The practice of successful poultry farms shows that the prevention of poultry parasitoses includes a complex of therapeutic and prophylactic measures aimed both against exogenous oocysts in the environment and against endogenous stages of thepathogen inside the bird's body with the use of modern antiparasitic drugs. In view of the foregoing and special resistance of Eimeria oocysts in the environment, it is possible to create an effective disinfectant against them using several active ingredients and excipients. Among these drugs, we should note glutaraldehyde, crystalline iodine and potassium iodide when used together at optimal concentrations.The experiments were carried out from August to October 2019 in the laboratory and vivarium of the Institute on 60 14-day-old Cobb-500 broiler chickens. Working solutions of Cystodez-ultra in different concentrations were prepared in advance, as well as a buffer solution WSH for preserving bird feces. Cystodez-ultra is a complex drug in a liquid form for disinfection of veterinary supervision objects and prevention of invasive diseases of birds. In the test, the chickens of the first, second and third groups were administered 1 ml of a suspension of Eimeria spp. oocysts treated with 3, 4 and 5% solutions of Cystodez-ultra orally using a micropipette; the fourth group was also administered 1 ml of a suspension of Eimeria oocysts treated with Phenol solution 4%. Broilers of the fifth group were administered a suspension with sporulated Eimeria spp. oocysts at a dose of 2000 per 1 ml not treated with a disinfectant - the infected control, and the sixth group 1 ml of WSH buffer solution - non-infected control. During the experiment, the chickens were followed up daily paying attention to their general condition, behavior, appetite, and visible physiological changes. According to the study results, the intense-effectiveness of Cystodez-ultra in 3, 4 and 5% concentration against sporulated Eimeria oocysts was 93.08, 100 and 100%, respectively, and Phenol in 4% concentration 76.92%. The number of oocysts in 1g of feces in the infected control was 4680 specimens, and the chickens of the uninfected control remained free from the invasion at all times of the study.
