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.
在提交给乌得勒支兽医学院家畜内科的3791匹马和小马中，对粪便进行了寄生虫检查。结果按年龄组和到达月份进行分类。发现圆线虫属虫卵存在于57.3%的粪便样本中，马副蛔虫卵存在于6.1%的样本中，马尖尾线虫卵存在于1.2%的样本中，安氏网尾线虫卵或幼虫存在于0.2%的样本中，裸头绦虫卵存在于2.5%的样本中，鲁氏艾美耳球虫卵囊存在于0.3%的样本中。发现六周龄以下马驹的粪便样本中，有56.4%含有韦氏类圆线虫卵，而6至12月龄马驹的这一比例为12.3%。在12月龄以上马和小马（3340匹）的粪便样本中，观察到肝片吸虫卵的占0.6%。8月份记录到含有圆线虫属虫卵的粪便样本比例最高（65.2%），而4月和10月这一比例分别为52.4%和50.7%。10岁以上的马和小马未观察到马尖尾线虫卵、安氏网尾线虫卵或幼虫以及鲁氏艾美耳球虫卵囊。另一方面，在15岁以下的动物中仍发现有马副蛔虫卵。
