Combinations of bacterial cultures, exogenous enzymes, and yeast-based feed additives and their impact on ruminal microbiome
Our objective was to evaluate the effects of bacteria (Lactobacillus animalis, Propionibacterium freudenreichii, Bacillus lichenformis, Bacillus subtilis, and Enterococcus faecium), enzymes (amylase, hemicellulose, and xylanase), and yeast as additives on the ruminal microbiome. We hypothesized that inclusion of bacteria, enzymes, and yeast would impact butyric bacterial populations. Combined bacteria, enzymes, and yeast increase the relative abundance of specific genera primarily within the Prevotellaceae family, which may explain the increase in butyrate molar proportion observed with ADD.
