The gaining of maximum amount of daily young animals in a greater extent depends on disinfection of incubation eggs which in complex of veterinarysanitary arrangements held in poultry factories on prevention and elimination of poultry infectious diseases takes an important part. The perspective of ozone application in industrial poultry breeding is conditioned with its advantages which it characterizes in comparison with other chemical substances. It was settled that ozone has a special ability to detain the growth of fungi on biological substrates, also the process of mould appearance on the surface of eggs’ shell even at 90% of relative moisture. At substantiation of parameters and regimes of electro-technological process of egg storehouse ozonation there were implemented the experimental researches. The general bacterial semination of eggs’ shell decreased on 94,1% after disinfection of incubaion eggs with ozone. The relative faults of experimental values from theoretical ones are 7%. In the result of production trials there were set the parameters of quality of the worked out electrotechnological process of egg poultry factory storehouse ozonation: time of regulation ‒ 8 minutes, dynamic fault ‒ 0,9, coefficient of overcorrection ‒ 4,5%, generalized integral mean-square index ‒ 10,6%. Obtained data testify against the qualitative regulation of allocation of concentration of ozone in a egg storehouse

In the article, there were shown the experimental researches describing the influence of parameters of electrical ozonization of the premises of egg storehouse at concentration of ozone in 20 mg/m3 on survival of following stimulants: S. aureus, S. choleraesuis, P. vulgaris, E. coli. There was determined that ozone has an ability to detain the growth of fungi on biological substrates as well as it slows down the process of mould appearance on egg shell surface even at 90% of relative moisture. The aim of scientific experiment is obtaining of regression models of influence of parameters of electrical ozonization on main sanitary-model microorganisms contaminating the shell of incubation eggs. To assess the effectiveness of ozonization there was adopted the parameter of survival for four main pathogenic microbiological test-objects which predominate on egg shells. The correlation and regression analysis of factors and determination of value of equation coefficients there were conducted using the program STATISTICA 6.1. The correlation analysis was made by the method of Pierson. Approximation was obtained by the method of polynomial. On the results of researches there was determined that the least survival of present test-bacteria at concentration of ozone in 20 mg/m3 is achieved at exposition 84 minutes. So, the rational time the electrical technological process of ozonization of egg storehouse of poultry factories presents the sum of obtained exposition and time of regulation

Getting the maximum number of day-old chicks largely depends on the disinfection of hatching eggs. Disinfection of eggs is important in the complex of veterinary-sanitation activities carried out in poultry farms for the prevention and elimination of infectious disease in birds. The perspective of using ozone in the poultry industry is possible due to its advantages characterized in comparison with other chemicals. It was found that ozone has the special ability to retard the growth of fungi in the biological substrates, also slows the appearance of mold on the surface of the eggshell even at 90 % relative humidity. When making parameters and modes of electro-ozonation process of egg store poultry farms there were carried out experimental studies. After ozone disinfection of hatching eggs, total bacterial contamination of shell eggs decreased by 99.89 %. The relative error of the experimental values of the theoretical amount was 7 %. As a result of production tests we set quality parameters developed by the process of electroozonation egg store poultry farms: regulation time is 8 minutes, dynamic error is 0.9, overshoot rate is 4.5%, generalized integral RMS figure is 10.6 % . The findings suggest that there is a qualitative regulation of the distribution of ozone in the egg store

Ozonization of incubation eggs when storing at an egg-storehouse is well included in technological process of production and egg sorting. Ozone influences absolutely all known viruses and microbes. Larger chickens are hatched from ozone-treated eggs, safety of chickens is increased. However, the present technology did not obtain the wide spreading in the sphere of poultry farming because of uneven concentration due to the volume of treated premises. In the result of mathematical modeling there was worked out the system of management with electrical and technological process of ozonization of egg-storehouses of poultry factories, indexes of quality the work of which was assessed in the system of automated projecting of logical-dynamic systems SimInTech. The summarized integral mean-square index (J = 9,7%) decreased on 19,3 % in comparison with the variant without regulation (J = 29%), that testifies on enough qualitative regulation of distribution of ozone concentration in an egg-storehouse and satisfies the shown acceptable value of the present index (no more 15%). On the basis of produced researches there was created the nomogram determining the tension of charging facility and discharge of a ventilator of electric ozonator in dependence on treated egg amount. In accordance with technical solutions there was worked out the principal electric circuit with system of electric equipment of electric technological process of ozonization of egg-storehouses of poultry factories on the basis of microcontroller ATmega8

Sanitization of eggs is an essential way to fight bacteria, fungi and other microorganisms. Hatchability of eggs and the safety of day-old chicks are dependent on the quality of eggs processing. Leading scientists of our country have proved high efficacy of ozone application for processing of hatching eggs. To obtain a positive result by this method of sanitizing hatching eggs ozone, it is necessary to create a uniform concentration of ozone around the egg store volume. Decrease in ozone concentration from the set point may result in insufficient exposure to pathogens and because of this, may reduce hatchability. Significant excess of ozone concentration from the set point can kill the embryo. Because of mathematical modeling of electro eggs ozone treatment process, there was a mathematical model of the process of electroozonation of egg stores of poultry farms. This model takes into account decomposition of ozone on the surface of eggs and decomposition of ozone on the walls of an egg store. This mathematical model proves the desired control action at different initial data, such as: the required concentration of ozone in the egg store, the number of eggs, egg store geometric dimensions, the fan power, the design parameters of the discharge unit, the location of the ozone generator in the room
