Duynov E. The improvement of regimes of air disinfection in poultry house at the presence of birds when breeding broilers

On the base of investigations of microbe contamination of poultry houses under the up-today industry technology of broiler raising and different density of birds placing, the influence of microbe contamination of air on the safety and live weight of birds it has been grounded the necessity of periodic carrying out of air treatment in poultry houses at the presence of birds with the aim of decreasing air microbe contamination from the 20 to the 25-th day of broiler breeding. It has been suggested to carry out such treatment by the aerosol method or with the use of ultra-violet radiation; the experimental regimes of conducting the treatment of air by the both methods have been worked out. On the base of investigations the choice of the preparation for aerosol method of air treatment has been made. It has been studied the effect of proposed methods and worked out regimes of air treatment at the presence of birds on the microflora of poultry houses, indices of broiler breeding, biochemical indices of blood, meat output, development of internal organs. The use of the proposed regime of air contamination by the aerosol method allows to reduce the air contamination in 1,6-3,2 times, to increase the safety of birds by 1,8%, the live weight of birds at the age 42 days on 35.03g. The use of the proposed regime of air contamination by the ultra-violet radiation allows to decrease the air microbe contamination in poultry houses in 2,403,7 times, to increase the safety of birds by 2,2% and to increase the live weight of birds at the age of 42 days on 137g.
