Abstract

The purpose of this work was to evaluate the effect of wilting and biological additive amendment on chemical composition, fermentation and ruminal degradability of Arachis pintoi cv Belmonte silage. The following treatments were analysed: T1- Arachis pintoi cv Belmonte fresh forage; T2 - Arachis pintoi cv Belmonte fresh forage plus bacterial additive added to the forage prior to the ensilage; T3- Arachis pintoi cv Belmonte wilted by the sun for 4 hours; T4- Arachis pintoi cv Belmonte wilted by the sun plus bacterial additive. The degradability assay was carried out using three rumen-fistuled steers. The biological additive did not affect the chemical composition of silages, in situ degradability of nutrients DM, NDF and CP and of silage fermentation. However, the wilting treatments of the silages increased DM, CP, hemicelulose and decreased N-NH3 concentration, pH value, degradability of soluble fraction €œa€ from DM NDF and CP. The analysed characteristics suggest that Arachis pintoi cv Belmonte could satisfactorily preserve the forage quality if wilted by the sun during 4 hours, after harvested.
