PS8-26. Residual Feed Intake Phenotype Modulates Growth Performance and Ruminal Microbiome Responses to a Bacillus-based Direct-fed Microbial in Beef Steers.
Dietary supplementation with direct-fed microbials may improve cattle performance through rumen microbiome modulation; however, responses are inconsistent and may depend on host feed efficiency phenotype. This study evaluated the effects of a Bacillus-based direct-fed microbial (DFM) on growth performance and the rum...
