Schematic of the findings. L. johnsonii drove the normalization of the butyric acid transformation pathway, leading to homeostasis ( L. johnsonii administration). In the dietary copper-rich piglet model (Copper-rich), high-copper-induced extinction of L. johnsonii and abnormal metabolism of acetate and butyrate, leading to epithelial barrier dysfunction.
