Estudo da digestibilidade e da correlação entre os nutrientes digestíveis do capim-guatemala (Tripsacum fasciculatum, Trin) e do capim-elefante "napier" (Pennisetum purpureum, Schum) e das silagens de sorgo (Sorghum vulgare, Pers) e de milho (Zea mays, L)

Abstract 

The proximate composition, apparent digestibility and correlations between TDN and digestibility of DM, OM, and energy of Guatemala grass and elephant grass at different stages of growth, and of maize silage and sorghum silage were studied in sheep. With Guatemala grass, digestibility of DM, CP, CF, NFE, ether extract, energy, OM and TDN decreased with increase in DM content. Digestibility and TDN of elephant grass varied significantly with DM content. In maize and sorghum silages, apparent digestibility of DM, CP, CF, NFE, energy, OM and TDN did not show any significant differences, but digestibility of ether extract of maize silage was higher than that of sorghum silage. It was shown that TDN can be estimated from digestibility of DM, OM and energy.
