Abstract:
Glycerol-lactate esters are energy supplements for exercise, but effects of trilactic glyceride (TLG) on intestinal function and hepatic metabolism are unknown. We found that dietary supplementation with 0.5% TLG to weanling piglets decreased plasma concentrations of low-density lipoprotein and gamma-glutamyl transferase but increased those of D-xylose and high-density lipoprotein. TLG supplementation enhanced mRNA levels for fatty acid synthase (FASN) and SLC27A2 in white adipose tissue; insulin receptor in duodenum; aquaporin-8 in ileum, jejunum and colon; aquaporin-10 in duodenum and ileum; nuclear factor like-2 in jejunum and colon; glutathione S-transferase and phosphoenolpyruvate carboxykinase-1 in intestines; and abundances of claudin-1 and occludin proteins. TLG supplementation decreased mRNA levels for: hepatic hormone-sensitive lipase E, lipoprotein lipase, FASN, insulin-like growth factor-binding protein-3, and SLC27A2; and intestinal lipoprotein lipase, FASN and NADPH oxidase. Furthermore, TLG supplementation enhanced abundances of genus Bifidobacterium, while reducing abundances of family Enterobacteriaceae in ileum, colon and cecum; jejunal caspase-3 protein and diarrhea rate. In conclusion, dietary supplementation with TLG modulated lipid metabolism and alleviated diarrhea by improving intestinal function and regulating intestinal microflora in piglets.
