A ‘one size fits all’ solution can never be ideal. We need to manage the worm burden in every horse differently because they are individuals and every situation is unique. It is also important for us to use wormers responsibly. If we use wormers too frequently or unnecessarily, we could eventually reduce their effectiveness in controlling parasites (known as resistance). This is why the experts advocate more sustainable worm control, using a targeted approach to tackle a specific worm burden at any given point, rather than the old-fashioned ‘catch all’ method of routine worming every horse every 6-13 weeks.
Manage the worm challenge on the pasture
Reducing the number of worms on the pasture will help to keep the re-infection challenge to a minimum. This in turn reduces our reliance on wormers, slowing the drive for wormer resistance.
Test the worm burden
Regular faecal worm egg counts play a major role in allowing you to target your worming treatment effectively. They can also be used to check that your existing worming programme is working.
Plan your worm control programme
A thorough history of your horse’s health and worming regime, together with an assessment of his living environment and field companions, will help you to build the best possible worming programme.
Dose with the right active
When you have identified that a wormer is needed you should always select the one most appropriate for the parasite you are targeting. You must also make sure you treat your horse accurately according to weight. This will help to maintain the effectiveness of the wormers currently available to us.
