【 摘 要 】

The present research aimed at evaluating the inclusion poultry by products of birds viscera flour (FV) in the feeding of piavuçu (Leporinus macrocephalus) fingerlings. 125 fingerlings with weight and medium initial length of 0.26±0.01g and 2.37±0.28cm, respectively were used, distributed in 25 aquariums (30 liters water capacity each) in an entirely casualized delineation with five treatments and five repetitions. The rations were formulated in way to contain 0; 5; 10; 15 and 20% of FV, being the same isoenergetics and isoproteics. The feed giving was realized four times at 8, 11, 14 and 17 hours, with base in 10% of the total biomass. The zootechnics parameters evaluated were the final weight (PF), final length (CF), weight gain (GP), apparent alimentary conversion (CA) and survival (SO). There were observed an increase in the lineal differences (P<0.05) in the PF, CF, GP averages and CA with increase in the level of inclusion of FV. The SO and FC didn't present difference (P>0.05) among the treatments. The increase in the inclusion of FV in rations up to 20%, improves the piavuçu fingerlings performance.
