Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and, in particular, to the poultry industry. The method is characterized in that on the surface of the shell of poultry eggs 3-4 hours prior to the incubation the aqueous solution of succinic acid and glycine in a concentration of 0.01% is applied from the sprayer. When transferred into breaking the eggshell on the 19th day of incubation, the 0.5% solution of succinic acid is applied, based on 2.5-2.7 ml per 120-150 eggs at the solution temperature of 20-22°C.

EFFECT: invention enables to increase hatchability of eggs, to reduce the mortality of young birds, to normalize the level of metabolic processes, to reduce labour costs and consumption of products.

Description

The invention relates to the field of agriculture and, in particular, to poultry farming (the use of solutions of succinic acid (Yak) and glycine (Hl)).

The use of these drugs to increase the hatchability of eggs and the resistance of chickens of egg crosses is known [1].

This method, which we took as a prototype, consists in the fact that the hatching eggs were subjected to processing: with 1% Hl solutions twice before incubation and on the 7th day, and with a 0.5% Yak solution when transferring eggs to hatch. Moreover, the hatchability of eggs exceeded the control by no more than 0.2-7.0%. The disadvantage of this method is the significant labor costs (three times processing) and the use of high concentrations of glycine (1%).

The objective of the invention is to increase the hatchability of eggs and improve the safety of chickens in the postembryonic period by treating them twice before incubating a 0.1% complex solution of Yak + Hl, and when transferring to a conclusion of 0.5%, a solution of Yak.

The technical result consists in the fact that the hatchability of eggs is increased, the waste of young animals is reduced, the level of metabolic processes is normalized, labor costs and drug consumption are reduced in comparison with the prototype.

The technical result is achieved in that the eggs are treated twice before incubation with a solution (succinic acid + glycine), and when transferred to the conclusion (on the 19th day of incubation), a 0.5% succinic acid solution is used.

The method is as follows.

3-4 hours before incubation with a spray, a 0.1% aqueous solution of the complex of drugs (succinic acid + glycine) is applied to the surface of the egg shell, and when transferred to the conclusion (on the 19th day of incubation), a 0.5% solution of succinic acid from calculation of 2.5-2.7 ml per 120-150 eggs at a solution temperature of 20-22 ° C.

Example 1. Eggs of chickens cross "Highsex white" was obtained from one house, sorted 145-150 pieces per tray, subject to the similar egg weight, time of laying and shelf life. The number of eggs in each batch is 300 pieces. Solutions of the drug in distilled water were applied to the surface of the shell according to the above scheme. As a control, eggs of the same batch were selected, which were not processed with this preparation. The data obtained are presented in table 1. Egg hatchability and chickens in the experimental batch increased by 9.66% and 9.67% (p <0.001), respectively, compared with the control.

Example 2. Chickens hatched from processed eggs (example 1) were grown under the conditions of the same farm until 60 days of age. The data are presented in table 2. The chick waste for 2 months of rearing decreased by 3.5 times compared with the control.

Example 3. In chickens hatched from treated eggs, at a daily age, a biochemical study of blood serum showed an increase in the normal protein content by 9.45%, AlAt and AsAt by 1.90 and 1.69 times, as well as glucose 1.65 times and α-amylase 1.5 times compared with the control. In other indicators, the differences were insignificant (tab. 3)
