Abstract – This study was designed to evaluate the body weight composition of Nile tilapia, (Oreochromis niloticus) fed diets with various inclusion levels of Phyprozyme HP. Phyprozyme HP enzymes are standardized to contain a combination of Protease, Xylanase, Hemicellulase, and Phytase. The body weight composition was presented as a percentage of moisture, fat, ash, and crude protein. The fish samples in this study used Nile tilapia with an average weight of (11.8 ± 8.6) g/fish and the stocking density of 20 fish/ hapa (70×45×90 cm3). Eight treatments with two replicates were used: T1 control (0,0), T2 (0,05), T3 (0,12), T4 (0,19), T5(0,26), T6 (0,33), T7 (0,40), and T8 (0,47) g phyprozyme HP/ kg-1 feed and were fed three times daily (7:00 AM, 12:00, and 16:00 PM) at feeding rate of 5 % of the total body weight. After 56 days, there were no significant differences between the treatments in terms of moisture and protein contents of body composition.The highest value (81.52 ± 2.96) of moisture was observed with fish fed (T8) and the lowest value (77.65 ± 3.32) was obtained with fish fed (control). The highest value of protein (11.68 ± 0.72) was observed with (initial weight) and the lowest value (7.43 ± 0.12) was obtained with fish fed (control). There was a significant difference (P<0.05) in crude fat and ash contents between initial weight and other dietary treatments. Crude fat content was highest in initial weight (2.45 ± 0.49) and lowest in fish fed (T2) (0.39 ± 0.02). The ash content was highest in T7 (2.67 ± 0.28) and lowest in fish fed (T6) (1.47 ± 0.06).

I. INTRODUCTION
Nile tilapia, (Oreochromis niloticus) is an extensively cultured fish because it grows and multiplies under a variety of environmental conditions and tolerates handling stress. Tilapias do well in extensive, semi-intensive and intensive culture systems[1]. Nile tilapia has become the predominant culture species due to its proven superior growth compared to the other species [2]. Tilapias are now the second most commonly farmed fish next to carps [3]. Currently, tilapias are cultured in about 100 countries in tropical and subtropical regions.
