Use of Horse Wormers

This can be done in several ways.

Interval dosing means using a horse wormer at regular intervals throughout the year. This can be expensive and sometimes leads to overuse of horse wormers when not strictly necessary. Also the seemingly excessive complexity of regimes used by some establishments makes a potentially complicated disease control programme absolutely beyond comprehension!

Strategic dosing involves the use of specific horse wormers at specific times of year in order to break the seasonal cycle of the parasites. This can be problematic if seasonal conditions change and alter the worm burden and also if heavily infected horses are added to the group.

Targeted dosing is the use of horse wormers only when parasite levels (measured by faecal egg counts or blood ELISA) dictate this to be necessary. Unfortunately the larval stages of the cyathostomes for example dont often show high faecal levels so this can be problematic.

The Links Veterinary Group can advise on the best horse worming strategy for your horse. One of the most common methods used is a combination of interval dosing and strategic dosing whereby twice yearly tapeworm treatment is combined with a broad spectrum wormer (which shows activity against mucosal cyathostome larvae) every three months.
