【 摘 要 】

Papain is an enzyme capable of hydrolyzing protease into a more simple elements i.e. the peptide to amino acids. The enzyme in the feed can increase the absorption of protein and digestion rate in the digestive tract of fish. This research examined the effective level of enzyme papain to increase the Feed Utilization Efficiency (FUE), Protein Efficiency Ratio (PER) and Average Daily Gain (ADG). This research used Completely Randomized Design (CRD) with five treatments i.e. treatment A (control), treatment B (1.5 %), treatment C (2.25 %), treatment D (3 %) and treatment E (3.75 %) in triplicate. Tilapia (Oreochromis niloticus) with the average initial weight of 17 g, and initial total lenght of 8-10 cm was fed three times daily at feeding rate of 5 % of the total body weight. The results showed that supplementation of papain in the feed significantly increased the activity of protease, FUE, PER and ADG. The optimal dose of the enzyme papain at 3.75 % was able to increase 48.31 % of FUE, 2.13 % of PER and 2.07 % of ADG.
