Ornithine α-Ketoglutarate Alleviates Inflammation via Regulating Ileal Mucosa Microbiota and Metabolites in Enterotoxigenic Escherichia coli-Infected Pigs.

ABSTRACT: Enterotoxigenic Escherichia coli (ETEC) is one of the main causes of diarrhea in weaned piglets, and ornithine α-ketoglutarate (OKG) as a food supplement has been shown to improve intestinal immune status in animals and humans. However, it remains unknown whether OKG alleviates inflammation through the regulation of gut microbiota and its metabolites on ETEC-infected piglets. This study was conducted to explore the impact of OKG on growth performance, immunity, and ileal mucosa microbiota and its metabolites in piglets infected with ETEC. On a total of 40 pigs, a 2 × 2 factor design was performed; the major factors were diet (basal diet or 1% OKG diet) and challenge (E. coli or LB Broth). The results showed that ETEC-infection inhibited growth performance, and OKG supplementa
