Transcriptomic profiling of jejunum mucosa of two laying hen strains in response to low dietary Phosphorus

This study investigated changes in gut transcriptome in response to the removal and reduction P (0 and 1 g P/kg feed) during the transition to egg production (at 19 and 24 weeks, before and after the onset of laying) in Lohmann Brown (LB) and Lohmann Selected Leghorn (LSL) chickens. A total of 80 LB and LSL hens were sampled in a 2x2x2 factorial design, encompassing two strains, age groups, and dietary.
