Consequences of Heat Stress During Late Gestation for the Dairy Cow and Her Calf
— Dr. Geoff Dahl, University of Florida. Dr. Dahl explains why it’s critical to keep cows within their temp comfort zone — not just during lactation but throughout the dry period. Heat stress has immediate health and performance impacts on the cow as well as later impacts on her calf, even on the heifer’s first lactation. He notes key findings covering a variety of heat stress abatement strategies to sustain dairy health and productivity. Presentation | Recording
Potassium Balance and Milk Fat – K Sources Matter! — Dr. Tom Jenkins, Clemson University. In his webinar last year, Dr. Jenkins focused on “DCAD Balance and Milk Fat” (see below). Now he zeroes in on potassium (K), which is key to managing the dairy ration dietary cation-anion difference (DCAD). What are the choices for K and how can that choice can help reduce milk fat depression? What K compounds are safest and most cost-effective?

Fiber and Forage Considerations: It’s all about keeping the rumen full of something digestible — Dr. Mike Van Amburgh, Cornell University. Research in Dr. Van Amburgh’s lab supports the Cornell Net Carbohydrate and Protein System, including the development of new tools to describe how neutral detergent fiber (NDF) digestion occurs in various feeds. His presentation points the way for more efficient use of forages, including ag and food co-products. Presentation | Recording
Current Soy Protein Markets with a Global Perspective — Chris Schaffer, AGP. Chris is AGP’s Senior VP for Ag Products with more than 20 years experience in international ag commodity markets, including work with the U.S. Grains Council in Washington, DC. He provides insider’s analysis, covering:
• Market fundamentals & dynamics — global & domestic
• Market outlook for 2020 & beyond
• Soy crush margin trend — what to watch for
• Price management options
Rumen Bypass Soy Protein — Dr. Dave Gast, AGP. Dr. Gast is Director of Nutrition and Technical Services for AGP. Rumen bypass soy protein is “boots on the ground” when it comes to cost-efficient dairy production and Dr. Gast has extensive research and development experience in this field. In this presentation he answers:
• What exactly is a rumen undegraded (bypass) protein product?
• How is it manufactured and why is that important?
• How do specific products perform versus other technologies, including extruded soy?
• What is the cost-benefit payback for AminoPlus®?
Macro Minerals: Impact on DCAD — Pat Kahle, D&D Ingredient Distributors. Pat, D&D’s Sales Manager and facilitator of Dairy Knowledge X-Change, earned his BS in Animal Science at The Ohio State University. Pat’s career spans decades in the fields of dairy nutrition and health and D&D customers and their advisors rely on his extensive knowledge of dairy feed ingredients. Presentation
Inflammation, Immunity and Transition Management — Dr. Barry Bradford, Michigan State University. Dr. Bradford earned his BS in Animal Science and Biochemistry at Iowa State University, then his PhD in Animal Nutrition from Michigan State University. After 13 years in research and teaching at Kansas State University, he recently returned to Michigan State in the Clint Meadows Endowed Chair in Dairy Management. With expertise in dairy metabolic physiology, he has studied how nutrients impact the cow’s immune status. Presentation
Profitability: Fat, Protein or Volume? — Dr. Benjamin Wenner, The Ohio State University. Dr. Wenner earned his BS in Animal Science specialized in agribusiness management at Michigan State University, then his MS and PhD at The Ohio State University where his doctoral research focused on dairy rumen simulation in the lab. Following R&D and tech service support for Perdue Agribusiness, he has returned to Ohio State as an assistant professor, helping to improve the use of dairy research data and support producer decision making. Presentation
DCAD Balance and Milk Fat — Dr. Tom Jenkins, Clemson University. Emeritus Professor Jenkins received his BS in Animal Science and MS in Animal Nutrition from Pennsylvania State University and his PhD in Nutritional Biochemistry from Cornell University. At Clemson, he has focused on lipid metabolism by the rumen microbial population and managing the dairy ration dietary cation-anion difference (DCAD) for optimal dairy performance. Presentation
