CS210995B1 - Method of treatment of eggs to be hatched for increasment of hatching property of poultry - Google Patents

Description

The invention relates to the treatment of eggs prior to hatching.

Presently, eggs are stored in the quiescent state on hazelnuts or mats at 8 to 12 ° C according to ČSN 466 709 prior to hatching. the biological value of hatching eggs and hatching.

This drawback removes the invention, which is characterized in that hatching eggs are subjected to a homogeneous stationary magnetic field with an induction of 0.3 T for 10 to 60 min.

The application of the magnetic pole to the hatching eggs prior to loading into the hatchery favorably affects the further development of the embryo and causes an increase in the yield.

For example,

The fertilized eggs of Japanese quails were subjected to a homogeneous stationary magnetic field induced by an electromagnet with circular pole extensions of 10 cm diameter at a half-magnet distance of 6-10 cm for 10-120 min. The effect of 0.3 T induction of the magnetic pole is shown in Tab. no. First

After multiplication of the magnetic pole with induction of 0.3 T in 10-30 min, the hatching of fertilized eggs increased from 76.1% to 85.4, in 40-60 min from 76.1 to 87.8%, in 120 min from 76.1 7 to 81.3 7,. After multiplication of the magnetic pole for 40-60 min the difference was statistically significant (P = 0.02) - tab. no. First

Example

The effect of homogeneous stationary magnetic pole on hatching eggs of Japanese quails with decreased biological value (older than 9 days) was studied. Incorporation of the magnetic pole with induction of 0.3 T for 10-30 minutes increased the hatching rate from 57.8% to 75.3 Z, in 40-60 min from 57.8% to 79.7 X. The difference was statistically high P = 0.01 / tab. no. Second

The present invention can be used to treat hatching eggs prior to being placed in the hatchery to achieve a substantial increase in hatching.
