| Popis: | Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Two experiments were accomplished to study the crude fiber effect on the growth, digestive parameters, and yield and carcass quality of jundiá (Rhamdia quelen) juveniles. Six treatments were evaluated (3 replications) in which 2 sources (soy hull and cotton hull) and three levels of crude fiber (4,7,10%) were tested. In the first trial (120 days), 450 fish (129,11±7,8 g) were randomly distributed in 18 net cages with 1m3 at densities of 25 fish/cage, in 0.1 ha earth fishpond to verify the growth performance: weight, total length, weight gain (g/day), biomass, survival, carcass and fillet yield, digestive and hepatic-somatic indexes, intestinal quotient, with the chemical composition values of fillet, protein and fat deposition on fillet were calculated. No difference was detected in the growth performance. Fish fed with soy hull diets presented more fat and mineral accumulation on fillets (P |
