The effects of different types of non-starch polysaccharides (NSPs) on growth performance, antioxidant activity and intestinal mucosal barrier function of tilapia (Oreochromis niloticus) were evaluated through a 10-week feeding trial. Eleven isonitrogenous (32% crude protein) and isoenergetic (20 MJ/kg) diets were prepared without (control) or with 3.96% arabinoxylan, 0.92% β-glucan, 1.06% mannan, 7.92% pectin, 6.60% cellulose, 1.06% lignin, 1.51% alduronic acid, 13.86% soluble NSPs (sNSP, 3.96% arabinoxylan + 0.92% β-glucan + 1.06% mannan + 7.92% pectin), 9.17% insoluble NSPs (iNSP, 6.60% cellulose + 1.06% lignin + 1.51% alduronic acid) and 23.03% NSP (13.86% sNSP + 9.17% iNSP), respectively. Dietary inclusion of β-glucan or pectin significantly increased weight gain rate (WGR), daily growth coefficient (DGC), hepatic lactase and plasma catalase (CAT) activities. Dietary inclusion of arabinoxylan or mannan significantly decreased hepatic lactase activity,WGR and DGC, significantly increased diamine oxidase (DAO) activity. Dietary inclusion of iNSP or NSP significantly increased WGR, DGC, feed intake, feeding rate, intestinal lipase and lactase activities, hepatic amylase and lactase activities, plasma superoxide dismutase (SOD) and CAT activities, and hepatic SOD activity, significantly reduced pepsin activity and hepatic malondialdehyde (MDA) content. Furthermore, dietary inclusion of sNSP significantly increased feed coefficient ratio, feed intake, pepsin and hepatic trypsin activities, hepatic MDA and plasma DAO contents, and significantly decreased protein efficiency, plasma CAT and hepatic peroxidase activity. These results showed that dietary inclusion of arabinoxylan, mannan or sNSP negatively affected the growth and health of tilapia, while dietary inclusion of β-glucan, pectin or iNSP shown a positive effect; dietary inclusion of iNSP can ameliorate the negative effects produced by sNSP.
