Feed additive of curcuma flour (Curcuma xanthorhiza) in commercial feed to growth rate and feed efficiency of tambaqui (Colossoma macropomum)

Abstract

Tambaqui (Colossoma macropomum) is much demand by the public as a consumption fish. Addition of curcuma in feed to increase fish appetite because it contains curcumin and essential oil. The purpose of this study was to determine the growth rate and food efficiency in tambaqui (Colossoma macropomun) with feed additives of curcuma flour (Curcumaxanthorhiza) on commercial feed. The research method used is the experimental method. The research design used was a Completely Randomized Design (CRD). Having 5 types of treatment with repeated 4 times. The treatment used was the addition of curcuma flour on commercial feed, namely P1 (2.5%), P2 (5%), P3 (7.5%), P4 (10%) and P0 (100% commercial feed). The main parameters observed were the growth rate and feed efficiency. The supporting parameters observed were water quality (temperature, pH, DO and ammonia). Data analysis using Analyze of Variance. The results of the feed additive of curcuma in commercial feed of tambaqui have the highest average value of growth rate in P0 treatment, but not significantly different (P> 0.05) with treatment P1, P2, P3 and P4. Feed efficiency values have the highest average value in P2 treatment, but not significantly different (P> 0.05) with treatments P0, P1, P3 and P4.
