^aHigh RFI is feed inefficient and low RFI is feed efficient

^bGene expression values were calculated by normalizing cycle threshold (Ct) values for target genes to Ct values of the reference genes after adjustment for efficiencies and interplate variation and converted to values relative to the mean Ct value within each data set using GENEX (MultiD Analyses, AB, Gothenberg, Sweden)
