【 摘 要 】

Aiming to evaluate the effects of including millet (Pennisetum americanum) in diets for piavuçu, Leporinus macrocephalus, were utilized 240 fingerlings with initial weight of 1.38±0.03g, distributed in randomized blocks with six treatments (0.00; 6.00; 12.00; 18.00; 24.00 and 30.00% of millet in diets) and five replicates, in 30 net ponds (120L) installed in five cement abestos tanks (1,000L), with eight animals in each net ponds. There was no effect of millet inclusion on the final weight, weight gain, apparent alimentary conversion, rate of efficiency proteic and survival of the fingerlings. Quadratic effect was observed for the cost/kg gain with the minimum cost at 20.31% of inclusion. It was concluded that millet can be included into 30.00% in substitution to the maize in diets for piavuçu fry, without affecting the performance.
