Effects of organic selenium supplemented diet on growth performance and antioxidant response in Cirrhinus mrigala
AQUACULTURE RESEARCH(2020)
Abstract
The present study was conducted to evaluate the horizontal ellipsis effect of dietary selenium on growth performance and antioxidant enzymes activity in Cirrhinus mrigala for a period of 45 days. Four numbers of experimental diets were prepared, T-c for Control (0 mg organic selenium/kg of diet), T-1 (2.5 mg organic selenium/kg of diet), T-2 (5.0 mg organic selenium/kg of diet) and T-3 (10 mg organic selenium/kg of diet). The water quality parameters (temperature, DO, pH, conductivity, hardness, ammonia, nitrate and nitrite) were found to be insignificant (p > .05) among all the treatments. Superoxidase dismutase (SOD) was found to be significantly highest in T-2 (6.10 +/- 0.07) when compared with the other treatments. Similarly, catalase (CAT) activity in T-1 (13.21 +/- 0.13) was significantly (p < .05) different with that of Control, T-2 and T-3. Present study also revealed that 2.5mg organic selenium/kg supplemented diet (T-1) showed highest results in net weight gain (15.55 +/- 1.36 g), net weight gain percentage (185.88 +/- 8.98%) and SGR (2.35 +/- 0.06 g) compared with other experimental diet.
