• Aim to keep your worming programme as simple    as possible, that way you will be more inclined to    stick to it.

• Consult your vet for the appropriate programme    for your horse's particular needs.

• Beware of new horses! Worm new horses with a    wormer licensed to control benzimidazole-
   resistant worms, such as a moxidectin-based    wormer. Keep new arrivals stabled for 48 hours    to ensure eggs are passed out of the horse    before being let out to pasture to avoid pasture    contamination.

• Dose your horse accurately according to its    weight. Using a reduced dose results in more    worms surviving leading to pasture    contamination, as well as contributing to the    development of resistance. Weight can be    established by means of a weigh tape or ideally    weigh scales.

• Follow manufacturers' recommended dosing    intervals based on brands' active ingredient, i.e.    moxidectin 13 weeks, ivermectin 8-10 weeks,    pyrantel 4-8 weeks, fenbendazole 6-8 weeks    and mebendazole 6 weeks.

• Treat your horse at least annually against    encysted small redworm, such as with a single    standard dose of moxidectin.

• Periodically, (i.e. annually) monitor your worming    programme by means of a Faecal Worm Egg    Count.

• Worm pregnant mares before and after foaling.

• Treat for tapeworm in the spring and autumn.

• Worm all horses sharing grazing or on the same   yard at the same time with the same product.

• Keep a record of when you worm and what    you use.
