Efficiency of complex disinfecting measures in the conditions of poultry farm-ing

The key to successful work of a modern poultry industry and the safety of its products for consumers is high-quality disinfection. Modern disinfectants used in poultry farms are different in composition, concentration of active substances, means of application and other properties. Most of them are represented by imported products. Their replacement in the domestic market with effective, safe and economical drugs is extremely relevant. It should be highly effective means, possessing a wide spectrum of virilicidal, bactericidal, sporocidal and fungicidal action. The goal of the work. The purpose of our research was to evaluate the effectiveness of the complex disinfection in the production conditions of the Bi-Dez and DezSan products. Materials and methods of research. Production testing of the disinfection of poultry facilities and equipment using the Bi-dez and DezSan schemes was carried out at one of the poultry farms of the Sumy region. At the first stage, the water supply system was treated by filling the piping line with a 0.1% solution of Bi-dez with an exposure of 1 hour. At the second stage, moisture was disinfected with 0.8% solution DezSan from the rate of 0.2–0.3 liters of solution per 1 m2, exposure time – 2–3 hours. Then, in the room, the fine dispersed aerosol of this biocide was sprayed into a 10% solution (1 liter of preparation per 9 liters of water) – aerosol disinfection by fogging at a rate of 5 ml of solution per 1 m3 of space, exposure time – at least 3 hours. Results of research and discussion. Evaluating the effectiveness of disinfection of the water supply system with the Bi-dez compound, found that the total microbial contamination of the water before treatment was 235 CFU/ml. In addition to other bacteria, it was isolated from the intestinal bacillus. After the rehabilitation, the microbial water pollution decreased to 4 CFU/ml. Sanitary-indicative microorganisms (E. coli, salmonella and staphylococci) were not detected in the system faults. The total amount of microorganisms in the air after disinfection with the drug DezSan decreased by 2.6 times (12 thousand mc/m3) compared with the baseline bacterial background (29 thousand mc/m3), and the intestinal rod after treatment from the selected in the poultry house air samples were not allocated. Conclusions and prospects for further research. Reducing the microbial background and the death of opportunistic microorganisms in the premises and the system of drinking poultry farms contribute to the veterinary well-being of poultry farms. In the future, it is planned to conduct a study of the drug DezSan, identified it irritating, skin-resorptive, cumulative and other properties.
