In recent years, transcriptome analysis has been employed extensively applied to study of various species and traits ( Choi, et al, 2020 ; Cassar-Malek, et al, 2022 ; Jin, et al, 2022 ), Furthermore, it has been successfully employed in the study of poultry traits ( Ren, et al, 2021 ; Pham, et al, 2022 ; Sun, et al, 2023 ). Weighted gene co-expression network analysis ( WGCNA ) has also been widely used to identify key modules of traits and important genes in a multitude of species ( Fan, et al, 2023 ; Yu, et al, 2023 ).…”
