Therefore, it could be assumed that Balangut LS P triggered the immune system by shifting the expression of immune-related genes of IL-21R, ZAP70, and DUSP4 to respond to pathogenic infection, possibly recovered the intestinal environment during the recovery phase and inclined energy sources from immunity to the growth, as evidenced by a lower FCR in this treatment at finisher phase. Here, DUSP4 is linked to infection.
