Meta-análise da inoculação com lactobacillus buchneri na ensilagem de cana-de-açúcar

Abstract

The main problem in sugarcane silage is the alcoholic fermentation carried out by yeasts during the storage period. Thus, the objective of this study was to evaluate the effect of inoculation of Lactobacillus buchneri on sugarcane silages quality. A meta-analysis was performed with data collected from experiments carried out the last 10 years. Initially, 70 papers were found between articles, theses and dissertations that worked with L. buchneri on sugarcane silages. The studies that did not compare the inoculated silage with silage without inoculant or studies without measures of variance were discarded. Eight studies were considered for the effect on aerobic stability, twelve for ethanol production, ten for dry matter loss and only four for milk production. Significant difference was found for aerobic stability and ethanol production. There was no difference for dry matter loss and milk production. The use of additive can reduce overall losses in the production system. It may be necessary to associate more than one strain of L. buchneri or with another species of bacteria to confirm other advantages such as the reduction of losses in DM verified by some authors.
