Previous issue date: 2012-03-29 / This study was conducted to evaluate the consumption and digestibility of
dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), total
carbohydrates (TC), non-fiber carbohydrates (NFC) and neutral detergent fiber (NDF) in
sheep fed hay moringa (Moringa oleifera Lam) obtained with four cutting ages (28, 35, 42
and 49 days). We used 20 females Morada Nova breed, with 20kg of live weight,
distributed in a completely randomized design and maintained in metabolism cages. There
was a negative linear effect of age of cutting on DM intake, with an estimated maximum
consumption of 0.67 kg / day for the hay produced at 28 days of cutting. It was also
observed linear behavior, with an estimated maximum consumption 172g/dia, 0.36 kg /
day; 18g/dia, at 35, 42 and 49 days old, for CP, OM and EE, respectively. For NDF,
quadratic effect was found with advancing maturity of the plant. The apparent digestibility
of DM, CP, OM and TC linearly decreased with advancing age of cutting hay Moringa
oleifera. It was concluded that the hay Moringa oleifera showed better nutritional value
after 28 days of cutting / O presente trabalho foi conduzido com o objetivo de avaliar o consumo e as
digestibilidades aparentes de mat?ria seca (MS), mat?ria org?nica (MO), prote?na bruta
(PB), extrato et?reo (EE), carboidratos totais (CHOT), carboidratos n?o fibrosos (CNF) e
fibra em detergente neutro (FDN) em ovinos alimentados com feno de moringa (Moringa
oleifera Lam) obtido com quatro idades de corte (28, 35, 42 e 49 dias). Foram utilizadas 20
f?meas da ra?a Morada Nova, com 20 kg de peso vivo m?dio, distribu?das em um
delineamento inteiramente casualizado e mantidas em gaiolas de metabolismo. Observouse
efeito linear decrescente da idade de rebrota sobre o consumo de MS, estimando-se
consumo m?ximo de 0,67 kg/dia para o feno elaborado aos 28 dias de corte. Tamb?m foi
observada resposta linear decrescente, estimando-se consumos m?ximos de 172 g/dia; 0,36
kg/dia; 18 g/dia, aos 35; 42 e 49 dias de idade, para PB, MO e EE, respectivamente. Para
FDN, encontrou-se efeito quadr?tico com o avan?o da maturidade da planta. As
digestibilidades aparentes de MS, PB, MO e CHOT diminu?ram linearmente com o avan?o
da idade de corte do feno de Moringa ole?fera. Concluiu-se que o feno de Moringa ole?fera
apresentou melhor valor nutritivo aos 28 dias de corte
