Through integration of previous research findings with GO and KEGG enrichment results, we identified seven key candidate genes potentially influencing early growth traits in IMCGs: ZN845, SOX15, FGF11, GPS2, DVL2, SPRY4, and STAT2. Considering that weight gain in animals is closely associated with muscle development, fat deposition, and obesity (3), Functional enrichment analysis was conducted for these seven candidate genes. Here, STAT2 is linked to obesity due to melanocortin 4 receptor deficiency.
