Bacillus subtilis fmbj ameliorates lipopolysaccharide-induced intestinal dysfunction in broilers by enhancing the SIRT1/PGC1α pathway.

ABSTRACT: This study aimed to explore the impact of dietary Bacillus subtilis fmbj (BS) supplementation on acute intestinal dysfunction induced by lipopolysaccharide (LPS) in broilers. One hundred and eighty 1-day-old male Arbor Acres broilers were randomly divided into three treatment groups, each comprising ten replicates of 6 birds. On d 20, LPS-challenged (LPS group and LPS-BS group) and LPS-unchallenged (CON group) broilers received intraperitoneal injections of 1 mg/kg body weight LPS solution and an equivalent volume of sterile saline, respectively. Compared to the CON group, LPS disrupted (P < 0.05) the morphology of the small intestine (jejunum or ileum), exacerbated (P < 0.05) serum, small intestinal, and small intestinal mitochondrial antioxidant capacity, induced (P < 0.05) small intesti
