SUBSTITUIÇÃO DA FARINHA DE PEIXE POR FARINHA DE VÍSCERAS DE AVES NA ALIMENTAÇÃO DO PIAVUÇU Leporinus macrocephalus

Abstract

The present study aimed at evaluating the productive performance of Leporinus macrocephalus fed with different levels of inclusion of poultry viscera meal replacing fish meal. The experiment was conducted in a stove located in the Universidade Estadual do Oeste do Paraná during 45 days. We used 200 fish with average initial length of 4.7 ± 0.37 cm and average initial weight of 1.407 ± 0.03 g, distributed in 20 net-cages. The experimental design was randomized with five treatments and five replicates with five levels of replacement of fish meal by poultry viscera meal (0, 25, 50, 75, 100%). The parameters evaluated were the productive performance and the chemical composition of animals. The inclusion of poultry viscera meal in the substitution of fish meal in the feeding of Leporinus macrocephalus can be used without impairing the performance of the animals.
