Abstract

The aim of this study was to expose shedding characteristics of different Eimeria spp cause coccidiosis. For this purpose, 8 groups of 14 days-old 14 birds were infected respectively with 25×103, 50×103, 100×103, 200×103, 350×103, 500×103, 750×103 and 1000×103 Eimeria spp oocysts and 9th group was determined as control. The infection carried out with the inoculum consist of different field based Eimeria spp Following the infection faecal samples were taken and examined by using the modified McMaster method in terms of oocyst density. Proportional density of E. maxima in stool samples determined base on morphological criterions and quantitative densities also calculated by using same proportional density. The data of our study showed that Eimeria spp and E. maxima dropping progress was releated with infection dose to a certain extent and discarded oocyst amount during the period was not have a linear relationship with the infection dose.
