Abstract

This study was conducted in the poultry field of the Department of Animal Production -
Agriculture College of - University of Basrah from 19/11/2022 to 17/12/2022, to investigate the
effect of feeding with different concentrations of ozone gas on some hematological and biochemical
traits of broiler chickens. A total of 225 unsexed one-day-old broiler chicks of the Ross-308 strain
were raised and randomly allocated to five experimental treatments, with 45 chicks per treatment and
each treatment content three replicates. The chicks were fed starter and grower diets. The first
treatment served as control, while the feeds for the other four treatments were sterilized with ozone
gas at concentrations of 6.6, 13.32, 19.98, and 26.66 mg/kg feed for the second, third, fourth, and
fifth treatments, respectively. The results showed no significant differences between the ozone
treatments and the control for both hematological traits and blood biochemical parameters.
Additionally, there were no significant differences between the control and ozone treatments in the
concentrations of liver enzymes AST and ALT. However, there was a significant decrease (P≤0.05)
in the cholesterol concentration for the fifth treatment compared to the control.
