Fig. 3From: Alginate oligosaccharide-induced intestinal morphology, barrier function and epithelium apoptosis modifications have beneficial effects on the growth performance of weaned pigsEffects of alginate oligosaccharide on the sIgA content in the duodenum (a), jejunum (b) and ileum (c) of weaned pigs (immunohistochemistry; × 400). Values are means (8 pigs/treatment), with standard errors represented by vertical bars. *P < 0.05 (indicates that the sIgA content is significantly higher in the AOS group than CON group). CON, control (a corn-soybean basal diet); AOS, alginate oligosaccharide (the basal diet supplemented with 100 mg/kg alginate oligosaccharide). sIgA, secretory immunoglobulin A. Scale bar is 40 μmBack to article page
