The present study was aimed to evaluate the efficiency of betaine and 0.2% β-glucan on growth performance and survival rate of common carp. 120 fingerlings of Cyprinus carpio weight ranged between 46-46.5g were randomly distributed into six treatment groups. Fish were fed different betaine concentration: 0.15% (T1), 0.2% (T2), 0.25% (T3) and 0.3% (T4). The fifth group (T5) was fed 0.2% β-glucan, control group was fed 0% of betaine and β-glucan in the diet. All treatments fed twice a day at rate 3% B.W for 56 days. The study was conducted at College of Veterinary Medicine/ University of Baghdad, Ichthyology laboratory, Baghdad, Iraq, from 27/4/ to 21/6/2016.
Results of feeding trail in treated groups with betaine supplementation showed significant increase (P< 0.05) in all growth parameters (i.e:final weight, DWG, RGR, SGR(%), FCR, FCE) compared with the control group, and the highest values were recorded in T4 supplemented with betaine 0.3%. Also, survival rate recorded highest value (100%) in treatment groups supplemented with betaine 0.3% andβ-glucan 0.2% in comparison with control group (80%), suggesting that the high level of betaine (0.3%) improve growth rate and survival rate in common carp
