Efeito da concentração de bactérias homoláticas na ensilagem de capim-elefante (Pennisetum purpureum cv. Roxo)

Abstract

The research analyzes the effect of the microbiological inoculant in silage of elephant (Pennisetum purpureum cv. Purple) in increasing concentrations of inclusion. The experiment was conducted at the Department of Zootecnia (Animal Science), Universidade Federal Rural da Amazônia (UFRA) consisted of four replications and five treatments (Control, LP/PC4, LP/PC5, LP/PC55, LP/PC6) who were in plastic buckets with lids and sealed with plastic tape, which were weighed weekly until the end of the experiment. Were carried out chemical and bromatological analysis of forage and silages in samples at the opening (Day 0) and the last day of aerobic stabilization (Day 10), beyond the counting of fungi and yeasts in silages to evaluate the quality of the ensiled material. During aerobic data loggers were placed in silos to observe the temperature in the post fermentation There was no significant difference in the chemical composition of silages and mold counts, dry matter recovery, but there was no difference in yeast count at the time of opening. Treatment of higher dosage of the inoculant took more time to break aerobic stability when compared with the control. The use of Lactobacillus plantarum and Pediococcus acidilactici can be recommended, since it improves the stability, but in terms of fermentation and chemical composition, the effects were minimal.
