Tired of waiting for mastitis culture results to come back and, when they do, the result is “no growth”? About 40 percent of clinically abnormal milk samples tested with traditional bacterial culture come back with a “no growth” result, often leaving dairy producers right where they started – with a mastitic cow and no diagnosis for accurate treatment.

Changes in dairy herd management, primarily herd expansion, have turned mycoplasma mastitis into an emerging disease. The U.S. National Animal Health Monitoring Service conducted a recent survey, which estimated during any single year, 20 percent of 500-plus-cow herds in the U.S. will have a positive mycoplasma mastitis bulk tank.
