Abstract

The present study had as objective to evaluate the effects of vitamin C supplementation on the performance indices of bullfrog (Rana catesbeiana) tadpoles. The tadpoles, with an average weight of 12.3 ± 2 mg, were distributed in 16 boxes (40 L), with 1 tadpole L-1. They received diets supplemented with zero (control), 1,000, 1,500 and 2,000 mg of vitamin C kg-1 of diet, during 75 days. After this period, the survival, metamorphosis percentage, weight gain and specific growth rate were evaluated. The tadpoles that received 2,000 mg vitamin C kg-1 ration showed the best results in survival (93%), the best percentage of metamorphosis (29%), the greatest weight gain (4.22 g) and the best specific growth rate (6.03% day-1). The worst performance was observed in the tadpoles that did not receive vitamin C. The results suggest that ration with 2,000 mg of vitamin C kg-1 improves weight gain, specific growth rate, metamorphosis and survival of the bullfrog tadpoles.
