Transcriptomic insight into the underlying mechanism of induced molting on reproductive remodeling, performance and egg quality in laying hen.

ABSTRACT: This study aimed to clarify the reproductive remodeling mechanism in enhancing production performance and egg quality during the fasting-induced molting process of laying hens. A total of two-hundred and forty 380-days-old Jingfen No. 6 laying hens, with an average laying rate of 78% were divided into four replicates, with 60 hens in each replicate to receive a four-stage molt induction experiment. The stages encompassed the pre-molt stage (T1), the molt stage (T2), the recovery stage (T3), and the second peak-laying stage (T4). The egg-laying rate and egg quality were recorded during all stages, and sample collection (serum, magnum of oviduct, ovary) was conducted at the end of each stage. The length and index of oviduct, the number of hierarchical follicles, and serum reproductive hormon
