The use of plant protein in the artificial feed needs to be reckoned since plant protein contains phytate acid. To solve the problem is by adding phytase enzyme. This study aims to identify effect of phytase enzyme in the artificial feed and determine optimal dose of phytase enzyme on feed digestibility, nutrient efficiency utilization, and growth of giant tiger prawn (Penaeus monodon). The shrimp used in the study was giant tiger prawn (P. monodon) with the average weight of (1.19 perpendicular to 0.06) g per shrimp and the density of one shrimp per L. Methodology used in this study was experimental treatments with complete random design. The study consisted of four treatments and three repetitions. The treatments were by adding phytase enzyme in the different doses, namely: A (0 FTU . kg(-1) diet), B (500 FTU . kg(-1) diet), C (1 000 FTU . kg(-1) diet) and D (1 500 FTU . kg(-1) diet). Data collected were from variables of digestibility raw protein (DRP), digestibility total protein (DTP), nutrient efficiency utilization (NEU), relative growth rate (RGR), survival rate (SR) of giant tiger prawn (P. monodon) and water quality. The results show that the treatments significantly (p < 0.01) affected on the DRP, DTP, NEU, and RGR; however, they did not significantly (p > 0.05) influence on the survival rate. The optimum dose of phytase enzym for feed digestibility, feed utilization and the growth of giant tiger prawn (P. monodon) was 1 000 FTU . kg(-1) feed. The water quality was still in the viable range for giant tiger prawn cultivation. (C) 2016 The Authors. Published by Elsevier B.V.
