Effects of dietary fibers with different physicochemical properties on the constipation of sows and the health of piglets

Constipation in sows during late pregnancy increases farrowing duration and thereby increases the number of stillborn piglets. Dietary fiber supplementation can change intestinal microbiota composition, thereby increasing intestinal motility and reducing constipation in many animal models. However, the effects and mechanisms of fibers with different physicochemical properties on constipation have not been fully explored. The aim of this study is to find the best source of fiber for late gestation and lactating sows from a sow and piglet health perspective.
