Values are mean ± SE for 8 chicks/group

Hydrogen peroxide was added to drinking water of one-day-old chicks and continued for 14 days.

^*Significantly different from the respective control value, p<0.05.

^aSignificantly different from the respective 7-day-old group, p<0.05.

^bSignificantly different from the respective 10-day-old group, p<0.05.
