Efficacy of Dietary Polyphenols Supplementation with Soybean Meal-Based Diet on Growth, Antioxidant Status and Carcass Composition of Labeo rohita Fingerlings

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 T with dietary supplementation of 150 mg/kg polyphenol showed significant (p
