais que receberam volumoso extrusado. O peso das fezes apresentaram o mesmo padrão de resposta, e não alteraram o escore fecal. O tempo gasto em ingestão, ruminação e mastigação foram menores (P<0,05) para os animais que receberam exclusivamente silagem de milho, porém suas respectivas eficiências foram menores, quando comparadas com o volumoso extrusado. Os níveis de ureia sanguínea foram menores para os animais que receberam silagem de milho (P<0,05). Portanto, a utilização de volumoso extrusado com teor de Uruchloa brizantha de até 65% pode substituir a silagem de milho sem causar transtornos metabólicos para ovinos.Universidade Federal de Minas Gerais2020-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/2581010.35699/2447-6218.2020.25810Agrarian Sciences Journal; Vol. 12 (2020); 1-11Caderno de Ciências Agrárias; v. 12 (2020); 1-112447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGporhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/25810/20523https://periodicos.ufmg.br/index.php/ccaufmg/article/view/25810/20524Copyright (c) 2020 Caderno de Ciências Agráriashttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAraujo, Carolina MoreiraOliveira, Karla AlvesMacedo Junior, Gilberto de Lima Silva, Simone Pedro daSilva, Débora Adriana de Paula 2022-07-28T15:24:36Zoai:periodicos.ufmg.br:article/25810Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-07-28T15:24:36Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false |
