Avaliação do gasto e Consumo voluntário de rações balanceadas e semente de girassol para papagaios-verdadeiros (Amazona aestiva)

Abstract

Were used 12 adult parrots, distributed in blocks in six treatments (Extruded food for psittacines, Pelleted food for psittacines, Extruded commercial food for psittacines, Extruded dogs food premium line; Extruded dogs food economic line and Sunflower Seed). during three periods, in six repetitions for treatment. The total expense (dry matter evaporates - DM and natural matter - NM) and intake of NM, DM, crude protein (CP) apparent and true metabolizable energy N corrected (AME n and TMEn), calcium (Ca) and phosphorus (P), was evaluated for bird and for kilogram of metabolic size. The data were collected in three experimental phases of five days each, and previously to each phase an adaptation of seven days was accomplished to the experimental diets. The averages were compared by the SNK test. The obtained results allowed to conclude that: 1 - the medium consumptions of DM were influenced negatively by the metabolizable energy of the diet; 2 - the high intake of the birds receiving sunflower seed suggests that, besides the energy density, the flavor of the diet has great influence in the voluntary feed intake; 3 - all the tested diets reach the daily requirement of crude protein; 4 - the calcium intake of the sunflower seed did not reach the daily requirement of this nutrient, 5- the bigger pellet size seems to influenced negatively the total waste of parrot food.
