Intake of metabolizable energy in adult canaries (serinus canaria)

Abstract

The assay accomplished to determine the optimum level of metabolizable energy(ME) for the canary maintenance using diets with crude protein(CP) level growing (12%, 15% e 18% in natural matter - NM) combined with three level of ME (2700, 2850 and 3000 kcal/Kg in the NM). 54 birds (Serinus canaria) were used, distributed at random in nine treatments (three level of protein and three level of energy), 18 experimental units, with four periods, eight repetition as a balanced incomplete block desing. The parameters studied were 1- average daily intake ME; 2- digestibility coefficient of GE; 3- relation ME:CP of tested diets. Was used the student "t" test (dms) to compare the effects of protein level, metabolizable energy level and its interactions. The results obtained in this experiment they allowed to end that: - canary in maintenance had their intake metabolizable energy influenced by the level of crude protein, suggested that the (14,55 kcal de ME/birds and 15%CP in diets with a relation of 18 kcal ME/g CP).
