AbstractThe effects of prebiotic-fructooligosaccharide (FOS) on growth performances, lysozyme and phagocytosis activities of Climbing perch (Anabas testudineus Bloch, 1792) were determined. The factorial completely randomized experiment (2 × 3) was applied. Three experimental diets were formulated to contain 0, 1, and 2% FOS in pellet diets with two feeding levels including either 3% of body weight or satiation. Fish (mean body weight of 9.33±0.06 g) had been raised for 120 days. The results showed fish fed 2% FOS supplementary diet at 3% of body weight and 0, 1, 2% FOS diets at satiation gained greater body weight, specific growth rate, and increased weight than perch received a feed without FOS at 3% of body weight (P<0.05). Moreover, climbing perch obtained feeds with 1 and 2% FOS at 3% of body weight and satiation had better daily feed intake and total feed intake (P<0.05). Furthermore, fish received diets with 1 and 2% FOS at 3% of body weight and satiation had significantly higher (P <0.05) lysozyme activity and percent phagocytosis than fish fed without FOS diet both two feeding levels. In sum, the 1% prebiotic-FOS supplemented diet with satiation feeding can improve growth performances and enhance non-specific immune responses of Climbing perch, also influence the total production and feed cost.
