WLA: high performing White Leghorn; BLA: high performing Rhode Island Red; R11: low performing White Leghorn; L68: low performing New Hampshire; LA, AA, HA: low, adequate and high L-arginine supplied diets; PSEM: pooled standard error of means; GT: genotype

^A–C

LSMeans values with PSEM (n=3chicks/group) of one organ in the same column without common superscripts differ significantly (p<0.05)

^a–d

LSMeans values with PSEM (n=3chicks/group) in the same row without common superscripts differ significantly (p<0.05)
