ABSTRACT
The study considers the influence of non-ionic radiation (white and monochromatic light) on the hatching of the Hampshire breed chickens. The chicken embryos were most sensitive to the white light (E1), reaching the hatching time of 503.63 ± 3.17 h, the hatchability of 95.12 ± 3.72% and an average weight of incubated chickens 46.83 ± 2.82 g. Of the monochromatic lights, the chicken embryos were most sensitive to yellow and green lights (E5, E4) with the hatching time of 505.22 ± 4.03 and 507.14 ± 3.95 h, respectively, the hatchability of 94.89 ± 3.02 and 94.47 ± 2.93%, respectively and the average weight of incubated chickens 45.72 ± 1.93 and 45.05 ± 2.66 g, respectively. The least reaction of chicken was observed with violet light (E2) with the hatching time of 510.04 ± 1.97 h, hatchability of 90.81 ± 4.05% and the average weight of incubated chickens 42.02 ± 3.72 g. The effect of violet light brings the same results as we observed in the case of hatching in darkness (control group C), when the hatching time was 510.41 ± 2.82 h, hatchability 90.42 ± 3.35% and average weight of incubated chickens 41.98 ± 3.05 g.
