Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the poultry industry, in particular to a method of increasing the embryonic and post-embryonic viability of chickens. The method comprises pre-incubation treatment of eggs with immunomodulator, and the treatment is carried out once by creation of gas-aerosol cloud of polyoxidonium solution in a confined space.

EFFECT: implementation of the method enables to increase the hatchability of eggs, to improve the safety of the chickens in post-embryonic rearing period.

Description

There are various methods of processing eggs: laser beams in combination with irradiation with a gas discharge lamp [1], a constant magnetic field - by placing eggs in a solenoid in a pulsed mode [2], optical radiation generated by an injection semiconductor source [3], an ozone mixture obtained with using a miniature ozonizer-ionizer design Storchevy V.F. [four].

There is also a method of processing hatching eggs with a solution of ribava, which is taken as a prototype [5]. It consists in the fact that Ribav is used twice on the surface of hatching eggs during embryonic development and when transferring aerosol from the spray bottle to the output. However, this method has several disadvantages: the need for special equipment (spray), the observance of the necessary concentrations, and also in connection with this considerable laboriousness. The cost of the drug is higher, because the drug is applied manually with a large overspending.

The objective of the present invention is to significantly increase the hatchability of eggs, improve the safety of chickens in the post-embryonic growing period by a single treatment of eggs with an aerosol cloud of the Polyoxidonium solution in a closed volume.

The method is as follows.

Polyoxidonium is diluted in water (10 ml per 50 ml of water). 2 hours before laying in the incubator, the resulting solution is treated with eggs once using a spray aerosol generator with an exposure of 20 minutes. The preparation for egg processing is consumed (DI) at the rate of 1.5 ml / m ³ per incubation chamber, regardless of its filling with the incubation material (eggs).

An aerosol cloud (fog) is created using a jet aerosol generator, filling the entire volume of the chamber in which the eggs are located.

Example 1. Eggs of chickens cross "Highsex brown" was obtained from one house, sorted 145 pieces per tray, subject to the same egg weight, time of laying and shelf life. An immunomodulator solution was applied to the shell surface in the form of a gas-aerosol cloud according to the above scheme. The data obtained are presented in table 1. Egg hatchability and chickens in the experimental batch increased by 3.4% and 2%, respectively, compared with the control.

Example 2. Chickens hatched from processed eggs (example 1) were grown in the same enterprise. The data are presented in table 2. The live weight of the daily chickens obtained from eggs treated with Polyoxidonium was 20.9% higher compared to the control group. Upon subsequent observation, the increase in live weight of the experimental group of birds exceeded the control by 5.5%. The safety of chickens in the period from 1 to 20 days of age was 2% higher compared to the control.

Example 3. In chickens hatched from eggs treated with Polyoxidonium solution, blood biochemical parameters improved (table 3). The results obtained allow us to conclude that Polyoxidonium stimulates metabolic processes in the body.
