Phosphorus requirement in laying hens

W. Lambert, M.M. van Krimpen, L. Star

Research output: Book/ReportReportProfessional


It was hypothesized that P supply by feed in alternative housing systems can be lowered without negative effects on bone quality and production performance. Therefore, the objectives of the current study were 1) to update the retainable phosphorus (rP) needs of two modern laying hen breeds from 36 to 90 weeks of age housed in an aviary system, 2) to investigate the influence of dietary rP levels on Ca and P content in eggs, manure, carcasses and bones.
