AbstractCoproscopic examinations of European roe deer (Capreolus capreolus) were conducted in September and October 2012 in the Zlotowek Forest Inspectorate (Lower Silesia). Rectal faecal samples were collected from 41 animals after planned hunting carried out in the Forestry, and were examined using Wilis-Shlaaf’s flotation, McMaster and Baermann method. Gastrointestinal, bronchopulmonary helminths and coccidia (Eimeria) were found in 39 out of 41 investigated fecal samples (95%). The greatest extent of infection was observed for gastrointestinal nematodes of the family Trichostrongylidae – 95%, with the average number of eggs in a single fecal sample being 94. The presence of a few nematode eggs from Trichuris spp. (22%) and Nematodirus spp. (9.7%) types was also noted. Larvae of Dictyocaulus viviparus lungworms were found in 17% of the fecal samples, numbering from 2 to 25 (average 6) per sample. Oocysts of coccidia of the genus Eimeria were present in 27% of stools, with an average number of 18 in a single sample. According to the scientific data, a massive invasion of gastrointestinal parasites, especially nematodes, is having an impact on the size of the cervidae population, including roe deer. The negative effects of the parasites are manifested in disorders of reproduction, inhibition of growth of juveniles, reduced immunity and animal health, as well as lowering the quality of carcasses and antlers. Roe deer parasites are also a potential source of invasion for domestic ruminants. The population of roe deer has steadily increased in recent years, and the fields and meadows are their living space as well as its food base, leading to pollution of the environment with dispersive forms of parasites, including gastrointestinal roundworms. Hence this constitutes a real risk for animals, especially those kept in the grazing system. Based on the results obtained from the coproscopic examinations, it seems reasonable to continue the systematic parasitological monitoring of free-living wild animals. This will not only assess the efficacy of prophylactic measures, but it will also help to develop and implement a comprehensive program to improve the health of the roe deer population.
