EFFECT OF RADIATION BY ULTRAVIOLET AMALHAM LAMPS ON THE NUMBER OF LITTER MITES

Abstract

Mites of the genus Tyrophagus are found everywhere, including in poultry farms. These mites are not parasites of chickens, but they cause indirect effects on chickens in the form of digestive disorders. The main part of the mites dies during the disinvasion of the house in a preventive break. But mites can be brought into the house with biological substrates later. Therefore, it is necessary to look for methods to destroy these mites. The aim of our work was to study the effect of ultraviolet radiation of amalgam lamps with high bactericidal power on the number of adult mites of the genus Tyrophagus in the litter when growing broiler chickens in the experiment. We take broiler chickens, which were divided into two groups, 200 heads each. Broiler chickens were placed in two boxes: experimental and control. Illumination was carried out using LED lamps in both boxes. In addition, UV radiation was performed using an amalgam lamp with a bactericidal radiation power of 90 W in the experimental one. After the birds were planted for research, from 7-day-old chickens to slaughter, every 7 to 8 days, 10 litter samples were taken from both boxes. The research results showed that the extensiveness and intensity of adult ticks of the genus Tyrophagus in the litter from an experimental box is much less than from the control box. Thus, when the surface flux density of UV radiation is 7–11 mW/m2, the number of mites in the litter decreases.
