Optimizing feed digestibility in pigs through exogenous enzyme supplementation
Abstract
Feed enzymes are used for improving feed digestibility and animal performance worldwide, while their efficacy remains inconsistent. This seminar presents the key findings of Xianyi’s PhD research (2022–2026), which evaluated the effects of selected commercial exogenous enzymes on the digestibility of pig diets using in vitro and in vivo models. The results provide mechanistic insights into enzyme efficacy in local feed ingredients, and offer suggestions for the enzyme selection within the current pig production context in Australia.
