Resumo: | This study investigates the effect of different compositions of high-grain diets on lamb termination on performance and changes in ingestive and physiological behavior. Twenty-four male lambs were used, with no defined racial pattern, with an average initial weight of 20.9 kg, at 6 months of age. Three diets containing different proportions of concentrate and roughage (100:0, 80:20, and 60:40) were supplied, with the concentrated portion of the diets being composed 85% whole-grain corn and 15% commercial pelletized supplement. There was no effect (P > 0.05) of the test diets for the consumption of dry matter (MS), mineral matter (MM), neutral detergent fiber (FDN), total carbohydrates (CT) and total digestible nutrients (NDT), expressed in g/day and % of live weight. The averages of total and daily weight gain and slaughter weight were similar (P > 0.05) between diets, registering daily weight gain of 0.302, 0.254 and 0.259 g/day with 100, 80 and 60% of concentrated, respectively. Lambs fed exclusively with concentrate decreased the time dedicated to rumination (P ≤ 0.05), and showed greater efficiency in feeding (EAL) and rumination (ERU). The animals in the diet without roughage showed marked variation in temperature in the rumen region, while lambs from the diets with 80 and 60% concentrate showed changes in temperatures close to the same evaluation period. All evaluated diets showed satisfactory performance, and despite the changes observed in the animals ingestive behavior, these were not sufficient to impair the lambs performance indices. |

Se utilizaron veinticuatro corderos machos, sin patrón racial definido, con un peso inicial promedio de 20,9 kg, a los 6 meses de edad. Se elaboraron tres dietas con diferentes proporciones de concentradas y voluminoso (100:0, 80:20 y 60:40), estando la porción concentrada de las dietas compuesta por grano de maíz integral asociado al suplemento proteína-mineral-vitamínico. No hubo efecto (P> 0.05) de las dietas de prueba para el consumo de materia seca (MS), materia mineral (MM), fibra detergente neutra (FDN), carbohidratos totales (CT) y nutrientes digestibles totales (NDT), expresado en g/día y % de el peso vivo. Los promedios de ganancia de peso total y diaria y peso de faena fueron similares (P> 0.05) entre dietas, registrándose ganancia de peso diaria de 0.302, 0.254 y 0.259 g/día con 100, 80 y 60% de concentrado, respectivamente. Los corderos alimentados exclusivamente con concentrado disminuyeron el tiempo dedicado a la rumia (P ≤ 0.05), y mostraron mayor eficiencia en la alimentación (EAL) y rumia (ERU). Los animales en la dieta sin voluminoso mostraron marcada variación de temperatura en la región del rumen, mientras que los corderos de las dietas con 80 y 60% de concentrado mostraron cambios en las temperaturas cercanas al mismo período de evaluación. Todas las dietas evaluadas mostraron un desempeño satisfactorio y, a pesar de los cambios observados en el comportamiento ingestivo de los animales, estos no fueron suficientes para afectar los índices de desempeño de los corderos.Neste estudo investiga-se o efeito de diferentes composições de dietas de alto grão na terminação de cordeiros sobre o desempenho e alterações no comportamento ingestivo e fisiológico. Foram utilizados 24 cordeiros machos, sem padrão racial definido com peso inicial médio de 20,9 kg, com 6 meses de idade. Foram elaboradas três dietas com diferentes proporções de concentrado e volumoso (100:0, 80:20 e 60:40), sendo a porção concentrada das dietas compostas por grão de milho inteiro associando ao suplemento protéico-mineral-vitamínico. Não houve efeito (P > 0,05) das dietas teste para os consumos de matéria seca (MS), matéria mineral (MM), fibra em detergente neutro (FDN), carboidratos totais (CT) e nutrientes digestíveis totais (NDT), expressos em g/dia e % de peso vivo. As médias de ganho de peso total e diário e peso de abate foram semelhantes (P > 0,05) entre as dietas, registrando-se ganho de peso diário de 0,302, 0,254 e 0,259 g/dia com 100, 80 e 60% de concentrado, respectivamente. Os cordeiros alimentados exclusivamente com concentrado diminuíram o tempo dedicado a ruminação (P ≤ 0,05), e apresentaram maior eficiência na alimentação (EAL) e ruminação (ERU). Os animais da dieta sem volumoso apresentaram acentuada variação de temperatura na região do rúmen, enquanto que cordeiros das dietas com 80 e 60% de concentrado apresentaram alterações de temperaturas próximas no mesmo período de avaliação. Todas as dietas avaliadas apresentaram desempenho satisfatório, e apesar das alterações observadas no comportamento ingestivo dos animais, essas não foram suficientes para prejudicar os índices de desempenho dos cordeiros.Research, Society and Development2020-09-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/844310.33448/rsd-v9i10.8443Research, Society and Development; Vol. 9 No. 10; e2559108443Research, Society and Development; Vol. 9 Núm. 10; e2559108443Research, Society and Development; v. 9 n. 10; e25591084432525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/8443/7579Copyright (c) 2020 Hélia Maria de Souza Leite; Nayane Valente Batista; Allison Ferreira de Lima; Leandro Alves da Silva; Jéssica Taiomara Moura Costa Bezerra de Oliveira; Salenilda Soares Firmino; Maria Raquel Lopes Silva; Patrícia de Oliveira Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLeite, Hélia Maria de SouzaBatista, Nayane ValenteLima, Allison Ferreira deSilva, Leandro Alves daOliveira, Jéssica Taiomara Moura Costa Bezerra deFirmino, Salenilda SoaresSilva, Maria Raquel Lopes Lima, Patrícia de Oliveira2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8443Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:54.840300Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
