The exposure of silages to air during storage and transfer between silos may lead the growth aerobic microorganisms so compromise chemical composition, silage quality, in vitro digestibility. In this study, we simulated re-ensiling check for possible effects relation digestibility dry matter, quality stability. Twenty were made, after 150 d, 15 them opened re-ensiled 12, 24, 48 h air. During period, temperature varied from 9.1 28.9 °C (mean: 18.5 °C). Among parameters evaluated, observed...
Abstract Re‐ensiling of previously ensiled forage has been a common practice in Brazil, and the use inoculants may provide means reducing dry‐matter ( DM ) loss. This study aimed to determine effect re‐ensiling microbial on quality sorghum silage. Treatments were presence/absence an inoculant Lactobacillus plantarum Propionibacterium acidipropionici silage, re‐ensiling, or not, material after 24 h exposure air, these tested factorial 2 × design. Losses due gas, effluent total assessed, as...
