[Spectrum of species and incidence of endoparasites in foals and their mother mares from breeding farms with and without anthelmintic prophylaxis in upper Bavaria].
In this epidemiological study 37 foals and mares were included, which have been coproscopically examined in regular intervals over a period lasting up to 13 months. The animals derived from nine breeding farms. In three of these farms no anthelmintics were used before this investigation, whereas in six farms at least three years before regular prophylactic treatments with anthelmintics have been carried out. This investigation revealed no differences in the species spectrum of endoparasites as well as in the incidence of infections as regards to the breeding farms with and without anthelmintic prophylaxis, however, significant differences between foals and mares. At least nine species were established in foals, Strongyloides westeri in 54.1% of the animals, Parascaris equorum in 64.9%, small strongyles, whose third stage larvae showed either eight or 12 intestinal cells, in 83.8%, Anoplocephala perfoliata in 16.2%, Eimeria leuckarti in 64.9%, Giardia in 5.4%, Cryptosporidium parvum in 2.7% and Gasterophilus intestinalis in 21.6%. Parasitic infections with two or more species were found in 83.8% of the foals. The species spectrum of endoparasites in mares from breeding farms without anthelmintic prophylaxis consisted of at least three species of small strongyles, whose third stage larvae were characterized by eight, 12 or 16 intestinal cells. In mares from breeding farms practising regular anthelmintic prophylaxis, however, at least seven species were ascertained, the same small strongyles, P. equorum, A. perfoliata, E. leuckarti and G. intestinalis.
