Abstract An-eight week experiment was conducted to test efficacy of corncob derived xylooligosaccharides (CDXOS) on mucosal and serum immune, disease resistance, and growth performance of Nile tilapia ( Oreochromis niloticus ). Three hundred and twenty tilapia fingerlings (20.72 ± 0.02 g) were fed the following diets; 0 (Diet 1- control), added 5 – (Diet 2), 10 – (Diet 3), and 20 g kg −1 CDXOS (Diet 4). After 4 and 8 weeks feeding were mucosal, serum immune responses, and growth performance measured. A challenge test (15 days) against Streptococcus agalactiae was conducted after 8 weeks post-feeding. A significant ( P P −1 CDXOS vs. the other treatments. With regard to the challenge test, relative percent survival (RSP) of Nile tilapia fingerlings fed Diet 2, Diet 3, and Diet 4 was 34.78%, 60.87%, and 30.43%, respectively. Among the supplemented groups, dietary inclusion of 10 g kg −1 CDXOS revealed significant ( P S. agalactiae than the other groups. Regarding growth performance, final weight, weight gain, specific growth rate, and feed conversion ratio were remarkably ( P −1 CDXOS treatment. In conclusion, inclusion of 10 g kg −1 CDXOS derived from corncob improved growth performance and health status of Nile tilapia fingerlings.
