A 60-day feeding trail was conducted to determine the effect of dietary zinc level and temperature on growth and antioxidant enzyme in Pangasianodon hypophthalmus. The six distinct treatment groups were fed with diets prepared with different zinc levels (16, 32 and 48 mg/kg respectively) in two temperature like 34˚C and ambient temperature. After 60 days experimental trial, the growth parameters like percent weight gain, FCR, PER, SGR and enzymes Superoxide Dismutase–I and Catalase were studied. In T3 group inclusion level of 48 mg/kg of zinc with 34˚C showed maximum SGR compared to other groups. |
