Dietary konjac flour (KF) supplementation could improve insulin sensitivity and reproductive performance of sows, but its high price limits its application in actual production. This study investigated the impact of 2% konjac flour (KF) and 2% combined dietary fiber (CDF, containing 15% KF, 60% bamboo shoots fiber, and 25% alginate fiber) supplementation from the last 50 days of gestation to farrowing on farrowing performance, placental function, insulin sensitivity, and gut microbiota of gilts. Results indicated that KF or CDF supplementation during this time could improve the farrowing performance of gilts possibly by improving insulin sensitivity and gut microbiota, and increasing placental vascular density. Meanwhile, CDF could lower the production cost per live-born piglet and have a similar effect to KF, thus a cheaper alternative to KF in actual production. This study facilitates understanding the beneficial effects of KF and non-conventional dietary fiber sources on the reproductive performance of gilts.
