The invention relates to the field of agriculture, particularly poultry (aerosol application solutions "Ribas").

It is known the use of the drug to stimulate the immunological reactivity and productivity of ducks and chickens-broilers, method of feeding [1, 2]. Other ways of using this drug the bird is not registered.

This method, taken as a prototype, is that "Ribas" was applied only during postembryonic development, by feeding it with water at critical periods in the life of chickens. Therefore, the hatchability of eggs obtained from hens of the experimental groups outperformed the control no more than 4.1%, and preservation of chickens within 2 months of cultivation did not exceed 4.2 per cent.

The objective of the invention is a significant increase in hatchability of eggs, and improve the safety of the chickens in the post-embryonic period by two aerosol processing solutions "Ribas".

The technical result is that increasing the hatchability of eggs, reduced waste of young, normal level of metabolism, the authors estimated the effect increases activity in the serum of chickens.

The technical result is achieved by the fact that the treatment is carried out twice in the period of embryonic development, namely 3-4 hours before incubation aerosol spray on p is the surface hatching eggs cause of 0.005%solution of the drug "Ribas" and when transferring to a conclusion - of 0.25%.

The method is as follows.

On the surface of shell eggs poultry 3-4 hours before incubation of the spray is applied aqueous solution "Ribav in concentrations of 0.005% and before the transfer to the conclusion of 0.25%. Previously the drug dissolved in distilled water at 18-22°C.

Example 1. Eggs of the cross "Hisexs white" was received from one of the house, sorted by 145-150 pieces on the tray by observing the similarity of egg weight, time of demolition and retention. The number of eggs in each batch of 300 pieces. On the surface of the shell struck in the form of an aerosol drug solution under the above scheme. As a control were collected eggs of the same batch, which was treated according to the technology sector. The obtained data are presented in table 1. The hatchability of eggs and chick in experimental batches increased by 9.34 and 11.0% (p≤0,001) compared to control.

Example 2. Chickens derived from treated eggs (example 1), were grown in the farms of up to 60 days of age. The data presented in table 2. Waste Chicks 2 months of cultivation decreased by 5.0% compared to control.
