Abstract

The present work was done at Instituto de Zootecnia in Nova Odessa county, SP, Brazil, with the aim of evaluating the digestibility coeficients of several nutrients as well as the nutritive value of B. decumbens and B. brizantha hays under three cutting frequencies. The classical methodology for total feaces collection applied to sheep was used. The following average results were obtained: 55.09 and 54.25% of TDN; 47.86 and 52.58g/kg LW.75 of dry matter intake and 26.57 and 28.41g of TDN/kg LW.75 of nutritive value for, B. decumbens and B. brizantha hays, respectvelly. The nutritive value of E. decumbens hay decreased linearly (P <0.05) as plant age increased, but did not vary (P> 0.05) for B. brizantha hay. There was a linear decrease of dry matter intake as plant age of both species increased.
