Abstract : 1. A precision feeding experiment was conducted with turkeys, which were previously fed diets with or without phytase, to study the effects on the excretions of endogenous energy EEL, nitrogen ENL, amino acids EAAL and minerals. 2. Female turkeys BUT 6, which had been fed one of four experimental diets low P maize-soy diets control, C, C + 250 international units of phytase per kilogram diet FTU, C + 500FTU and C + 2500FTU were used in this study. All birds were fasted and then fed 50ml of glucose solution at 46 days of age. Birds were allocated to individual metabolism cages in a randomised block design with eight replicates for each of the four previously fed diets. 3. The response of EEL and ENL to phytase pre-exposure was a linear function P
