Composición bromatológica y degradabilidad ruminal in situ de residuos agroindustriales de maracuyá (Passiflora edulis) y plátano (Musa paradisiaca)

The effect of commercial microbial inoculants on the chemical and fermentative characteristics of forage maize silages including passion fruit peel residues was studied. The treatments were: T1: 75% corn fodder and 25% passion fruit peel without commercial inoculum, T2: 75% corn fodder and 25% passion fruit peel with commercial inoculum (All Sill®), T3: 75% corn fodder and 25% passion fruit peel with commercial inoculum (Lacto Silo®). The variables were evaluated: dry matter (DM), organic matter (OM), ash (C), crude fiber (FC) crude protein (PB) after 30 days of storage; the pH and temperature were evaluated every 24 hours, during seven days of post-fermentation aerobic exposure. The experimental design used was randomized with six repetitions. According to the nutritive values ​​of corn forage silage with passion fruit peel, it was observed that there was a slight difference in the ash at 30 days. The temperature and pH at 0, 24, 48, 72, 96, 120, and 144 hours at 30 days of fermentation did not show statistical differences in the treatments according to the probability (P> 0.05), with this we can conclude that the use of bacterial inoculants allows to conserve but not improve the quality of the silage, in that its chemical composition only the ash was influenced by the presence of microbial inoculants, besides that the temperature and pH of the fodder of the corn with residues of passion fruit husk in the silage not was affected by the inclusion of bacterial inoculants.
