Abstract
Microbial contamination in agricultural environments poses a significant challenge, impacting both animal health and overall biosecurity.The study conducted at "Aidarbaev E.S." and "Agrofarm Dinara" revealed a significant accumulation of microorganisms on floors and walls, with concentrations ranging from 32.4 x 10 3 to 45.6 x 10 3 , while microbial counts were comparatively lower at drinking bowls.The application of a hydrogen peroxide-based disinfectant in the wet method demonstrated an average disinfection efficiency of 79.3%, surpassing other tested agents.Furthermore, the foam method using the same hydrogen peroxide-based composition exhibited a higher efficiency of 86.2%, highlighting its superiority over wet disinfection by 6.9%.Additionally, the iodine-based disinfectant composition, at a concentration of 0.5%, demonstrated a substantial impact on poultry houses and barns, reducing microorganism counts by 72.1% to 76.5% after a 3-hour exposure.Importantly, this disinfection process had no adverse effects on the physiological and clinical status of animals and birds, with hematological and biochemical indicators suggesting an improvement in the immune system by 9.2% in birds and 16.8% in dairy cows.Overall, our findings emphasize the effectiveness and safety of hydrogen peroxide and iodine-based disinfectants in enhancing biosecurity and animal health in agricultural settings.
