Mannan oligosaccharides improved growth performance and antioxidant capacity in the intestine of on-growing grass carp (Ctenopharyngodon idella)

This study evaluates the effects of dietary mannan oligosaccharides (MOS) supplementation on growth performance and antioxidant capacity, as well as investigates its related signalling molecule mechanism in the intestine of on-growing grass carp (Ctenopharyngodon idella). A total of 540 on-growing grass carp (215.85 ± 0.30 g) were fed six diets containing graded levels of MOS supplementation (0, 200, 400, 600, 800 and 1000 mg kg−1) for 60 days....
