Enriched KEGG pathways derived from the differentially expressed genes (DEGs) with higher expressions observed in LB (blue) or LSL (yellow) when comparing LB and LSL laying hen strains (A), as well as enriched KEGG pathways based on the identified DEGs with higher expressions observed at 19 weeks (blue) or 24 weeks (yellow) when comparing maturation effects, i.e., the two age groups (19 vs. 24) (B).
