When we studied the effect of quercetin on perinatal sow reproduction and suckling piglets, we found that quercetin can reduce oxidative stress and inflammation in perinatal sows, improve the uniformity and weaning weight of suckling piglets, and effectively shorten the The production process and weaning estrus interval of sows; it can also improve the intestinal microecological environment by regulating the diversity and abundance of intestinal flora of sows and piglets; it can also improve the intestinal sphingolipid metabolism and amino acid metabolism of suckling piglets. 

Reproductive performance of sows in the perinatal period and improved production performance of suckling piglets. The results of the effect on weaned piglets showed that quercetin regulates the balance of intestinal flora by regulating the NF-κB signaling pathway of weaned piglets, inhibiting pro-inflammatory factors and promoting the secretion and expression of anti-inflammatory factors, promoting the proliferation of intestinal beneficial bacteria, inhibiting the The growth of harmful bacteria can reduce the diarrhea rate of piglets and relieve the weaning stress of piglets.
