• Resumen

  • A major problem of large-scale rabbit farming is digestive diseases. Relatively few data on parasitic diseases of industrial rabbit populations are available. The aim of the study was to evaluate the seasonaldependent incidence of Eimeria spp. and Passalurus ambiguus infections at large-scale rabbit farms. The survey was carried out between 2018 and 2022 at 29 Hungarian and 2 Slovakian rabbit farms. Altogether, 7612 faecal samples were examined. Eimeria oocysts and P. ambiguus eggs were detected on all rabbit farms examined, although only a relatively small portion of faecal samples was found positive. Eimeria oocysts and P. ambiguus eggs were found in 32 and 6% of the samples, respectively. Our findings for the seasonal-dependent evaluation of collected data showed that the highest proportion of Eimeria positive samples occurred during the summer (35.3%) and autumn (36.2%) periods. In winter, a significantly lower infection rate was found (29.5 %; P<0.05). The most favourable results were observed in spring (25.1%; P<0.05). As for P. ambiguus, the highest rate of infection was measured in spring (8.4%) and the lowest in summer (4.5%; P<0.01). The autumn and winter periods showed intermediate results (6.7 and 5.5 %, respectively).
