Abstract. Modern technologies for the production of livestock products provide for long-term keeping of young animals indoors with an artificial microclimate. That is, it is expected to maintain within the required limits of temperature, humidity, gassiness, lighting level, etc. In particular, to compensate for solar radiation, ultraviolet irradiation units are used.
The main criterion of UV irradiation is the dose, which is individual for each species and age of animals. The obtained amount of irradiation depends on the type and power of the radiation source, the height of the suspension, the continuance of the irradiation process. Therefore, existing mobile UV irradiators need to be upgraded for efficient operation.
The purpose of the study is to develop a UV irradiation system for a room with pigs of different ages and weights in pens with the possibility of automatically providing the required dose.
In order to increase the accuracy maintenance of the recommended dose of UV radiation, the authors use a video camera and a device with software that fulfils the effect of "pattern recognition" and automatic control of the installation during its movement over animals, which are kept in boxes in different age groups.
Experimental studies showed that in the experimental groups of pigs, where irradiation was carried out using the developed unit of automatic control of the UV installation, the set of live weight in piglets was 20-25 % more than in the control group.
Key words: ultraviolet radiation, irradiation installations, erythema radiation, light microclimate, young animals
