SAAD, Carlos Eduardo do Prado; FERREIRA, Walter Motta; BORGES, Flávia Maria de Oliveira  and  LARA, Leonardo Boscoli. Nutricional evaluation of commercial foods and sunflower seed for blue-fronted parrot (Amazona aestiva). Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp.1493-1499. ISSN 1413-7054.

In this experiment twelve adult parrots were used in a randomized block design distributed in six treatments (T1- Extruded food for psittacines-A, T2- Pellet food for psittacines-B, T3- Extruded food for psittacines-C, T4- Dog food premium line, T5- Dog food economic line and T6- Sunflower seed) during three harvest periods, in six replication for treatment. The values of apparent and true metabolizable energy (AME and TME) were determined and they were corrected by nitrogen (AMEn and TMEn), nutrients digestibility coefficients (GE-Gross Energy, OM-Organic Matter, CF-Crude Fiber and EE-Ether Extract), nitrogen balance and metabolizable protein. The data were analyzed by SNK test. The results allow to conclude that: 1) the values of AME e TME were higher than AMEn and TMEn; 2) the sunflower seeds showed the higher apparent and true digestibility of the dry and organic matter; 3) the lipids digestibility of all diets was high ( 92,62% in average) 4) The nitrogen balance (apparent and true) was positive for all parrots.

Keywords : Digestibility; metabolizable energy; nitrogen balance; psittacines.
