Dr. Amy Petry: Fiber And Enzymes | Ep. 218

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Amy Petry from the University of Missouri discusses how dietary fiber and enzyme technologies influence energy utilization in swine diets. She explains the complexity of fiber, the role of xylanase in reducing digesta viscosity and improving nutrient accessibility, and why production context matters across growth and sow systems. Dr. Petry also covers practical considerations for balancing feed efficiency, diet cost, and performance expectations. Listen now on all major platforms. "Enzyme objectives must be defined clearly, whether targeting digestibility, feed efficiency, or energy utilization." Meet the guest: Dr. Amy Petry https://www.linkedin.com/in/amy-petry-b1508a1a4/ is an Assistant Professor at the University of Missouri with training in physiology, biochemistry, statistics, and swine nutrition. She earned her Ph.D. from Iowa State University. Her research focuses on improving fiber utilization, understanding diet and physiology interactions, and optimizing energy and nutrient supply in swine systems. Liked this one?
