Chemical composition and digestibility in vitro of soya, rice, maize, oat and wheat straws


, : Chemical composition and digestibility in vitro of soya, rice, maize, oat and wheat straws. Anuario Tecnico do Instituto de Pesquisas Zootecnicas "Francisco Osorio" 7: 411-431

Digestibility in vitro of organic matter (OM) was 42.7, 42.1, 39.0, 34.9 and 31.3% for soya bean, rice, maize, oat and wheat straws, respectively. Lignin was 13.3, 4.4, 5.3, 7.6 and 9.9% and cellulose 44.2, 34.3, 38.9, 39.8 and 42.4%. The regression equation Y = 26.04 + 1.46X was calculated for maize, oat and wheat straws, where Y is digestibility of OM in vitro (%) and X is the lignin:cellulose ratio. The coefficient of correlation was -0.66 (P <0.01).
