Efficacy of vitamin e and selenium on brood stock management and reproductive performance of rohu Labeo rohita (HAM.)

Abstract

The study was conducted to assess the breeding performance of Labeo rohita (Ham.) by supplementing different concentration of vitamin E and selenium in the formulated diets. Test diets with 25.50% protein were developed using fish meal, ground nut oil cake, rice bran, black gram, horse gram, broken rice and maize. The diets supplemented with different concentration of Vitamin E and selenium viz., diet I with no supplementation of vitamin E and selenium referred as control feed, 62.5 and 125; 125 and 250; 250 and 500; 500 and 1000 mg/kg and ppm of Vitamin E and Selenium respectively and referred as diet II, III, IV and V. The Gonadal Somatic Index, fecundity, Ova diameter, fertilization, hatching and survival percentage were studied. Diet supplemented with 250 mg vitamin E and 500ppm selenium shows better result. The least performance was observed in control diet.
