Abstract

L-threonine (Thr) facilitates gut barrier restoration, yet its coordinated link with gut microbiota and intestinal barrier-related genes remains unclear. This study assessed the effects of drinking-water Thr supplementation (0, 150, 300, 600 mg/kg BW) on growth performance, jejunal morphology, cecal microbiota and…
