Bedding strategies that promote udder health and milk quality by fostering a beneficial microbiome on organic dairy farms (9/1/18-present). website I am co-PI with John Barlow (UVM Animal and Veterinary Sciences) on this project funded by the USDA-NIFA Organic Research Education Initiative. The goals of this research project are to identify economically sustainable bedding management strategies that reduce mastitis risk and promote udder health and milk quality on organic dairy farms, and to develop best management practice recommendations addressing udder health microbiological risks and benefits of common winter housing strategies, with a focus on "bedded-pack" loose-housing systems.
