Method of incubating eggs poultry

 

(57) Abstract:

Usage: agriculture, namely incubation of eggs of poultry. The inventive eggs medium and large mass lay with an interval of 4 h at a temperature mode: 1 to 4 days - 30,0 - 38,3oWith, from 5 to 13 days - 37,5 - 37,6oWith, from 14 to 19 day - 37,2 - 37,3oC, and the sample start over 510 hours from the moment of laying eggs average weight. The application of the proposed method of incubating eggs can improve the hatchability of 1.7 - 2.5%, and the safety of the birds 1.9 - 2.2%. table 1.

The invention relates to agriculture, namely, to the incubation of chicken eggs large and medium weight.

It is known that for calibrated by weight of duck eggs in the first 24 h of incubation creates increased to different levels of temperature (37,8 to 39.5about(A. C. UNHIP N 1727757).

In common with the claimed invention is the calibration of eggs and the use of higher temperatures during the incubation of eggs in large masses.

However, the applied method to incubation in three different cabinets for eggs of different weight categories, for which there is a need for the accumulation of such eggs, in order to fill the wardrobes of the incubator. € The threat of overheating of eggs and destruction of embryos.

Known developed differential in temperature and humidity mode, used for egg mass 50-57 and 58-67 g (Bulletin of the research Institute of breeding and genetics of C. farm animals, 1988, 108 N, S. 36-38).

However, here the mass of eggs is limited 50-67 g, the duration of egg incubation mass 58-67 g for 2 h more, and used reusable reconfiguration mode incubation requires an increase in labor costs.

It is known that the currently used mode of incubation chickens, described in "guidelines for incubation of eggs C.-H. birds" (1991). When one party in a Cabinet incubator incubated eggs of small, medium and large mass with a phased bookmark them 6 hours between calibers and at a constant temperature of 37.6aboutAnd the humidity 50-56% in the incubation periods. A sample of Chicks produced after 512 hours from the moment of laying eggs average weight.

This solution is chosen as a prototype.

In common with the claimed invention is a method of calibrating the egg mass with subsequent gradual tab for incubation. But used mode does not provide the claimed technical result. This is due to the following:

with this technology incubation hatched juveniles significantly the Oh mass takes place with varying intensity due to different speed warm-up eggs at the beginning of incubation;

in the second half of incubation, when the eggs begin to distinguish biological heat, there is a danger of overheating of the embryo.

The basis of the invention the task is to get large even-aged young for growing large meat chickens.

The technical result consists in increasing the hatchability of eggs, increase the quality of the Chicks and their safety when growing and also save energy.

The inventive method consists in the following.

Eggs medium, and large masses lay on incubation with an interval of 4 h at a temperature mode: 1 to 4 day 38,0-38,3aboutFrom 5 to 13 days of 37.5-37,6aboutWith, from 14 to 19 days 37,2-37,3aboutSince, moreover, the sample start over 510 hours from the moment of laying eggs average weight.

Specific example on Perm broiler poultry and experimental farm breeding.

Selected the same number of eggs, meat chickens for experimental and control groups. Experimental groups were incubated in the incubation period on the proposed method and the conventional control mode.

In the experience of eggs large mass (66-73 g) number 5648 pieces laid on incubation in 20 h, and egg average weight (58-65 temperature value 38,0-38,3aboutFrom 5 to 13 days of 37.5-37,6aboutWith 14-19 days 37,2-37,3aboutWith moisture 50-56%

In the control group eggs large mass in the number 4620 piece was put in an incubator at 18 h, and egg average weight in the number 9254 PCs in 24 hours. During the incubation period was maintained with 1 18.5 night temperature 37,60,1aboutWith moisture 50-56%

The sample in the experimental group was started 6 h, and in control at 8 h in the morning, first Chicks hatched from eggs of average weight, and then from eggs in large masses.

Incubation results in the table.

The data show that the proposed technology incubation of chicken eggs large and average weight has improved the hatchability of eggs of 1.7 to 2.5% and the safety of the birds 1.9-2.2%, and because the incubation period is reduced by 2-4 hours, then reduced electricity costs.

METHOD of INCUBATING EGGS POULTRY, including the calibration of the egg mass with subsequent gradual tab in the incubator with humidity of 50 to 56% and the corresponding temperature regime, characterized in that the eggs are medium and large mass lay with an interval of 4 h and incubated at the temperature: 1 to 4 day 38,0 - 38,3oFrom 5 to 13 days of 37.5 - 37,6oWith, from 14 to 19
