He digs into the role of biting flies in BLV transmission, highlighting research showing that nearly all previously negative cows became suspect or positive after just one summer on pasture.\nThe discussion covers:\nHow BLV spreads within herds.\nThe economic and animal health impacts of infection.\nManagement strategies like testing, culling, colostrum protocols, and breeding decisions.\nWhy fly control may be one of the most important tools for reducing BLV spread in grazing herds.\nTune in to hear how the UMN Morris dairy herd is tackling this challenge, what the research says about seasonality and transmission, and what steps farmers can take to manage BLV on their own operations.\n\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}
