Among the different sub-branches of poultry farming, turkey breeding is especially attractive due to the intensive production technology and biological characteristics obtained from turkey products. Based on the experience of turkey farming and analysis of the literature, it is obvious that with the development of industrial turkey breeding, a problem arises associated with the pathology of this species of birds, the study of which has not yet been given due attention. To establish the infestation with intestinal parasitic protozoa of young turkeys in the form of the disease Eimeria spp. in 2020 from a specialized turkey breeding farm of the Penza region of Central Russia, samples of feces were examined for the presence of invasive elements. For research coproscopic methods of Fülleborn and Darling were used. Young turkeys of different ages were examined for eimeriosis by the method of intravital coproscopy. On the farm of the Penza region, turkeys were examined from 7 days of age until the full completion of the technological cycle every 14 days by examining at least 20 fresh samples of feces. The study of the dynamics of the invasion of young turkeys with eimeria in the process of the technological cycle of their rearing showed that the greatest infestation of males fell on 35–49 days of age, EI – 30–45%. In young females, the invasion of eimeria was noticeably lower, the peak of infection was at 35–49–63 days of age, EI – 5–30%. The drug Monensin used by us as a coccidiostatic agent in the recommended dose and scheme provided satisfactory efficacy, preventing the clinical manifestation of coccidiosis in young turkeys during the technological cycle of their rearing. Based on the real epizootic situation at poultry farms, it is necessary to carry out comprehensive therapeutic and prophylactic measures against the noted parasitoses, taking into account the exo- and endogenous stages of parasite development.
