【 摘 要 】

The purpose of this study was to determine the effect of adding phytase enzyme in the feed on digestibility of feed, efficiency of feed utilization, relative growth rate and survival rate of Common carp (Cyprinus carpio). Fish samples in this research were Common carp with an average - weight of 3.34 ± 0,16 g/fish. The treatments were adding the phytase enzyme in the feed with the different level of doses. Those were A (0 U kg-1feed), B (500 U kg-1feed), C (1.000 U kg-1feed g) and D (1.500 U kg-1feed). Observation was conducted on digestibility of protein (ADCP), digestibility of phosphor (ADCF), efficiency of feed utilization (EFU), relative growth rate (RGR), protein efficiency ratio (PER), feed conversion ratio (FCR), survival rate (SR) and water quality parameters. The results show that the addition of phytase enzyme significantly (PP, ADCF, EFU, RGR, FCR, and PER, on the other hand it insignificantly (P>0.05) affected on SR of common carp. Based on results, it was concluded that optimum doses of phytase enzyme feed in terms of digestibility of feed, efficiency utilization of Feed and growth rate of Common carp ranges from 943 to 1100 U kg-1feed.
