Resumo: | The objective of this work was to evaluate the use of extruded roughage containing different additives, on nutritional and physiological parameters of sheep. Twenty non - pregnant ewes were used, adults with an average weight of 68 kg. The animals received five treatments containing extruded roughage with different additives (essential oils, virginiamycin, tannin, unpurified inactive yeast and purified inactive yeast). The experimental design was a randomized block design with five treatments and eight replications. The means were compared by the SNK test with significance level of 5% of probability. The following variables were evaluated: dry matter and neutral detergent fiber intake and digestibility; dry matter intake as a function of body and metabolic weight; ingestive behavior; physiological parameters and ruminal pH. No statistical difference was observed due to the inclusion of additives, for dry matter and neutral detergent fiber intake and digestibility, ingestive behavior, feed efficiency, respiratory rate, heart rate, rectal temperature and ruminal pH. The treatment with purified yeast showed the highest dry matter intake as a function of body and metabolic weight. There was a quadratic effect on pH depending on the time of collection, being lower in the first 4 hours after the meal, that is, the use of additives shows a positive response in rumen fermentation due to the reestablishment of the pH value. The use of additives influenced the dry matter intake by the sheep, which is greater when the additive inactive purified yeast is used. The additives were also efficient in maintaining ruminal pH and apparent dry matter digestibility. |

Foram utilizadas 20 ovelhas não gestantes, adultas, com peso médio de 68 kg. Os animais receberam cinco tratamentos contendo volumoso extrusado com diferentes aditivos (óleos essenciais, virginiamicina, tanino, levedura inativa não purificada e levedura inativa purificada). O delineamento foi em blocos casualizados, com cinco tratamentos e oito repetições. As médias foram comparadas pelo teste SNK com nível de significância de 5% de probabilidade. Avaliou-se o consumo e digestibilidade da matéria seca e fibra em detergente neutro, consumo de matéria seca em função de peso corporal e metabólico, comportamento ingestivo, parâmetros fisiológicos e pH ruminal. Não foram observadas diferenças estatísticas em função da inclusão de aditivos para consumo e digestibilidade da matéria seca, fibra em detergente neutro e digestibilidade de fibra em detergente neutro, comportamento ingestivo, eficiência de alimentação, frequência respiratória, frequência cardíaca, temperatura retal e pH ruminal. O tratamento com levedura purificada apresentou o maior consumo de matéria seca em função do peso corporal e metabólico. Houve efeito quadrático sobre o pH em função do horário de coleta, sendo menor nas primeiras 4 horas após a refeição, ou seja, o uso de aditivos apresenta resposta positiva na fermentação ruminal devido ao reestabelecimento do valor de pH. O uso de aditivos influenciou o consumo de matéria seca pelas ovelhas, sendo este maior quando utilizado o aditivo levedura inativa purificada. Os aditivos foram eficientes também na manutenção do pH ruminal e digestibilidade aparente da matéria seca.Universidade Federal de Minas Gerais2020-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/2060610.35699/2447-6218.2020.20606Agrarian Sciences Journal; Vol. 12 (2020); 1-9Caderno de Ciências Agrárias; v. 12 (2020); 1-92447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGporhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/20606/19703https://periodicos.ufmg.br/index.php/ccaufmg/article/view/20606/19704Copyright (c) 2020 Caderno de Ciências Agráriashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Karla AlvesAssis, Tamires SoaresSousa, Luciano Siqueira, Marco Tulio Souza, Amanda Menezes de Macedo Júnior, Gilberto de Lima2022-07-28T12:42:31Zoai:periodicos.ufmg.br:article/20606Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-07-28T12:42:31Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false |
