Control is the noninjected treatment. Saline is 1 mL/kg BW physiological saline (0.75%) injected treatment. 2.5%H₂O₂, 5%H₂O₂, and 10%H₂O₂ are H₂O₂ treatments injected with 0.74, 1.48, and 2.96 mmol/kg BW H₂O₂ solution per bird.

SEM: pooled standard error of means.

^a,b,c

Means within a row with no common superscripts differ significantly (P < 0.05), n = 8.
