Gene ANKRD55 is highly active in immune diseases, which corresponds to the state of the clinically diagnosed displaced abomasum cows used in this study, as studies have shown that cows with displaced abomasum are under active lipolysis, negative energy balance, and under higher infiltration of macrophages in adipose tissues (Hostens et al., 2012; Contreras et al., 2015). This evidence concerns the gene ANKRD55 and immune system disorder.
