THE EFFECT OF EXPOSING BROILER HATCHING EGGS TO DIFFERENT PERIODS OF OZONE DISSOLVEDIN WATERON SOM HATCHING CHARACTERS, PRODUCTIVE PERFORMANCE OF HATVHED CHICKS

Abstract

The study conducted at the poultry breeding farm of the Animal Production Department, Faculty of Agriculture, University of Basra, aimed to investigate the impact of dipping broiler hatching eggs in ozone dissolved in water at varying durations on hatching qualities and the productive performance of hatched chicks. A total of 1,080 broiler hatching eggs Rose 308 were incubated, and six treatments were implemented with varying ozone exposure times. Hatching Ratio and Chick Weight: The results revealed a significant improvement (P < 0.05) in hatching ratio and chick weight for eggs treated with ozone compared to control treatments. The fourth treatment, with a two-minute ozone exposure, demonstrated the highest hatching ratio (89.73%) and chick weight (46.31 g), outperforming other treatments and controls
