Biological interaction network of the proteins of differential abundance in the livers of broilers fed the probiotic E. faecium. Red lines indicate fusion evidence, green lines indicate neighborhood evidence, blue lines indicate co-occurrence evidence, purple lines indicate experimental evidence, yellow lines indicate text mining evidence light blue lines indicate database evidence, and black lines indicate co-expression evidence. ↑ and ↓ indicate up-regulated and down-regulated proteins in the livers of broilers fed the probiotic E. faecium, respectively
