Effect of the Biosapin probiotic and the biolide disinfectant on the microclimate of poultry houses

Currently, in the field of poultry farming, the issue of using disinfectants for surface treatment of poultry houses, incubators and hatching eggs is particularly acute. Preparations must be both effective for the destruction of pathogenic microorganisms resistant to antibacterial substances, and safe for the environment, productive poultry and poultry goods. The purpose of this study was to test the Biosapin probiotic and the Biolide disinfectant in industrial conditions of a poultry house and incubator room. These preparations were used by aerosol spraying in the incubator and output cabinet, as well as in the poultry house in the presence of poultry. They were tested both individually and in combination, compared to the control group, where no preparations were used. The parameters of the microclimate of the premises were determined: temperature – with a weekly thermograph M-21, relative humidity – with an Augusta psychrometer and hygrograph M-16, speed of air movement – with an ASO-13 vane anemometer, illumination – with a luxmeter, concentration of carbon dioxide, ammonia, hydrogen sulphide – using gas analyser UG-2, dust pollution – according to weight method, microbial pollution – according to sedimentation method. For the first time, a production test of the use of the Biosapin probiotic and the Biolide preparation in the complex was carried out. The obtained research results indicate an improvement in the microclimate of poultry houses. It was found that when spraying a disinfectant, microbial contamination in poultry premises decreases by 48.1% (P<0.001), and when spraying a probiotic – by 62.4% (P<0.001), while with a complex alternating action of both drugs – by 84.1% (P<0.01). At the same time, the bird's body is sanitised and enriched with probiotics. The positive effect of drugs on the microclimate in both the incubator room and the output hall sections has been experimentally confirmed. In particular, the concentration of ammonia decreases by 7.6% (P<0.01), 12.3, 27.8% (P<0.001) and hydrogen sulphide – by 16.6% (P<0.001), 18.5 and 34% (P<0.001). At the same time, the carbon dioxide content also decreases by 2.8, 3.3, and 5.0 times, respectively. Spraying the Biosapin probiotic and the Biolide disinfectant both separately and in combination stimulate embryogenesis, contribute to the production of more fertilised hatching eggs and the hatching of conditioned young chickens. Thus, the breeding rate of young animals increased by 5.5% (P<0.01), by 7.0% (P<0.01) and by 11.0% (P<0.01). The use of the preparations under study lies in the optimisation of the microclimate in poultry premises through such indicators as relative humidity, concentration of harmful gases (ammonia, hydrogen sulphide, carbon dioxide), dust, and microbial air pollution
