Resumo: | This research was carried to investigate the effect of different levels of forage neutral detergent fiber (fNDF) in the diet offered to ewe on the intake and apparent digestibility of the diet and on nitrogen balance. Sixteen adult, non-pregnant and non-lactating Santa Ines ewes, weighting 45.01 ± 5.15 kg, were used. The experimental design used was a 4x4 latin square, with four treatments (8.67%; 17.34%; 26.01% and 34.69% of fNDF) four animals and four periods. The intake of dry matter (DM), organic matter (OM), gross energy (GE), digestible energy (DE), metabolizable energy (ME), crude protein (CP), digestible protein (DP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were influenced positively by the levels of fNDF of the treatments. The apparent digestibility of DM, OM, GE and ADF were influenced by treatments. Nitrogen balances were positive at all levels of forage NDF. This study made it clear that there is a physiological limit to the use of concentrate in diets offered to ewe, being necessary a minimum amount of forage NDF in the diet to reach the maximum efficiency of nutrients use; however, this limit seems to be inferior at the lowest level of fNDF of the current study.KEYWORDS: animal nutrition; metabolism; ruminants. |

Foram utilizadas 16 ovelhas adultas, não gestantes e não lactantes, da raça Santa Inês, com peso vivo de 45,01 ± 5,15 kg, distribuídas em delineamento quadrado latino (4x4), com quatro tratamentos (8,67%; 17,34%; 26,01% e 34,69% de FDNf), 4 animais e 4 períodos, perfazendo 4 quadrados latinos. As variáveis referentes ao consumo de matéria seca (MS), matéria orgânica (MO), energia bruta (EB), energia digestível (ED), energia metabolizável (EM), proteína bruta (PB), proteína digestível (PD), fibra em detergente neutro (FND) e fibra em detergente ácido (FDA) bem como os coeficientes de digestibilidade aparente da MS, MO, EB e FDA foram influenciados positivamente pelos níveis crescentes de FDNf dos tratamentos. O balanço de nitrogênio foi positivo em todos os níveis de FDNf. O trabalho evidenciou que existe um limite fisiológico para a utilização de concentrado na dieta de ovelhas, sendo necessária uma quantidade mínima de FDNf para maior eficiência no aproveitamento dos nutrientes; no entanto, esse limite parece ser inferior ao nível mais baixo de FDNf do presente estudo.PALAVRAS-CHAVE: metabolismo; nutrição animal; ruminantes.Universidade Federal de Goiás2012-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/948110.5216/cab.v13i1.9481Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 1 (2012); 33-40Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 1 (2012); 33-401809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/9481/10577https://revistas.ufg.br/vet/article/view/9481/10579https://revistas.ufg.br/vet/article/view/9481/12344Macedo Junior, Gilberto de L.de Sousa, Luciano Fernandesde Godoi, Fernanda NascimentoPerez, Juan R.
