The use of antibiotic dry cow therapy at the end of lactation is a standard part of mastitis control programs, and in the United States it is highly adopted. In fact, USDA National Animal Health Monitoring Survey data shows more than 80 percent of US dairy herds treat 100 percent of the quarters of their cows at the end of dry off. And almost all herds treat a majority of all quarters.
However, today we are undergoing a reexamination of the use of antibiotics on dairy farms with the goal of using antibiotics responsibility and for only animals that will benefit.
UW-Extension Milk Quality Specialist Pam Ruegg has developed a four part video series The Use of Dry Cow Therapy on Dairy Farms to answer the question “Do all farms benefit from dry cow therapy?” In Part 2: The Science Behind Selective Dry Cow Therapy, Dr. Ruegg explains the concept of selective dry cow therapy to use dry cow treatment in cows with infection in known quarters and how to identify those quarters.
She also shares the FDA-approved Drugs for Intramammary Use in Dry Cows.
The Science Behind Selective Dry Cow Therapy is one video of four in a new video series The Use of Dry Cow Therapy on Dairy Farms. Other videos include:
- Part 1: Why is dry cow therapy recommended?
- Part 2: The Science Behind Selective Dry Cow Therapy
- Part 3: What herds may benefit from selective dry cow therapy?
- Part 4: How should dry cow therapy be administered?
UW-Milk Quality promotes an integrated, team-based approach to best manage udder health and milk quality. Producing high quality milk is not a one-person job. It takes farmers and their local dairy advisors to be able to evaluate, manage and improve milk quality. At UW-Milk Quality, we develop tools and resources to help dairy producers meet their milk quality goals and increase farm profitability.
