title: [Studying the faeces for the presence of parasites in horses and ponies (author's transl)].
abstract: In 3,791 horses and ponies submitted to the Department of Internal Disease of Farm Animals of the Faculty of Veterinary Medicine, Utrecht, the faeces were studied for the presence of parasites. The results were classified by age groups and months of arrival. Eggs of the Strongylus type were found to be present in 57.3 per cent of the faecal samples, eggs of Parascaris equorum were present in 6.1 per cent, eggs of Oxyuris equi in 1.2 per cent, eggs or larvae of Dictyocaulus arnfieldi in 0.2 per cent, eggs of Anoplocephala in 2.5 per cent and oocysts of Eimeria leuckarti in 0.3 per cent. Eggs of Strongyloides westeri were found to be present in 56.4 per cent of the foals under six months and in 12.3 per cent of those in the 6-12 month range. Eggs of Fasciola hepatica were observed in 0.6 per cent of the faecal samples of horses and ponies over twelve months of age (3,340). The highest proportion of faecal samples containing eggs of the Strongylus type was recorded in Augusts (65.2 per cent), whereas this proportion was 52.4 and 50.7 per cent respectively in April and October. Eggs of O. equi, eggs or larvae of D. arnfieldi and oocysts of E. leucarkti were not observed in horses and ponies over ten years of age. On the other hand, eggs of P. equorum were still found to be present in animals up to fifteen years of age.
