Transcriptome profiling of the jejunum mucosa of two laying hen strains at five time points spanning egg production phases during 10 to 60 weeks of age

In this study, we deep-sequenced the transcriptomic profile of the jejunum mucosa in two laying hen strains (Lohmann Brown-Classic and Lohmann LSL-Classic) at 10, 16, 24, 30, and 60 weeks of age. These five time points span the initial, peak and end of the lay periods in which the hens critically experience physiological changes and need optimal diets to meet both growth and egg production requirements. Therefore, a comparative transcriptome profiling of the jejunum mucosa may lead to a better understanding of molecular mechanisms underlying genetics, age and nutrition factors of layers.
