Abstract

A method for stimulating embryonic development of poultry includes putting eggs for incubating, three-time treatment thereof with physical factors, assessing the effect of the physical factors. Selection of fertilized eggs is additionally carried out prior to the treatment by means of candling at the beginning of the prefetal period of embryonic development, low-frequency electric current is used as a physical factor, and assessment of the effect of the physical factors is carried out on completing the incubation.

Description

of the beam, to cause stimulation or inhibition Chicken eggs obtained from one poultry house and embryogenesis, which, in turn, does not carry the necessary laying day were placed in an incubator. On the 9th day of incubation, selection of fertilization was carried out for commercial use in the poultry breeding process. of them eggs, which were divided into control and experimental

The Riemann group problem is the basis of a useful model. The experimental group, in order to develop a method of stimulating the embryonic development, was divided into 3 subgroups. Moreover, the coil of birds, which by means of low-frequency treatment - the first subgroup was treated with a low-frequency electric current three times during incubation - with an electric current with a current frequency of 8Hz of its sition period, starting from the beginning of the tallow current of 12 mA; the second subgroup - with the frequency of the pre-fetal incubation period, increases the output current to 6OHHz, current strength - 60 mA; the third subgroup, the smoke of eggs, reduces the time of incubation and the duration was treated with a low-frequency electric discharge, reduces the mortality of embryos in the process with a current frequency of 124 Hz and a current strength of 330 incubation. ma. As a result of processing eggs with low-frequency electricity

The essential features of the method are: the number of hatched chicks is reduced by the alternating current; decreased by 32,495; the duration of incubation is reduced by 14 hours, and the duration of hatching by 10 hours at the beginning of the pre-fetal period of the embryo; the number of "blood rings" on the nal development decreased; 17,695, and "frozen" and "suffocation" were generally absent - treatment with a low-frequency electric current. eggs from both ends for 60 s three times during the incubation period, starting from the pre-fetal period. Chicken eggs obtained from one poultry house and one incubation period. on the day of demolition, they were placed in an incubator. On

The characteristics that differ from the prototype are: on the 9th day of incubation, a selection of low-fertilization-use as a physical factor was carried out, which were divided into control and expesto electric current instead of low-internment groups. Experimental group, in gray laser radiation; in turn, was divided into 3 subgroups. Processing - assessment of the degree of exposure to low-frequency electric current of experimental eggs was carried out using low-frequency electric current with the help of the analysis of indicators with a constant electric current at a constant frequency of egg hatching, duration of incubation and hatching, bogts and different current strength. As a result of processing eggs, the dynamics of embryo mortality during incubation, and low-frequency electric current, the number of eggs not dissected to estimate the number of hatched chicks increased to 10,095; long-differentiated pairs of somites, which allows the duration of incubation to be reduced by 24 hours and to keep the embryos alive; withdrawal period - for 15 hours; There were no "blood rings", "death due to the use of available methods and techniques" and "suffocation". of the analysis of the degree of influence of low-frequency electric current, unlike the prototype, in which chicken eggs obtained from one poultry house and used to analyze the number of eggs formed on the day of laying were placed in an incubator. Differentiated pairs of somites were selected using a microscope on the 9th day of incubation. of them eggs, which were divided into control and experimental

The method is performed as follows. Realization of the group. The processing of hatching eggs, including the selection and laying of eggs for incubation according to the experimental group, was carried out using low-frequency techniques. Then, the ovoscope is carried out with an electric current with a current frequency of 60 mA at the beginning of the prenatal period, which is boHz. As a result of processing, it is possible to select fertilized eggs. Reflector with a low-frequency electric current, fertilized eggs are treated with a low-frequency, the bone density of hatched chickens increased by 28.6905; electric current from both ends. Processing effects - incubation duration reduced by 16 hours, and sleeps for 60 seconds each time. Incu - duration of withdrawal - for 11 hours; "blood rings" basation eggs are treated three times during incubation. decreased by 18,995, "frozen" and "suffocated"

There were no evaluations after the end of incubation. influence of physical factors.
