An Integrated Extension and Education Program to Reduce Mastitis and Antimicrobial Use (Quality Milk Alliance)

This project, the Quality Milk Alliance, focuses on improving the quality of milk produced on dairy farms by reducing the incidence of mastitis.  Mastitis is the most devastating disease affecting adult dairy cattle in the United States, and is the single biggest cause of antimicrobial use in the dairy industry. Despite all our scientific knowledge of prevention and therapy of mastitis, many farms continue to struggle with the adoption of effective mastitis control practices.  The project will develop and implement an intervention that will lead to an extension-based program for the reduction of mastitis and antimicrobial use.  Research is focused on overcoming behavioral barriers while having the flexibility to address the diversity of the U.S. dairy industry.  As the project completed phase one it became clear that the industry has human resource development needs.
