Dr. Amy Petry: Fiber in Swine Feed | Ep. 234
Traditionally considered an antinutrient because it dilutes energy and other nutrients' digestibility, fiber has gained more recognition in recent years. More specifically, fiber is used strategically to elicit more calories from our feedstuffs and to use fibrous products more sustainably. Pigs' gut health and functions are also improved by adding both insoluble and soluble fibers to their diet. So, in this episode, Dr. Amy Petry explores the biases and misconceptions and unravels fiber's true capabilities as an essential part of a pig's diet. She also discusses the different types of fiber, their physiological impacts on swine, and the many benefits that both insoluble and soluble fibers bring to the table.
"We've talked a lot about the many beneficial aspects of fiber. But we have to keep in mind that there are anti-nutritive effects that are associated with it.”
