A lot has changed in recent years in regards to how often we should deworm horses and what we should use.  Due to the development of resistance against our existing deworming medications and no new class of medications on the horizon, the new recommendations revolve around 'strategic deworming.'

This means we deworm horses less often and we deworm them as individuals.

Recent research has shown that horses fall into one of three classes of parasite egg shedders.  There are low shedders, moderate shedders, and heavy shedders.  Genetics and individual variation determines which they are.  Once a horse is found to be a low shedder - he will always be a low shedder, and so on. 

How do you know which one your horse is?  A fecal egg count!

This is a test that we run right here in our clinic.  We need a fresh manure sample (one manure ball is adequate) from each horse on your farm.  You can collect this sample into a plastic baggie and label it with your name and your horse's name and the date.  One of our licensed veterinary technicians will then perform the test and we will call you with the results.
