General Session 1: Hot Topics

10:15 a.m.

 

A Beginner’s Guide to the Milk Microbiome
Pamela Ruegg, Michigan State University, East Lansing, Michigan, USA

The microbiome is a hot topic and is the subject of tremendous research interest. However, many of the concepts of bovine milk microbiome research are unfamiliar and interpretation of research results is often confusing. In this presentation, terminology and methods of how the bovine milk microbiome is determined will be described. Research about the bovine milk microbiome will be presented, stressing research related to udder health and milk quality. Limitations to existing research will be explained and directions for future advances will be considered.

 

11:00 a.m.

Enteric Outbreaks Linked to Raw Milk
Megin Nichols, Centers for Disease Control and Prevention, Atlanta, Georgia, USA

The Centers for Disease Control and Prevention (CDC), along with federal and state partners, investigate illness outbreaks linked to consuming raw dairy products. Raw milk-associated illness outbreaks occur frequently. Raw milk is an ideal vehicle for many pathogens, because it can easily be contaminated and provides a hospitable environment for many pathogens to survive and grow. Implementation of pasteurization greatly reduces illness risk and has been celebrated as one of the public health triumphs of the hygienic revolution. However, interest in drinking raw milk has been increasing in recent years. Advocates cite an array of alleged health benefits of unpasteurized milk, especially for allergic and atopic conditions, while public health authorities dismiss these claims as lacking scientific validity. Conversely, these advocates often downplay the infectious risks of unpasteurized milk, citing improved hygienic practices on dairies and microbiologic testing of unpasteurized milk as greatly reducing its risks, whereas public health authorities note the continued and even increased occurrence of outbreaks associated with unpasteurized milk. During this presentation, we will review illness outbreaks linked to raw milk and discuss the scientific basis for the CDC recommendation to drink pasteurized milk.

 

11:30 a.m.

From Cows to People and Back Again: Antimicrobial Resistance Risks
Dale Moore, Washington State University, Pullman, Washington, USA

For several decades, the use of antimicrobials in food animal production has been touted as a major risk for the development of antimicrobial resistance in human pathogens. This presentation will share some of the recent risk assessments for that claim and highlight current antimicrobial uses in cattle and areas for improvement of antimicrobial stewardship in the dairy industry.

General Session 2: Udder Health in Heifers: A Fresh New Look

2:00 p.m.

Heifer Mastitis – What About It?
Paula Ospina, Quality Milk Production Services at Cornell University, Ithaca, New York, USA

It is time to review heifer mastitis literature; it has been at least five years since the last comprehensive review was completed. A current review, along with applied statistical methods to identify risk factors and possible prevention and control strategies, will help producers and veterinarians develop strategies to reduce risk. We also have recent data from three farms in New York State, which have been monitoring fresh cow infections for more than one year, the prevalence of pathogens causing infections in heifers versus cows, along with changes in milk production based on these pathogens.

 

2:30 p.m.

Mastitis in Dairy Heifers: The Damage We Cannot See
Benjamin Enger, The Ohio State University, Columbus, Ohio, USA

Dairy replacement heifers are essential to a dairy herd’s future. Unfortunately, intramammary infections are common and often overlooked in these animals. This talk will review the prevalence and causative agents affecting dairy heifers and take an in-depth look into how these infections impact the mammary gland during this critical period of mammary growth and development.

 

3:00 p.m.

The Impact of Interventions During Late Gestation in the Postpartum Udder Health of First-calf Heifers
Vinnie Machado, Texas Tech University, Lubbock, Texas, USA

Clinical and subclinical mastitis in first-calf heifers represent a significant challenge to dairy producers. Heifer mastitis is a multifactorial disease; and in early lactation, its incidence is higher than in multiparous cows. This presentation will summarize how several prepartum interventions can mitigate mastitis in primiparous cows. Special focus will be given to the impact of prepartum infusion of intramammary antimicrobials and internal teat sealant on udder health of first-calf heifers.

 

3:30 p.m. – Break

 

4:00 p.m.

Genetic Selection for Udder Health
Dan Weigel, Zoetis, Kalamazoo, Michigan

Producers in the United States have benefitted from genetic selection for improved udder health since somatic cell score evaluations were introduced in 1994. More recently, genetic evaluations for the trait mastitis in U.S. Holsteins have become available. This presentation will look at research results on how useful mastitis genetic predictions are for dairy producers.

 

4:30 p.m.

Horn Flies! Why They Love Cattle and Why Controlling Them May Reduce the Incidence of Mastitis
R.T. Trout Fryxell, University of Tennessee, Knoxville, Tennessee, USA

Several fly species are found on dairy cattle, but the horn fly is an obligate ectoparasite that takes a blood meal about 30 times a day and has been incriminated as a vector of Staphylococcus aureus. This presentation will discuss horn fly identification, why we need to control this pest, current control methods and new research to help manage these flies.

General Session 3: Milk Quality Matters

10:00 a.m.

Why Milk Quality Matters
Nicole Martin, Cornell University, Ithaca, New York, USA

The quality of processed dairy products depends on best practices from grass to glass. Bacterial contaminants may enter the dairy product chain at the farm level or in the processing facility, and both play a major role in product quality. Addressing these different types of bacterial contamination requires a comprehensive and cooperative approach by producers and processors.

 

10:30 a.m.

Milk Quality Still Pays
Brandon Treichler, Select Milk Producers, Canyon, Texas, USA

With today’s historically low milk prices and eroding milk quality premiums, it’s easy to assume that the quality of milk no longer matters. But don’t be fooled! Now, as much as ever, producing high quality milk puts more money in the bank. We will discuss the relationship between milk quality and net farm income, as well as how milk quality impacts consumer perceptions of dairy products.

 

11:00 a.m.

Southeast Quality Milk Initiative
Gina Pighetti, University of Tennessee, Knoxville, Tennessee, USA

Many commonalities exist regarding effective mastitis control programs. However, each region of the United States faces unique challenges. The Southeast Quality Milk Initiative (SQMI) was formed by milk quality professionals from six land grant universities to identify those unique and common factors critical for mastitis control programs in the Southeast. The initial presentation will summarize key findings regarding social factors relative to practice adoption and milk quality, farm practices that influenced high quality milk, and tools and resources generated through this initiative. SQMI also provided boots-on-the-ground work with producers to meet their milk quality goals.

 

11:40 a.m.

Featured Symposium: Consumers and Communication

2:00 p.m.

Saturated Fat and Cardiovascular Disease: What is the evidence?
Andrew Samis, Queen’s University, Kingston, Ontario, Canada

In today’s world, one can find many studies, guidelines and press articles that espouse the benefits of reducing the consumption of saturated fat as a means of reducing cardiovascular disease. One can, however, also find many studies, guidelines and press articles advocating that saturated fat is unrelated to heart attack and stroke and, in some cases, even beneficial in preventing these diseases. It comes as no surprise, then, that these opposing and strongly expressed viewpoints create confusion.

This presentation will take a step-by-step historical approach to review how the concept of reducing dietary fat became worldwide public policy. Specifically, we’ll trace how the concept evolved from the early 1900s to today. With an evidenced-based approach, the consumption of dietary fat and its relationship to cardiovascular disease will be reviewed. The results might surprise you!

 

2:45 p.m.

A Closer Look at the Evidence: A Dietitian’s Case for Dairy
Erin Green, Central District Health Department, Boise, Idaho, USA

There is good reason why dairy continues to be in a food group of its own in mainstream nutrition messaging. The unique nutrient package offered in traditional dairy products plays a vital role in human development, disease prevention and even sports performance. This session will present current evidence for dairy’s health benefits, as well as dispel some of the common misconceptions about one of nature’s best nutrition sources.

4:15 p.m.

New Discoveries in Human Health that May Lead to New Markets for Dairy Producers, Processors and Retailers
Jim Cullor, University of California, Davis, Davis, California, USA
Value-added products with their origins in fluid milk have provided the dairy industry with new and exciting markets in recent decades. With new discoveries in human and animal health, even greater markets will be presenting themselves to our industry. New categories in “designer milks” expanded opportunities in feeding consumer and scientific demands for “precision diets” in which milk and its components will play a tremendous role. Energy drinks continue to grow in popularity and milk components can play an even larger role in providing enhanced versions in many of these categories. The intestinal microbiome’s role in human and animal health is highly dependent upon milk and its constituents. These new scientific discoveries demand more attention from our industry in order to address future consumer markets. Exciting times are ahead if we work together in addressing these new opportunities.
