Apparent digestibility by Nile tilapia <em>Oreochromis niloticus</em> (L.) of Brazilian-made meal, imported fish meal and toasted and spray-dried blood meals
Abstract
Apparent digestibility in Nile tilapia juveniles (100±10g) of imported fish meal, Brazilian-made fish meal, spray-dried blood meal and toasted blood meal was evaluated. While a semi-purified diet was prepared as control, four other diets containing about 35% of control diet and 65% of assay ingredients were prepared, using 0.10% of chromic oxide as indicator. Juveniles of Nile tilapia were randomly stocked in groups of fifty in circular cages. They were maintained for 8:00 to 17:00 p.m. in 250L-tanks and fed all day long. Later they were transferred to tanks 300L-tanks, appropriated for feces collection, in which they spent all night. Apparent digestibility coefficient of the ingredient was based on percentage of chromic oxide found in diets and feces and on nutrient percentage. Results indicate that spray-dried blood meal and the two fish meals may be used as a source of protein in Nile tilapia diets. Toasted blood meal cannot be recommended.Downloads
