Description

The invention relates to poultry, and in particular to methods of increasing the resistance of young farm poultry, in particular chickens of egg productivity.

Known methods for increasing the resistance of chickens by irradiating eggs with laser beams (1) both separately and in combination with irradiation with a gas discharge lamp (2, 3), by performing acupuncture by perforating the nasal septum (4), by feeding the probiotic preparation Vetoma-3 (5 ), by pulsed electromagnetic irradiation of chickens (6), by irradiation of eggs with an optical study formed by an injection semiconductor source (7). All of the above methods have a serious drawback: they are quite expensive, and also require highly qualified personnel.

There is also a method of increasing the resistance of young animals by treating eggs with a one-ion mixture obtained using a miniature ozonizer-ionizer design V.F. Storchevy, which we took as a prototype. This method has several disadvantages: the complexity, the need for a device whose serial production has not been mastered (8).

The objective of the present invention is to increase the hatchability of eggs and the resistance of young chickens in the egg direction of productivity, expressed in their better growth and preservation, improvement of non-specific resistance, by repeatedly processing hatching eggs.

The technical result consists in the fact that the processes of embryogenesis are stimulated, the output of conditioned young animals is increased, and the mechanisms of its resistance are strengthened.

The technical result is achieved by performing triple processing of eggs with solutions of glycine and succinic acid, which are sprayed onto the surface of the egg shell, treatment before incubation and on the 7th day of incubation is carried out with a glycine solution, processing of eggs on the 19th day of incubation is carried out with a solution of succinic acid. Glycine is used in concentrations of 0.5-1.0%, and succinic acid in a concentration of 0.3-0.5%, the solutions of which are sprayed on 120-150 eggs 6-12 hours before incubation at an air temperature of 20- 22 ° C.

The method is as follows.

Glycine (aminoacetic acid) is dissolved in distilled water in concentrations of 0.5-1%. The resulting solution is applied to the surface of the egg shell. The treatment is carried out 6-12 hours before incubation, at a room temperature of 20-22 ° C. A similar treatment is carried out on the 7th day of incubation, during ovoscopy of eggs, in order to mitigate stress caused by a change in temperature On the 19th day - incubation, on transfer to hatchers, eggs are processed 0.3-0.5% - succinic acid solution. As a result, the safety of chickens is increased by 1-5%, the serum lysozyme content by 19-30%, the bactericidal activity by 12-40%, the content of lysosoyal-cationic proteins in granulocytes by 6-15%.

Example 1

The eggs of the Zarya-17 cross, obtained from one house for 4 days of collection (the hens of the parent herd 385-390 days), were sorted into trays. One batch of eggs served as a control, the other was treated with a solution of glycine before incubation and on the 7th day of incubation, as well as with a solution of succinic acid on the 19th day of incubation. The data are presented in table 1.

Example 2

The eggs of the Zarya-17 cross obtained from one house for 4 days of collection (the hens of the parent herd are 205-210 days) were sorted into trays. One batch of eggs was a control, the second was processed according to the same scheme as in the first example. The results are presented in table 2.

Example 3

Cross-country Rodonit eggs from one house for 2 days of collection (hens of the parent herd 210-212 days) were sorted into trays. One batch was a control, the second was processed according to the same scheme as in the previous examples. The results are presented in table 3.

As can be seen, in all examples, triple treatment of eggs increased the output of conditioned chickens by 4-7%, stimulated the immune system of the chickens, which was reflected in an increase in the bactericidal activity of serum (ALS) of the blood, the content of lysozyme and lysosomal cationic proteins (LKB) in granulocytes blood. The increase in bursa mass (Fabricius bag) indicated an increase in the functioning of this immunocompetent organ, which was confirmed by histomorphological studies. As a result of processing the eggs, the functions of the immunocompetent organs of the chickens were strengthened: the factory bag (bursa), spleen, and thymus. In chickens of the experimental group, an increase in the size of lymphatic follicles in the cortical and brain substances was found in bursa. Lymphoreticular hyperplasia, represented by young cells such as lymphoblasts, plasmoblasts and fibroblasts, was clearly visible in the medulla. At the same time, a large number of mitosis figures were noted.

In the spleen, a predominance of young cells was found, which are usually involved in the immunological process, increasing the body's resistance. As in the bursa, a clear picture of lymphoreticular hyperplasia was observed.

In the thymus of experimental chickens, the medulla was more clearly expressed in comparison with the control, and the blood vessels had a somewhat thickened wall with actively proliferating endothelium. An increased number of mitosis figures was also noted compared with the control. In general, in comparison with the control, enhanced reproduction of cells of the lymphoid plasmacytic series in the brain and partially in the cortical layer of the thymus was seen.

From the above data it is seen that the proposed method for the use of glycine and succinic acid allows to achieve the purpose of the invention, that is, it allows to increase the resistance of hatched chickens in the claimed methods and doses of the use of these preppsias.
