Abstract

This study confirms previous findings of the effectiveness of post-milking teat disinfection in reducing the incidence of IMI caused by the common mastitis-causing pathogens in New Zealand, and presents the first results of a controlled study examining pre-milking teat spraying undertaken in New Zealand commercial dairy herds.
