Who, when and how often?
The information is based on the recommendations of the Vetsuisse Faculty.
Young horses (up to the 4th grazing period)
Young horses are “traditionally” dewormed, i.e. 3 to 4 times a year. A subsequent examination of dung after deworming makes absolute sense. Thus it can be checked whether the deworming has worked or whether resistance is already present.
Adult horses (from the 4th grazing period onwards)
Adult horses are checked as follows:
- In the first year: 4 examinations, in May, July, September and November.
- In the following years: 2 examinations suffice, e.g. in May and October, if the examinations in the previous year have given no cause for deworming.
- Irrespective of the results of the dung analysis, in order to be safe, all horses must be dewormed with a broad-spectrum dewormer before the winter. Your vet will be pleased to help you further with the choice of medication.
- A resistance check and larvae culture for differentiating between large and small strongyloides should be undertaken at regular intervals at herd level.
