CYSTODES-ULTRA AGAINST OOCYSTE EIMERIA SPP. BROILER CHICKEN

The practice of successful poultry farms shows that the prevention of poultry parasitosis includes a complex of therapeutic and prophylactic measures aimed both against exogenous oocysts in the external environment and against the endogenous stages of the pathogen inside the bird's body, using modern antiparasitic agents. Taking into account the noted and special resistance of eimeria oocysts in the external environment, it is possible to create an effective disinfestation agent against them using several active ingredients and excipients. Among these drugs, glutaraldehyde and crystalline iodine should be noted, 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 14-day-old Cobb-500 60 broiler chickens. Cystodes-ultra working solutions in different concentrations were prepared in advance, as well as a buffer solution WSH, a means for preserving bird feces. Cystodesis-ultra is a complex agent in the form of a liquid for disinfection of objects of veterinary veterinary supervision and prevention of invasive bird diseases. When testing the chickens of the first, second and third groups were given 1 ml of a suspension of Eimeria spp. oocysts, treated with 3; 4 and 5% solutions of Cystodes-ultra, inside using a micropipette; the fourth also 1 ml of a suspension of eimeria oocysts, treated with a 4% phenol solution. Broilers of the fifth group were given a suspension with sporulated Eimeria spp. oocysts at a dose of 2000 per 1 ml, untreated with a disinfectant the infected control, and the sixth group 1 ml each of WSH buffer solution non-infected control. During the experiment, the chickens were monitored daily, paying attention to their general condition, behavior, appetite, and visible physiological changes. According to the research results, the intensity of Cystodesisultra 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 1 g of litter in the infected control group was 4680, and the chickens of the uninfected control remained free from invasion at all times of the study.
