DEWORMING of horses is an integral part of basic equine husbandry, but the advice for deworming horses has changed dramatically in the last number of years.

The old practice of deworming all horses at regular intervals, the frequency being determined by the active ingredient in the wormer product used, is now defunct! We have learned that this protocol, faithfully followed for years and performed with the best of intentions, unnecessarily ‘over-wormed’ the majority of horses.
