ResumenThe objective of the present study was to investigate the effects of a yeast hydrolyzate of Saccharomyces cerevisiae, obtained after ethanol production from sugarcane biomass, on in vitro rumen fermentation in Rusitec fermenters inoculated with rumen microorganisms from sheep. Four fermenters were given daily 30 g of diet dry matter (DM: 1:1 alfalfa hay: concentrate), and half of them were supplemented daily with 5 mL of yeast hydrolyzate in a cross-over experimental design with two 14-day incubation periods. Supplementing with yeast hydrolyzate did not affect (P=0.90) total volatile fatty acid (VFA) production, lactate concentrations, DM and neutral detergent fibre degradability or fibrolytic enzyme activity. Compared with the unsupplemented fermenters, yeast hydrolyzate treatment increased (P < 0.001) NH3-N concentrations and molar proportions of propionate and butyrate at the expense of acetate, and decreased (P < 0.001) acetate/propionate ratio. In addition, yeast hydrolyzate supplementation tended (P< 0.07) to reduce methane/total VFA ratio and to increase microbial growth in the liquid phase of the fermenters. The results indicate that yeast hydrolyzate may be a useful dietary additive for ruminants, because it promoted a shift in fermentation toward propionate production, reduced the methane/total VFA ratio and increased microbial growth.
