Abstract :The effects of ozone (O₃) treatment for disinfecting hatching eggs on hatching results were investigated in this study. A total 264 eggs were used which were from an Australorp chicken flock which was at 52 weeks of age. O₃ was given to eggs as gaseous and sprayed in water. Gaseous O₃ treatment significantly decreased the bacteria count on the eggshells (P<0.05). Total bacteria count was 4.38 log10 CFU/egg on gaseous O₃ treatment, while 4.97 log10 CFU/egg without O₃ treatment. The highest incubation egg weight loss (10.09 %) occurred in the eggs sprayed with ozonated water. O₃ treatment significantly reduced the hatchability. Gaseous O₃-treated and O₃-sprayed eggs had 16.91% and 50.41% hatching rates, respectively. No O₃-treated eggs had the highest hatchability (76.03%, P<0.05). Embryonic mortalities at different incubation periods were significantly higher in O₃-treated groups than in the control group (P<0.01). The longest hatch window occurred in O₃-sprayed eggs, and total hatching time (defined as the interval between the first and last chick hatch) was 78 hours. Giving O₃ as gaseous has prolonged the hatching.
