The effect of a multi-carbohydrase enzyme and yeast-derived product on intestinal microbiome structure, activity, and gut function of turkeys

The effect of a multi-carbohydrase (E) and its combination with an enzymatically modified yeast cell wall (Y) on the ileal cecal microbiota gut function turkeys was studied. experimental diets, including control (C), C + E, E Y, were fed to seven replicate pens four birds from 22 56 days age. addition Y resulted in significant decrease relative abundance Firmicutes increase Actinobacteria digesta. A not followed by Ruminococcaceae, one butyrate-producing bacteria. This coincided significantly increased concentration butyrate digesta proportion within total short-chain fatty acids (SCFA). As opposed ileum, or did affect ceca. higher content SCFA than ileum would reflect differences microbial activities both compartments, possible absorption ileum. Overall, positive effects enzyme bioactive supplements bacterial communities appeared be more pronounced small intestine.
