In this episode of The Moos Room, Brad  discusses a University of Minnesota study examining how these three rearing systems influence microbial communities, growth, and the transition through weaning.\nIndividually housed calves and calves raised in groups of six received similar diets and developed similar gut microbiomes, suggesting that calf-to-calf contact alone had little influence on microbial diversity. Dam-reared calves, however, developed distinct microbial communities and had the highest average daily gains. Their lower microbial diversity before weaning did not correspond with poorer growth.\nBrad explores how access to milk, contact with adult cows, and exposure to solid feeds may help explain these differences. Within three to four days after weaning, microbial diversity increased in dam-reared calves as they transitioned away from milk, although some differences among rearing systems remained. Because the systems differed in several ways, the findings reflect the combined effects of diet, environment, and maternal contact.\nThe episode also includes updates on fall grazing, virtual fencing, and ongoing calf research at the West Central Research and Outreach Center, plus a preview of Brad’s upcoming trip to Sweden.\nQuestions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!\nLinkedin -> The Moos Room\nTwitter -> @UMNmoosroom and @UMNFarmSafety\nFacebook -> @UMNDairy\nYouTube -> UMN Beef and Dairy and UMN Farm Safety and Health\nInstagram -> @UMNWCROCDairy\nExtension Website\nAgriAmerica Podcast Directory ","thumbnail_url":"https://img.transistorcdn.com/EIqekZJUCM-mbRXSkEsLe4I4Erj3AsT3id_xoW-dk6k/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzE0MTkwLzE2OTc0/ODIyODEtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
