Summary: The aim of this study was to evaluate the voluntary intake and apparent digestibility of dry matter, crude protein, fiber fractions, energy, and the nitrogen balance of Andropogon gayanus hay at three different stages (56, 84 and 112 days). The statistical design was completely randomized, with three treatments and six replicates. Dry matter, fiber fractions, and energy apparent digestibility were higher (P<0.05) for hay harvested at 56 and 84 days. Crude protein intake and apparent digestibility of A. gayanus hay harvested at 56 days of growth were greater (P<0.05) than the hay harvested at 84 and 112 days. The A. gayanus hay showed the best voluntary intake and digestibility at 56 and 84 days of age.Keywords: forage; nutritive value; sheep.

O delineamento estatístico utilizado foi o inteiramente casualizado com três tratamentos e seis repetições. As digestibilidades aparentes da matéria seca, das frações fibrosas e da energia bruta foram maiores para os fenos colhidos aos 56 e 84 dias (P<0,05). O feno de A. gayanus colhido aos 56 dias apresentou maiores valores de consumo e digestibilidade aparente da proteína bruta (5,22 g/UTM/dia; 55,69%, respectivamente) (P<0,05) em relação aos demais tratamentos que não diferiram entre si (P>0,05). Os valores de consumo e digestibilidade aparente apontam as idades de 56 e 84 dias como as melhores dentre as estudadas para o corte do capim A. gayanus para fenação.Palavras-chave: forragem; ovino; valor nutritivo.Universidade Federal de Goiás2016-10-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/1602610.1590/1089-6891v17i416026Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 17 No. 4 (2016); 482-490Ciência Animal Brasileira / Brazilian Animal Science; v. 17 n. 4 (2016); 482-4901809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/16026/21894https://revistas.ufg.br/vet/article/view/16026/21895http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCavalcanti, André CayôSaliba, Eloísa de Oliveira SimõesGonçalves, Lúcio CarlosRodriguez, Norberto MárioBorges, IranBorges, Ana Luiza da Costa Cruz2025-01-24T20:20:48Zoai:ojs.revistas.ufg.br:article/16026Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2025-01-24T20:20:48Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)false
