History of Feeding Fat to Dairy Cattle

Guests:Dr. Tom Jenkins, Clemson UniversityDr. Don Palmquist, The Ohio State UniversityDr. Kevin Harvatine, Pennsylvania State UniversityWe 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. 9:20Dr. Jenkins discussed the early failures and how they came to trial making calcium salts and seeing some early success in their research. 19:26To 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. 29:36The trio gave their input on the practical limits of fat inclusion. 39:51With growing herd averages for pounds of milk produced, the experts discussed how to get enough into the diets to meet the growing output. 47:21Dr. Harvatine discussed his outlook on the future of how fatty acids can modify physiology. 55:48If you want one of our new Real Science Exchange t-shirts, make sure to screenshot your rating, review or subscription, and email a picture to anh.marketing@balchem.com. Include your size and mailing address and we’ll get a shirt in the mail to you.Please subscribe and share with your dairy industry friends to bring more friends to join us around the Real Science Exchange virtual pub table.This podcast is sponsored by Balchem Animal Nutrition and Health.
