ABSTRACT
A 70-days growth trial was carried out to ascertain how dietary supplementation of polyphenols with soybean meal-based diet influences the growth, antioxidant status and carcass composition of Labeo rohita fingerlings. Seven experimental diets were formulated with graded levels, 0, 50, 100, 150, 200, 250 and 300 mg/kg of polyphenols supplementation. Each test diet was allocated randomly to triplicate tanks with 15 fingerlings in every tank. These were fed @ 5% of live wet body weight. Results showed that L. rohita fingerlings fed on test diet T4 with dietary supplementation of 150 mg/kg polyphenol showed significant (p<0.05) increase in growth performance having weight gain% (233.24%) and better feed conversion ratio (1.44). Similarly, significantly (p<0.05) improved body composition with crude protein (17.96%), crude fat (8.72%), ash (4.94%) and moisture (68.43%) were also recorded at same polyphenols supplementation level. However, in terms of antioxidant activity, increasing trend in inhibition of oxidation was recorded with increase in supplementation of polyphenols in test diets, having minimum oxidation (7.66) in fingerlings fed on T7 with 300 mg/kg level of polyphenols supplementation.
