CS199179B1 - Method of increasing of incubation efficiency through centrifugation of eggs to be hatched before incubation - Google Patents

Description

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

At the present time, eggs are stored in a quiet at least a hazelnut or pad at a temperature of 8 to 12 ° C according to ČSN 466409 before hatching. Also, at certain times of the year or in the lay cycle, the stigma of the chickens has been significantly reduced. Bias E.I., Smith A.H., Walker M. W., Appl. Physiology 20: 1965.

The above-mentioned non-leakage removes the invention, which is characterized in that the hatching eggs are centrifuged for 10 to 120 minutes with an intensity of 4 to 10 G.

Starting the hatching eggs prior to the start of the hatching will positively influence the further development of the embryo and hence the increased hatchability.

Example 1

Fertilized hen eggs were centrifuged in a sponge-treated centrifuge for 10 to 120 minutes. The effect of 4G hypergravity is shown in Table 1.

Example 2

Fertilized eggs of Japanese quails and centrifugovall in a specially treated oentrifuge for 10 to 60 minutes with a hypergravity intensity of 4 Q and 10 0,

Example 3 /

He investigated the effect of hypergravity on hatching eggs of Japanese preweed and decreased biological value. After centrifugation at 40 ° C for 10 minutes e increased the fertility of fertilized eggs by an average of 54.8% to 76.9%. The difference was statistically proven.

The invention may be used to treat hatching eggs prior to hatching in a hatchery, thereby substantially increasing the hatching rate.
