Elephantgrass (Pennisetum purpurem, Schum) silage under effect of bacterial inoculants

Abstract

This study was carried out to evaluate the effects of bacterial inoculated king grass for silage production with laboratory silos ( 5 liters plastics buclets with valve for gas scape). The elephantgrass was cutted for uniformization and adubation and after 60 days (14,% DM and 9,7% PB) was cutted and sliced at 2cm lenght particle and the treatments were: control (C), Sil-All (SA) inoculant (Streptococcus faecium, Pediococcus acidilactici, Lactobacillus plantarum, amylase, cellulase e hemicellulase).; Pioneer 1174 (P) inoculant (Streptococcus faecium e Lactobacillus plantarum) SiloBac (SB) inoculant (Lactobacillus plantarum, Streptococcus faecium e Lactobacillus sp. ). After 123 of fermentation, the silos were opened and was the fermentation was characterized and determined dry matter losses and in vitro dry matter digestibility. Amoniacal nitrogen, lactic acid, acetic acid, butiric acid, dry matter losses and in vitro dry matter digestibility did not suffer influence of treatments. C and SA treatments produced silagens with higher pH.
