Organic dairy farms in the United States face a unique challenge when it comes to mastitis management, as synthetic antibiotics are not allowed for use in organic production. However, if a cow is sick and organic therapies do not work, antibiotics must be used to treat disease. Organic regulations in the United States mandate that any organic cow that receives antibiotic therapy forfeits her organic status. Many different mastitis mitigation strategies on organic dairy farms have been reported in the scientific literature but most studies were completed in the Midwest and Northeast. In the South, especially the Southeast, dairy farmers must contend with high heat and humidity for a longer period of the year and the consequent effects that heat stress has on dairy cattle. I will discuss the current scientific literature evaluating organic dairy farms in the South, from mastitis prevalence to breeding for a more mastitis resistant cow. Organic dairy farmers can follow most of the National Mastitis Council’s 10-point control plan; this and other considerations unique to organic dairy farms will be covered during this session.
