Abstract

FIELD: veterinary medicine.

SUBSTANCE: egg albumen is diluted in water and is additionally filtered. Before laying eggs in the incubator they are treated once in a closed volume. The treatment is carried out by creation of gas-aerosol cloud of egg albumen solution with exposure of 15 minutes.

EFFECT: increase in hatchability of eggs and improvement of safety of chicks in postembryonic rearing period.

Description

The invention relates to agriculture, in particular to poultry farming, namely to pre-incubation processing of eggs.

There are various methods of treating hatching eggs: degassed water [1], mitomine solution [2], ozone, succinic and para-aminobenzoic (PABA) acids [3].

There is also a method of processing hatching eggs with a solution of limontara (a mixture of citric and succinic acids), which we have taken as a prototype [4]. It consists in the fact that the eggs on the first day of incubation are treated immediately before laying and on the 19th day of incubation in the amount of 80 ml per 140 pieces of incubated eggs. Before laying them in an incubation cabinet, 0.25 is used, and when transferring a 0.55% solution of limontara to the output. However, this method has several disadvantages: careful observance of the necessary concentrations, considerable laboriousness.

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

The method is as follows.

Egg white is diluted in water (protein 1 egg per 500 ml of water), additionally filtered. A few hours before laying in the incubator, the eggs are treated with the resulting solution once using a spray aerosol generator with an exposure of 15 minutes. The preparation for egg processing consumes 100 ml per incubation chamber, regardless of its filling with the incubation material (eggs).

Example 1. Eggs of chickens cross "Highsex brown" was obtained from one house, sorted at 126 pieces per tray, subject to the same egg mass, laying time and shelf life. An egg white solution was applied to the surface of the shell 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 4.8% and 5.6%, 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 egg white was 11.4% higher compared to the control group. At 10 days of age, the live weight of the birds of the experimental group exceeded the control by 6.57%. The safety of chickens in the period from 1 to 20 days of age was 6% higher compared to the control.

Example 3. In chickens hatched from eggs treated with an egg white solution, blood biochemical parameters improved (table 3). The results obtained allow us to conclude that the egg white used by the SAGO cloud at the stage of pre-incubation processing stimulates metabolic processes in the body.
