In recent years, was found that factors such as ultraviolet and visible rays, laser irradiation, air ionization, magnetic field and their combination can stimulate the metabolic processes in biological objects, for example, improve the quality of hatching eggs, output and viability of young birds. For eggs sanitation processing are used different modes with different intensities of irradiation. It was formed two experimental groups and one control group in hens’ eggs and two experimental and one control in quail eggs. Incubation results showed that maximum hatchability of hen eggs were obtained in experimental groups and it were 95.1% and 92.6% also compared with the control group increased by 5.5% and 3.0%. The experience developed with quail eggs in the same experimental groups the hatchability were 93.5% and 93.7% or 3.3% and 3.5% higher compared with control. Maximum effect in experiments with chicken eggs proved to be covered by continuous irradiation mode with a duration of 10 min., and in the experience with quail eggs maximum effect was in the experimental group where was used fractionated irradiation mode with a duration of 10 min.
