History of Feeding Fat to Dairy Cattle

Guests:
Dr. Tom Jenkins, Clemson University
Dr. Don Palmquist, The Ohio State University
Dr. Kevin Harvatine, Pennsylvania State University

We gather around the Real Science Exchange virtual table for another pubcast with leading researchers to dive into this week’s topic of the history of feeding fat to dairy cattle. Scott Sorrell and Dr. Clay Zimmerman are joined by tonight’s guests who span the history of the topic with Dr. Don Palmquist being one of the founding fathers and Dr. Tom Jenkins also providing much of the depth as we dive in on this topic. Dr. Kevin Harvatine is not new to the Real Science Exchange and we are excited to have him back for this discussion.

Dr. Palmquist and Jenkins discussed the early years of their research finding the right combination, source and ration approach to including fat into dairy cow diets. 9:20

Dr. Jenkins discussed the early failures and how they came to trial making calcium salts and seeing some early success in their research. 19:26

To give perspective on today’s approach, Dr. Harvatine shared he’s seeing a reasonable amount of progress the last couple of years to getting fatty acids rather than extract or crude fat into rations. 29:36

The trio gave their input on the practical limits of fat inclusion. 39:51

With growing herd averages for pounds of milk produced, the experts discussed how to get enough into the diets to meet the growing output. 47:21

Dr. Harvatine discussed his outlook on the future of how fatty acids can modify physiology. 55:48
