Abstract:
This study was carried out to determine the effects of betaine on the growth performance and carcass synthesis of Caspian Roach (Rutilus rutilus caspicus) fingerlings. Fish with mean weight about 1.91±0.01g after adaptation were divided to 2 treatment groups (0.5 and 1% of diet) and control (0%). After 8 weeks feeding with betaine added diet, data was analyzed by excel 2010 and Spss 18.Added betaine had anincreasing effect on final weight, weight gain (BWI), and a decreasing effect on FCR, but not significantly. Food intake increased significantly as added betaine increased (p<0.05). Betaine is known as a flavor attractant and improves growth factors of Caspian Roach (Rutilus rutilus caspicus) fingerlings
