Effect of amino acid supplementation on the gut microbiota of weaned piglets challenged with F18 ETEC

Weaned piglets were put on supplementation of 1% and 2% concentrations of both L-glutamate and L-aspartate for 21 days and were challenged with F18 Enterotoxigenic E. coli (ETEC). Their gut microbiota structure was compared with piglets with 1% antibiotic treatment with ETEC challenge, no treatment with ETEC challenge (positive control) and piglets without ETEC challenge. Microbiota was analyzed using 16S rRNA gene amplicon sequencing
