Effects of Hydrolysable Tannins as Zinc Oxide Substitutes on Antioxidant Status Immune Function Intestinal Morphology and Digestive Enzyme Activities in Weaned Piglets

摘要

Zinc oxide (ZnO) is generally used to control diarrhea and improve gut health in weaned piglets. To protect weaned pigs from intestinal injuries and to decrease environmental zinc load, it is essential to find an alternative to ZnO. In the present study, hydrolysable tannins (HT) showed decreased diarrhea rate and improving gut health via multiple pathways. Herein we demonstrate that HT supplementation may be a potential alternative of ZnO in weaned piglets.
