Production tests disinfectant AKVADEZ-NUK 5

Abstract

Disinfection plays a significant role in the overall complex of antiepizootic measures. In order to provide manufacturers with a high-quality and cost-effective disinfectant in production conditions and in order to determine the optimal disinfection regime, we conducted production tests of the AKVAdez- NUK 5 disinfectant at the veterinary supervision facility for the stable maintenance of cattle in the Kalacheyevsky district of the Voronezh region. During the production tests, the following concentrations of working solutions were studied: 0.1%; 0.25%; 0,5%. The solution was sprayed with a TORNADOSCO/52 foam generator. The consumption rate was determined as 0.35 l/ m2 with an exposure of 30 min. When using 0.1% concentration of the AQUAdez-NUK 5 working solution with an exposure of 30 minutes, growth was recorded in 16 out of 20 samples during the study for E. coli growth. 4 samples taken from concrete surfaces were disinfected. In samples taken from concrete surfaces to determine the growth of S. aureus, the growth of colonies of microorganisms was observed in all flushes. When using 0.25% AQUAdez-NUC 5 solution in the test, in 16 of the 20 flushes selected to determine the growth of E. coli and 14 out of 20 samples on S. aureus, we did not observe the growth of microorganisms. When treating objects of veterinary supervision with 0.5% AQUAdez-NUC 5 solution after 30 minutes of exposure, there was no growth of microorganisms in 100% of the studied samples on both E. coli and S. aureus during crops from flushes from concrete and wooden surfaces. According to the results of disinfection of the surfaces of the livestock premises with respect to E. coli and S. Aureus, the working solution AQUAdez- NUK 5 showed bactericidal activity in 0.5% concentration with a 30-minute exposure at a consumption of 0.35 l/m2
