Abstract :

Previous research has indicated that a single exposure of eggs to Ultraviolet Light (UV) in combination with 3% hydrogen peroxide (H2O2) results in a greater reduction of eggshell microorganisms compared to eggs treated with either UV or H2O2 alone. The objective of this study was to determine if hatchability would be affected if eggs were treated by repeated applications of UV and H2O2. In the first experiment, eggs receiving H2O2 and UV light for 2 min 6 times yielded the greatest reduction in aerobic plate counts (5.3 log10CFU/egg) when compared to other treatment groups that utilized various repetitions of H2O2 and UV light. The second experiment determined the effect on hatchability when using this combination tested in Experiment 1. In Experiment 2, a 4 log10CFU/egg reduction in eggshell aerobic plate counts was observed for eggs treated with UV and H2O2 when compared to untreated control eggs. There were no differences in hatchability, hatch residue, chick weight, residual yolk weight, or egg weight loss between control and treated groups. In conclusion, multiple applications of UV and H2O2 effectively reduced aerobic microorganisms on the eggshell to low levels with no detrimental effects on broiler breeder egg hatchability or chick quality parameters.
