STUDY OF THE PREVALENCE AND METHODS OF DETECTION OF EIMERIOSIS AMONG RABBITS DEPENDING ON DIFFERENT METHODS OF KEEPING

Abstract

One of the key difficulties in the process of raising rabbits is eimeriosis, regardless of the methods of keeping them. This disease affects animals of all age groups, leading to a decrease in weight gain, deterioration of the efficiency of assimilation of feed, increased morbidity. The purpose of the study was to determine the prevalence and methods of detection of eimeriosis among rabbits, depending on different methods of keeping, with the aim of improving strategies for combating this disease and improving quarantine methods. During the period from 2019 to 2021, research was conducted in farms with different power levels in four regions: Zaporizhzhya, Donetsk, Kharkiv and Sumy. In total, 20 farms where rabbits of different breeds were kept were surveyed. In farms and private rabbit farms, E. intestinalis, E. magna, E. media, E. piriforms, E. perforans, E. irresidua were isolated. It was proved that in the winter period the level of oocysts was from 12±1.2 to 34±2.4 in p.z. microscope In the summer period, the level of infestation decreased and ranged from a maximum of 15±1.2 (EI = 19%) to a minimum of 5±2.0 (EI = 6%). The study confirmed that in conditions of keeping in metal cages in farms, with compliance with sanitary and hygienic norms and regular disinfection of premises, the level of infestation was from 15% to 42% in the winter period and from 6% to 19% in the summer period. In an analysis of data obtained from private farms where rabbits are kept in wooden cages with deep bedding, it was found that the infestation rate was between 56% and 100% during the cold period and between 29% and 70% during the warm period. The use of metal cages for keeping rabbits in compliance with sanitary and hygienic requirements and timely disinfection helps to reduce the prevalence of parasitic infections.
