Effects of synbiotic mixture of lactulose and Bacillus coagulans on histological changes and morphology of jejunum and ileum in piglets challenged with lipopolysaccharide. Representative haematoxylin & eosin (H&E) staining images were obtained at 200 × magnification with black bar = 50 μm. A1–4 Jejunum tissue images; B1–4 Ileum tissue images; C1–3 Jejunum morphology; D1–3 Ileum morphology. CON_-saline (negative control), basal diet; LPS_-LPS (positive control), basal diet; CTC_-LPS, basal diet + CTC (75 mg/kg); and SYN_-LPS, basal diet + synbiotic mixture of lactulose and Bacillus coagulans
