Mastitis in First-lactation Organic Dairy Cows

This eOrganic webinar took place on January 18, 2023.

This webinar will provide a description of microorganisms leading to intramammary infections in first-lactation organic dairy cows, their risk factors and their relationship with udder health on the following lactation. The findings of a NIFA OREI funded research project provide important information that could be used to develop tailored mastitis control plans for first-lactation organic dairy cows.
