At the end of the trial, nine rectum fecal samples were randomly selected from each group for bacterial DNA sequencing.<h4>Results</h4>There was no difference among groups about alpha diversity indices (all p>0.05), including ACE, Chao 1, Shannon,Animal bioscienceComparison of rectum fecal bacterial community of finishing bulls fed high-concentrate diets with active dry yeast and yeast culture supplementation.PMC98346603206076320220202048NC31660669YDZJ202203CGZH042Geng CGao KfalseComparison of rectum fecal bacterial community of finishing bulls fed high-concentrate diets with active dry yeast and yeast culture supplementation.<h4>Objective</h4>The objective of this study was to investigate the effects of feeding active dry yeast (ADY) and yeast culture (YC) on fecal bacterial community in finishing bulls fed high-concentrate diets in the same experimental environment.<h4>Methods</h4>Forty-five healthy finishing cattle (Simmental×Chinese Luxi yellow bulls; 24 months; 505±29 kg) were randomly divided into three groups: i) CON group (control group, only fed basal diet), ii) ADY group (fed basal diet + active dry yeast), and iii) YC group (fed basal diet + yeast culture).
