The aim of the current experiment was to determine the aP requirements in modern broilers by performing a dose-response experiment. This study showed that for realizing maximal performance, in phase 1 (d1-d10) 5.4 g aP per kg of feed was required, in phase 2 (d11-d21) 4.3 g aP per kg of feed, and in phase 4 (d31-d38) 2.6 g aP per kg of feed. In phase 3 (d22-d30), performance of the broilers was not affected by dietary aP content. For realizing maximal tibia ash content in phase 3, an aP-level of 3.8 g/kg was required.
