General Session 1:

The Five-Point Mastitis Control Plan – Past, Present and Future


10:15 a.m. – The Five-Point Mastitis Control Plan – A Revisory Tutorial!
Eric Hillerton, Massey University, Cambridge, New Zealand

For nearly 50 years of improvement in udder health, the practice of the Five-Point Mastitis Control Plan has been an essential foundation. This talk will explore where the plan came from – its basis in theory, on-farm testing and validation; why it is necessary; and a little on how it came to be, including the characters involved.


10:50 a.m. – Five Points to Revise the Five-Point Mastitis Control Plan
Christian Scherpenzeel, GD Animal Health, Deventer, the Netherlands

Several new developments in bovine udder health will be highlighted as inspiration to revise the Five-Point Mastitis Control Plan. These developments include the increased knowledge of the normal and abnormal intramammary microbiome of the bovine mammary gland, the increased understanding of the immune-biology of the mammary gland, particularly during late gestation and early lactation, and finally the changing perspectives on antimicrobial use during the dry period of dairy cows.


11:25 a.m. – Dairy Customers and Consumers are Asking ‘What?!?’ About Udder Health?
Jamie Jonker, National Milk Producers Federation, Arlington, Virginia, USA

Dairy customers and consumers are asking more questions and making more demands about how milk is produced. Many questions and demands focus on milk quality and antimicrobial use – which is really “udder health.” So, we’ll explore how udder health fits into the future reality of milk production in the United States.

The Five-Point Mastitis Control Plan – Celebrating the Consistency of Application (split session)
Moderator: David A. Reid, Rocky Ridge Dairy Consulting LLC, Hazel Green, Wisconsin, USA


2:00 p.m. – The History of the National Dairy Quality Awards Program and Its Impact on Milk Quality
Corey Geiger, Hoard’s Dairyman, Fort Atkinson, Wisconsin, USA

For 24 years, the National Dairy Quality Awards program has set the bar by honoring the nation’s top milk quality herds. By recognizing these leading dairy herds, milk quality becomes top of mind and collectively dairy farmers produce higher quality milk each year.


2:20 p.m. – Practices that Enhance Udder Health – The Little Things that Make a Big Difference
David A. Reid, Rocky Ridge Dairy Consulting LLC, Hazel Green, Wisconsin, USA

Consistently producing high milk quality doesn’t happen by accident. This presentation will share some of the key management practices followed by dairies that have excellent milk quality – year after year. Little management practices make a big difference.


2:40 p.m. – Processor’s Role in Milk Quality
Mark Wustenberg, Bay City, Oregon, USA

The dairy processor provides a vital link between the milk producer and the rest of the supply chain. As customers and consumers demand more supply chain transparency, both processors and producers will need to be more effective at communicating where their milk comes from and how it’s produced. Milk Quality not only forms an objective foundation for effectively communicating the condition of milk and its potential impact on product quality but also is a basic measure that speaks to overall animal health and management level. Processor support is a vital link that can and should be providing effective support to producers where needed.

General Session 3:

The Five-Point Mastitis Control Plan – Focusing on the Points
Moderator: Paul Virkler, Quality Milk Production Services, Ithaca, New York, USA


10:00 a.m. – Make the Cows the Consultants with ‘Good’ Clinical Mastitis Recording and Analysis John Wenz, Washington State University, Pullman, Washington, USA

“Good” clinical mastitis records allow us to tap into the collective expertise of cows to assess outcomes of udder health management on the dairy. What are “good” records? Are clinical mastitis episodes prevention or treatment failures? Are treatment protocols effective?


10:30 a.m. – Lessons Learned About Milking Time Hygiene in Milking Robots
Don Anderson, Quality Milk Management, Sussex, New Brunswick, Canada

Milking cows with a robot offers some unique management flexibility, but the fundamental rules around milking time hygiene still apply. This presentation will include some important lessons learned by working through milk quality challenges faced by dairy producers who have adopted robotic milking over the last 10 years.


11:00 a.m. – Culling Cows with Contagious Mastitis: An Economic Perspective
Tariq Halasa, National Veterinary Institute, Technical University of Denmark, Lyngby, Denmark

Culling cows with mastitis is an important strategy to prevent and control the disease. On the other hand, culling cows can have substantial economic consequences on the dairy farm. This presentation will give the economic reasoning behind culling decisions and modeling approaches for culling cows with mastitis and the assessment of its economic consequences. In addition, the speaker will discuss the implications of different approaches and present perspectives regarding factors that should be considered when mastitis culling decisions are made.


11:30 a.m. – Machine Milking and Mastitis Risk: Looking Ahead, With the Benefit of Hindsight
John Penry, Anexa FVC, Cognosco, Morrinsville, Waikato, New Zealand

The first real scientific contributions to understanding the possible links between milking machines, milking management and mastitis were conducted in Ireland in the late 1960s and in the United Kingdom throughout the 1970s. These studies provided the foundation for developing practical, science-based mastitis control programs for most dairying nations. Our review charts some of the diversions, dead-ends and significant leaps forward since those early days, and offers some recommendations for the path ahead.

2:00 p.m. – Featured Symposium: Blanket Versus Selective Dry Cow Therapy – Who’s Ready?
Moderator: John Middleton, University of Missouri, Columbia, Missouri, USA


2:05 p.m. – Selective Dry Cow Therapy: What are the Possibilities for North America?
Daryl Nydam, Cornell University, Ithaca, New York, USA

With decreasing profit margins, dairy producers are looking for ways to reduce expenses without compromising production or cow well-being. Further, as there is increasing interest in reducing antimicrobial drug use in animal agriculture, dairy producers and veterinarians are reassessing standards of use, including blanket dry cow therapy. Recent studies have indicated that selective dry cow therapy could improve prudent antimicrobial drug use on dairy farms and be financially positive. What are possible benefits to this approach? What does a dairy farm have to do to make this work?


2:30 p.m. – Selective Dry Cow Therapy… Are We Ready for This?
Larry Fox, Washington State University, Pullman, Washington, USA

The efficacy of dry cow therapy as an intervention strategy to help control mastitis is well established, as it cures existing infections and helps prevent the establishment of new infections. Applying this mastitis prevention strategy and other mastitis control procedures have led to dramatic reductions in contagious mastitis and a vast improvement in udder health. This presentation will acknowledge that the improvement in udder health may warrant the consideration of selective dry cow therapy, but that the vast majority of herds will profit more by selecting dry cow therapy for all their cows (blanket dry cow therapy).


3:00 p.m. – Break


3:30 p.m. – Forced to Selective Dry Cow Treatment by Legislation: Blessing or Curse?
Tine van Werven, Utrecht University, Utrecht, the Netherlands

What happens if legislation forces dairy farmers and veterinarians to implement selective dry cow treatment? Is implementation on all farms the same and how are the results on the cow, herd and national level?


4:00 p.m. – Managing and Implementing Dry-off Decisions in Large, Seasonal Calving Herds
Scott McDougall, Cognosco, Anexa Animal Health, Morrinsville, Waikato, New Zealand

With seasonal calving, and hence seasonal drying-off systems used in Australia, Ireland, New Zealand and some parts of South America, many animals may need to be selected and dried off in a relatively short time period. To deal with the mechanics of selecting appropriate cows for culling, or for differential dry-off treatments (for example, intramammary antibiotics versus internal teat sealant versus both), veterinarians and dairy farmers have developed systems – first to identify subsets of animals and second to physically undertake the dry-off process. This allows, in some cases, several hundred animals to be dried off, if required, in one day.
