^aFCR, FI and RFI represent daily feed intake, residual feed intake and feed conversion, respectively
^bChicken chromosome
^c* Indicates that the SNP P value reaches a genome-wise significance
^dAllele frequency of the first listed marker
^eEffect of allele substitution
^fU indicates that the SNP is upstream of a gene 5′-UTR
