Effective worm control

We need to break reliance on wormers as the treatment of choice for worm control and learn to deal with acceptable parasite burdens rather than aiming for parasite-free horses.


This can be achieved by:


1. Effective pasture management

· Removal of droppings from the pasture at least once a fortnight

· Low stocking density (no more than 1-2 horses per acre)



2. Identifying and monitoring horses with significant parasite burdens

Faecal worm egg counts (WEC) are used to identify horses with higher numbers of intestinal parasites. WEC should be first carried out in the spring (March-May) then usually every 2-3 months dependent on the result. It is important that every horse in a group has an individual sample collected.


Horses with high faecal WEC should be treated with a worming medicine. We can advise you on the most appropriate wormer for your situation.


3. Utilising our available chemical treatments in the most effective manner

When required it is important that the most appropriate wormer is used at the correct dose to help to prevent resistance developing.

We are always ready and willing to provide free independent advice on worming and will help design a worming program  for your horse or yard.
