Effect of dietary phytase and wheat bran on some growth performances and phosphorus absorption function of common carp (Cyprinus carpio) fry
In this study, the effect of dietary phytase and wheat bran on some growth performances and phosphorus absorption function of common carp fry for 60 days was assessed. A total number of 180 common carp fry (20±1 initial weight) was randomly distributed in six experimental groups including, control group without any additive (basal diet), T1 (basal diet+2000 IU/Kg phytase), T2 (basal diet+4000 IU/Kg phytase), T3 (basal diet+20 g/Kg wheat bran), T4 (basal diet+40 g/Kg wheat bran) and T5 (basal diet+2000 IU/Kg phytase+20 g/Kg wheat bran). The highest body weight (150.02±4.76 g), specific growth rate (0.65±0.19%), and condition factor (3.20±0.26%) was observed in T5 (p<0.05). However, the lowest FCR (2.53±0.70) was seen in T5 (p<0.05). Also, the highest phosphorus concentration in the fry bones (2.54±0.003 ppm) was recorded in T5 (p<0.05). Results showed that using of 2000 IU/Kg phytase and 20 g/Kg wheat bran in the diet can improve growth indices and phosphorus absorption rate of common carp fry.
