Efficiency of the disinfectant which based on lactic acid during aerosol disinfection in presence of the birds

Abstract

In the industrial production of broiler meat, the productivity and quality of meat are important. To increase their productivity and meat quality, they create optimal housing conditions. It depends on many factors, especially the technology of poultry farming. The main way to maintain the natural resistance of poultry in production conditions – the use of quality and safe disinfectants. Experimental laboratory investigations have found modes of disinfection of poultry air in the presence of broiler chickens, when using a disinfectant “Biolaid” based on hydrogen peroxide, lactic acid and lactic acid. The reduction of microbial indoor air pollution and the increase of poultry productivity have been set up, which has made it possible to get economic efficiency of production. According to the results of research, the optimal regime of aerosol disinfection of poultry houses with the use of 0.2 % disinfectant “Biolaid” – 50 ml/m3 of the room at an exposure of 60 minutes is recommended. Disinfection of the premises in the presence of poultry during the rearing of broilers in the period before planting and processing every 6 days in the period from 6 to 41 days of age reduces the microbial background of indoor air. It was found that before the experiment the total bacterial air pollution in the experimental group was 191.0 ± 12.7 thousand CFU/cm3. After disinfection with Biolaid disinfectant, the bacterial air pollution of the room was 320.0 ± 7.1 CFU/cm3, which is almost 100 % and confirms its effectiveness. It was found that the body weight of chickens at 6 weeks of age increased by 225 g compared to the control group. Aerosol treatment of air is non-toxic and has no negative influence on the physiological state, which is confirmed by researches of morphological indices of poultry blood.
