Effect of 50 Hz magnetic field on chicken embryo development and course of hatching

The effect of additional extremely low frequency (ELF) magnetic field (50 Hz) on the development of chick embryo was investigated. The experiment was carried out in three variants for induction values 15, 10 or 5 μT. Magnetic field (MF) in the experimental incubator was generated by a set of three Helmholtz coils. The following analyses were performed: embryopathological analysis; evaluation of the hatched chicks for quality; analysis of the course and synchronization of hatching Early embryo mortality in groups exposed to MF 10 and 15 μT compared to the control was higher by about 3 percentage points. Simultaneously, in these groups the hatching processes accelerated, but the quality of hatched chicks was much lower.
