Abstract

Effect of dietary mannan oligosaccharide (MOS; activeMOS® ) on growth, survival, body composition and some hematological parameters in carp juvenile (Cyprinus carpio) were investigated for 45 days. Basal diet were supplemented with 0 (control), 1.0, 2.0 and 3.0g kg-1 MOS in a totally randomized design trial in triplicate groups. The experiment carried out in 100 liters PVC tanks. 20 juvenile carp with initially average weight 1.3±0.17g were stocked in tanks and fed up. There were no significant differences in growth and feeding parameters between fish fed control and MOS supplementation diets (P>0.05).The highest and the lowest growth performance were observed in 1.0g kg-1 MOS and control treatment, respectively. There were no significant differences in survival rate among experimental groups (P>0.05). No significance difference was observed in body composition, but in group fed with 1.0g kg-1 MOS showed higher protein carcass (P>0.05) than other group. An elevation of haematocrit, lymphocyte (p<0.05), WBC, RBC, Hb, eosinophil and neutrophil (P>0.05) were found in the fish fed by 1.0g kg-1 MOS. The result indicated that 1.0g kg-1 MOS can improved growth performance, survival, final production and some blood parameters of carp juvenile and it is appropriate for supplementation in the diet of cultured juvenile carp.
