Description

The invention relates to the poultry industry, namely the incubation of eggs of poultry. The method includes incubation of chicken eggs, when using eggs with pre-developed embryos.

Known differentiated incubation of chicken eggs, including the laying of eggs of meat cross SK-Rus 6 for incubation. Eggs are incubated at a temperature: from the moment of laying up to 45 hours 37.8-38.0 ° C (if the mass of eggs is more than 65 g), 46-96 hours - 38.5 ° C, 97 hours - 13th day -37, 5-37.6 ° С, from the 14th to the 17th day - 37.2 ° С (if the egg weight is more than 65 g), the temperature is set to 38.5 ° С every 4 hours, after 17 days and before the output it is set temperature 37.1-37.2 ° С (Scherbatov VI, Edygova SB, Cesarskaya EN. Differentiated incubation modes, “Kuban Veterinary Medicine, No. 1, 2012)

Disadvantages:

1. Difficult options for temperature switching in an incubator.

2. A short period of reduction of the incubation period.

A different mode of incubation of chicken eggs is known, including laying eggs by batch, a batch of eggs (52 trays) are placed in three cabinets, 17 trays each. The next 5 batches are laid in a similar way after 3 days. The seventh batch is set in place of the first 4 days after the laying of the sixth, etc. At the same time, 6 batches of uneven-aged embryos will be in the same closet (AA Zabolotnikov, Handbook of the Poultry Farmer, // Edition 3, revised and enlarged - Moscow: Moscow Worker, 1984).

Disadvantages:

1. The method aims to save electricity when creating a temperature regime.

2. It does not allow to synchronize the withdrawal of chickens and shortens the period of embryogenesis.

The technical result of the method is to ensure the reduction of the incubation period of eggs with. -h. birds.

The technical result is achieved by the fact that in the method of incubating chicken eggs, including laying eggs in batches for incubation and changing the temperature in the incubator during the entire incubation cycle, according to the invention, when laying the 1st batch, set the temperature to 39.5 C ° the batch and set the temperature to 37.6 ° C up to the 19th day, from the 20th to the 21st day 37.2 C °, while the eggs of the next batch are laid between the eggs of the previous batch in a checkerboard pattern.

The invention is illustrated in the drawing, where figure 1 shows the laying of eggs.

The claimed technical solution will differ from the prototype in that to ensure the reduction of the incubation period using chicken eggs with pre-developed embryos.

These differences allow us to conclude that the proposed technical solutions according to the criterion of "novelty."

According to the scientific, technical and patent information, the claimed combination of features has not been identified, which allows us to conclude about the inventive step of the proposed technical solution.

Industrial applicability of the method lies in the fact that it can be used for incubating eggs of all kinds with. -h. birds in industrial and breeding poultry farming.

The method of incubation of chicken eggs as follows.

For incubation, the 1st batch of eggs is laid at a temperature of 39.5 ° C, during this period the egg cell is crushed, then after 36 hours the temperature is changed to 37.6 ° C and the next batch of eggs is laid, which is laid between the eggs of the previous batch in a staggered manner . Figure 1 shows the laying of eggs, under position 1 shows the eggs of the 1st batch, and under position 2 - eggs of the next batch. The laying of eggs of the next batch after 36 hours at 37.6 ° C is due to the fact that in the previous batch with pre-developed embryos, the heartbeat begins from the 2nd day of incubation or after 36 hours.

The heartbeat of the chicken embryo begins on the 2nd day of incubation, or rather, from 36-44 hours. The heart is the first organ of the embryo that begins to function, and even before its morphogenesis is completed. It should be noted surprisingly early functional maturity of the embryonic heart.

According to Yankovskaya (1949), the stage of pulsation of the endothelial tube from day 2, when neuromuscular elements have not yet been completely formed in the embryo as a whole and in the heart in particular. At this stage, heart pulsation depends mainly on physical (temperature and fluid pressure in the endothelial tube) and chemical (ion-salt) environmental conditions. The exogenous effect on the heart at the beginning of this stage causes the rapid development of the embryo.

The temperature of 37.6 ° C is kept for up to 19 days, and from the 20th to the 21st day the temperature is set at 37.2 ° C. The embryo emits a lot of energy before the output, so when the output sets the temperature is comfortable for him, if during this period there is a large temperature, then the output will have a large number of suffocation.

The mode of incubation of chicken eggs is presented in table. one

An example of a specific implementation of the method.

To implement the method was selected 200 eggs of chickens meat breeds. The first 100 eggs were laid in the incubator at a temperature of 39.5 ° C, after 36 hours another 100 eggs were planted and the temperature was set at 37.6 ° C until the 19th day, from the 20th to the 21st day 37.2 ° C while the eggs of the next batch are stacked between the eggs of the previous batch in a checkerboard pattern.

The eggs that were laid for incubation initially stimulated the development of eggs that were planted in the incubator after 36 hours. The embryos of the experimental group after 36 hours of incubation of control eggs became equal in development with embryos at the beginning of incubation.

Data on the withdrawal of chickens are presented in Table. 2

Table 2 shows the output of chickens when using the new incubation mode. In the proposed method in the experimental group, the withdrawal of chickens began at 456 hours and ended at 517 hours, and in the control started at 19 hours later, but ended earlier at 6 hours. The output of chickens in the experiment was 70%, and in the control by 10% more (80%).

Thus, when using eggs with pre-developed embryos, planted eggs after 36 hours, a rapid periodicity of embryo development is imposed.

Claims (1)

The method of incubating chicken eggs, including laying eggs in batches for incubation and temperature change in the incubator during the entire incubation cycle, characterized in that when laying the 1st batch, set the temperature to 39.5 ° C, put the next batch after 36 hours and set the temperature to 37 , 6 ° С up to the 19th day, from the 20th to the 21st day - 37.2 ° С, while the eggs of the next batch are laid between the eggs of the previous batch in a checkerboard pattern.
