Descripción

The use of bacterial additives in forage sila ges with low content of dry matter prevents undesirable fermentation and reduces losses by gases (P G) and effluents (PE) during the ensiling process . This study aimed to evaluate the fermentation parameters, chemical composition and in vitro digestibility of silage of Urochloa brizantha cv. Xaraés produced with bacterial additive. The inoculant contained the following strains: Propionibacterium acidipropionici + Lactob acillus plantarum; Lactobacillus buchnari; Propionibacterium acipropionici + commercial enzymes and Lactobacillus plantarum and Pediococcus pentosaccus , at 0, 25, 50, 75, 100, and 125% of the re commended level for sugarcane (2 g ton -1 ). The experiment was a completely randomized design with four replications, and six levels of inoculant (0, 25, 50, 75, 100, and 125%). There was a quadratic relati onship between the inoculant addi tion and the leve ls of pH, PE, DMIVD, NDF, ADF and LIG of the silage. PG and MM in creased linearly with the addition of inoculant. The N-NH 3 , DM, CP, CEL, HEM and EE were not affected by the inoculant. Bacterial additive at 50% provided increased DMIVD. Appropriat e values were found for pH and NH 3.
