Description

Field of technology to which the invention relates

The invention relates to animal science, in particular to a method for incubating quail eggs.

State of the art

Currently, many scientists are working to develop and improve new methods of incubation and processing of eggs.

There are known methods of using pine needle preparations in veterinary medicine for disinfection. In this case, the following is used: a preparation containing formalin and an aqueous extract of Siberian fir needles (patent KZ 23110 dated November 15, 2010); 2-4% coniferous balsam fir complex (Coniferous substances for agriculture. - (http//www. solagift. Ru/page_id=61))

The disadvantage of this method is that it is intended for disinfection and deodorization of air in livestock buildings in the presence of farm animals and is not used for disinfection of hatching eggs. In addition, one of the proposed drugs contains formaldehyde, which can lead to the death of embryos when processing hatching eggs.

The prototype is a method for disinfecting hatching quail eggs (patent RU 2736327, IPC A61D 7/00 (2006.01), IPC A61D 99/00 (2006.01); SPK A61D 7/00 (2020.08), IPC A61D 99/00 (2020.08) publ. 11/13/2020, Bulletin No. 12) In which hatching quail eggs are subjected to aerosol treatment of the eggs with a 10% aqueous solution of the coniferous balsam fir complex at the rate of 100 ml per 1 m2 of tray, exposure 60 minutes, the first treatment is carried out before incubation, then on 15.5 days of incubation.

The disadvantage of this method is that the balsam fir complex contains oils, which can lead to clogging of the pores of egg shells.

There is a known method for incubating farm poultry eggs (patent RU 2338370, IPC A01K 41/00 (2006.01) publ. November 20, 2008, Bulletin No. 32.) including changing the temperature in the incubator depending on the age of the embryo. In the second half of incubation from days 15 to 18, the temperature is set at 37.28-37.32°C, and during the hatching period from days 19-21 - 36.78-36.82°C.

The disadvantage of this method is that in the second half of incubation the maintained temperature is low for incubation of quail eggs, which can lead to underheating and death of the embryo.

The closest in technical essence and the achieved positive effect and accepted by the authors as a prototype is the method of incubating quail eggs, which is used in the incubation workshops of quail farms (recommended by Z.I. Kochetova, L.S. Belyakova. Quail farming - cultivation and maintenance, Sergiev Posad , 2012, 84 p.)

The disadvantage of this method is maintaining a temperature of 37.6-37.7°C for up to 12 days, which can adversely affect the development and safety of the embryo after allantois closure.

Disclosure of the Invention

The objective of the proposed invention is to increase hatchability and increase the safety of young quails by changing the temperature regime and processing hatching eggs.

The technical result that can be achieved with the help of the proposed invention boils down to increasing the hatch and obtaining conditioned young animals and the safety of the livestock in the first 7 days.

The technical result is achieved using a method for incubating quail eggs, which includes treating quail eggs 60 minutes before placing them in the incubator with a 1.5% alcohol solution of propolis tincture at the rate of 150 ml per 1 m ² tray at a temperature of 22°C, after which with 1 -8th day of incubation of eggs in the incubator, the temperature is maintained at -37.7 °C and humidity (RH) 60%, then on the 9th day of incubation, the eggs are re-treated with a 1.5% alcohol solution of propolis tincture at the rate of 150 ml per 1 m ² tray at a temperature of 37.4 ° C, then from the 9-14th day the temperature is 37.4 ° C, RH - 50%, from the 15th day until the appearance of the chicks the temperature is 37.3 ° C, RH - 70%.

Alcohol tincture of propolis contains balms and resins collected by bees from plants. It has a wide range of effects: bactericidal, antiviral, bacteriostatic, anti-inflammatory, analgesic and immunomodulatory. Propolis contains 16 classes of organic compounds and more than 100 biologically active substances. Contains nonessential and essential amino acids, micro- and macroelements.

Carrying out the invention

The method of incubating quail eggs is carried out as follows.

The experiment was carried out in the scientific and educational vivarium of the basic department of private zootechnics, selection and breeding of animals of the biotechnological faculty of the Federal State Budgetary Educational Institution of Higher Education "Stavropol State Agrarian University".

Propolis tincture is prepared from propolis collected from beehives from bees in the period from May to August, then crushed to small granules 1-2 mm in size, placed in a glass container with a lid, filled with ethyl alcohol 96° strength, stirred with a glass rod for 5-6 min, and removed to a place without exposure to direct sunlight for 7 days, components are added in the following ratio, wt.%:

Propolis 10.0 Ethanol 90.0

To obtain 1.5% alcohol tincture of propolis, take the prepared concentrated propolis tincture, place it in a glass flask with a lid, then add distilled water and stir with a glass rod for 2-3 minutes, in the following ratio, wt.%:

Propolis tincture concentrated 1.5 Distilled water Rest

An experimental group of 80 eggs was formed from the parent flock of quails of the Texas population, which were treated 60 minutes before being placed in the incubator with a 1.5% alcohol solution of propolis tincture at the rate of 150 ml per ¹ m2 of tray at a temperature of 22°C. From the 1st to 8th day of egg incubation, the temperature in the incubator is maintained at 37.7°C and humidity (RH) 60%.

Then, on the 9th day of incubation, the eggs are re-treated with a 1.5% alcohol solution of propolis tincture at the rate of 150 ml per 1 m ² tray at a temperature of 37.4 ° C. Subsequently, from days 9-14, the temperature was 37.4 ° C, RH - 50%

From 15 days until the chicks appear, the temperature is 37.3°C, RH - 70%. The proposed incubation mode for quail eggs is shown in Fig. 1.

When using the claimed method, the waste of eggs with embryos that died at the last stage of development is significantly reduced, resulting in an increase in hatchability by 4%, and the hatchability of quails by 5%. The use of a differentiated egg incubation regime in combination with pre-incubation treatment with a 1.5% alcohol solution of propolis tincture can significantly increase the hatch of standard day-old young quails and reduce the amount of incubation waste to a minimum.

The industrial applicability of the method lies in the fact that it is efficient and can be used at breeding poultry farms and hatcheries.

The developed method of incubating quail eggs has a beneficial effect on the development of embryos. The result is a 4% increase in hatchability and a 5% increase in chick hatching compared to traditional incubation. In fig. Table 2 shows the actual results of incubating quail eggs in the traditional and new way.
