Fig. 4From: Alginate oligosaccharide-induced intestinal morphology, barrier function and epithelium apoptosis modifications have beneficial effects on the growth performance of weaned pigsPercentage of apoptotic cells in the small intestine of weaned pigs fed diets containing or lacking alginate oligosaccharide. Frames were divided into four quadrants: Q2–1 represents necrotic cells; Q2–2 represents late-stage apoptotic cells; Q2–3 represents normal cells; Q2–4 represents early-stage apoptotic cells. CON, control (a corn-soybean basal diet); AOS, alginate oligosaccharide (the basal diet supplemented with 100 mg/kg alginate oligosaccharide). 7-AAD, 7-aminoactinomycin DBack to article page
