Description

The invention relates to the field of agriculture and, in particular, poultry farming.

Mitomin is a drug that includes succinic, ascorbic acid and fructose in its composition.

It is known to use UC solutions by immersion to stimulate the embryonic development of chickens [1].

This method, taken by us as a prototype, consists in the fact that hatching eggs laid in trays are immersed in a 0.05% aqueous solution of UC. However, this method has several disadvantages: the irrational use of drugs, contamination of the solution, the complexity of the process, as well as the low-tech processing of eggs.

The purpose of the invention is to increase the hatchability of eggs and the withdrawal of conditioned chickens with a high level of natural resistance by a single treatment with a mitomine solution.

The method is as follows.

Mitomin is dissolved in distilled water at a concentration of 0.3-1.5%. The resulting solution is applied to the surface of the egg shell with a spray at the rate of 2.2-2.5 ml per 120-150 eggs. The treatment is carried out 6-12 hours before incubation at a room temperature of 20-22 ° C.

Example 1. The hatching eggs of the cross "Highsex white", obtained from one parent herd, subject to equality of weight, time of demolition and shelf life. The number of eggs in each batch was 459 pcs. 12 hours before incubation, they were sprayed with an aqueous solution of mitomine of different concentrations from 0.5 to 1.5%. Eggs of the same batch were used as control. The data obtained are presented in table 1. The hatchability of eggs and hatching in the 1st and 2nd experimental batch increased by 7.4% (p <0.05) and 4.9%, respectively; 4.2% and 3.9% compared with the control. With an increase in the concentration of mitomine to 1.5% (3rd experimental), the indicator of hatchability of eggs did not change and the output was 2.4% less than in the control.

Example 2. Eggs of chickens cross "Highsex white", obtained from one house with a shelf life of 10 days, sorted into trays. The number of eggs was 306 pcs. Sprayed according to the scheme (example 1) with an aqueous solution of mitomine in concentrations from 0.3 to 1%. The eggs of the same batch served as control. As a result of the experiment, hatchability and hatching increased by 7.6-17.5% (p <0.001) and 8.9-21.3% (p <0.001), respectively, compared to the control. In this case, the optimal concentration is set from 0.3 to 0.5%. The data obtained are presented in table.2.

Example 3. To confirm the data, eggs of cross chickens “Hysex white” with a shelf life of 14 days were sorted into trays. The number of eggs in each batch was 306 pcs. The processing according to the scheme (example 2) was repeated. The data obtained are presented in table.3. As studies have shown, hatchability and hatching increased by 4-15.4% (p <0.001) and 3.2-13.4% (p <0.001) compared with the control.

Example 4. Chickens hatched from eggs treated with a 0.5% aqueous solution of mitomine were placed in typical windowless houses under the same conditions. The poultry content was in accordance with NTP-APU, 2001. The control and experimental groups were formed, respectively formed from the control and the best experimental batch, 100 animals each. It was found that the death rate of chickens for 67 days of rearing in the experimental group was 1.5 times less than in the control group (Table 4).

Example 5. In day-old chickens hatched from eggs treated with a 0.5% aqueous solution of mitomine (Example 1), some biochemical parameters of blood serum improved. So, the content of glucose increased by 1.5 times, albumin by 19.7% and total protein by 6.7% compared with the control (Table 5).
