Supplementation with Bacillus -based direct-fed microbials for developing beef heifers: impacts on fecal and vaginal microbiome, growth, and reproductive performance

Abstract This 2-year study evaluated the effects of Bacillus-based direct-fed microbial (DFM) supplementation on fecal and vaginal microbiomes, growth, and reproduction of beef heifers. On day 0 (30 days after weaning), Brangus crossbred beef heifers (n = 64 per year) were strati...

Supplementation of a Bacillus -based DFM mixture on growth performance, methane emissions, microbiome, and metabolome in backgrounding beef heifers

Abstract Direct-fed microbials (DFM) have been used to improve livestock production efficiency and reduce environmental impact. Spore-forming bacteria such as Bacillus spp. present handling and processing advantages for use as a DFM; however, more information is needed about thei...
