| Abstract | This study aims to investigate the effects of papain supplemented diet on the growth performance and feed utilisation of common lowland frogs, as well as the water quality of the frog culture system. A diet with 35% protein and 3,000 Kcal/Kg-1 and supplemented with papain extract was fed to the frogs for 90 days. The supplementation of the enzyme extract at 2% enhanced growth performance and feed utilisation of the frogs (P<0.05) without affecting the survival rate (P>0.05). Also, papain supplementation at 2% can reduce ammonia and nitrite levels in the frog culture system. Thus, water quality parameters, pH and temperature were within a standard range |
