were significantly lower than those of eggs treated

Coufal also discussed published research that
demonstrates the efficacy of the hydrogen peroxide and
ultraviolet light treatment for sanitizing hatching eggs.
Sanitizing the eggs can increase the rate of hatch and
improve the quality of hatchlings. Hatching egg sanitation with hydrogen peroxide and ultraviolet light can
improve hatchability and performance of broilers.
