Relação entre a Composição Química e a Degradabilidade In Situ da Matéria Seca e da Fibra em Detergente Neutro da Fração Volumosa de Híbridos de Milho1

The chemical composition and in situ dry matter (DM) and neutral detergent fiber (NDF) of bulky fraction (stall and sheets) degradation of 28 corn hybrids in 1996, and 21 hybrids, in 1997, were studied to establish the correlation among th e analyzed factors. From the 21 hybrids selected in 1997, 13 were part of the experiment in 1996. The model
