After the infection, in the Fe-Gly addition group, the expression of hepatic FTL gene was significantly decreased (p < 0.05, Figure 5E), the expression of HAMP gene tended to decrease (p = 0.050, Figure 5D), and the expression of FTH gene had a tendency to decrease (p = 0.051, Figure 5F). This evidence concerns the gene HAMP and infection.
