Don’t Forget to Re-Test ~ F.E.C.R.T. Matters

You’ve done a wonderful job and completed your first round of equine fecal worm egg count tests on your horse herd and administered appropriate deworming treatments as needed based on the results. Brilliant.

If you’ve taken advantage of working with a professional testing laboratory directly, you’ll probably receive that friendly reminder that it is time to retest. The F.E.C.R.T. or fecal egg count reduction test is not something to forget about or put on the back burner. Why not?

Simply put, you can’t assume that the treatment you administered has worked. For example, just because you dewormed your horses it doesn’t mean that those intrepid alimentary canal explorers, the small strongyle worms, have been eradicated. In fact there is no such thing as a zero equine parasite population within the host.

There is a high likelihood that small strongyles may still be present in their encysted stage hiding in the mucosal layer of the horse’s gut. They have therefore avoided the destructive action the dewormer has exacted on those worms that were en route as worm eggs through the horse’s intestinal system. The small strongyles burrow into the mucosal lining of the large intestine and normally become encysted there for 2-3 weeks, where they cause inflammation of the wall of the intestine. They can remain encysted and viable for 2.5 years! The adult small strongyles do not cause the horses much problem even when in high numbers.

Remember it’s called life cycle not life stasis. As with any living organism, it is important to recognize that there is a life ‘cycle’.

You must also consider the notion that your horse might harbor worms that are resistant to the dewormer protocol that you utilized. As you are unable to see inside your horse the F.E.C.R.T. provides a valuable resource to help you determine the success of your mission to minimize the internal parasite population in your horse.

Next time that reminder pops into your inbox be sure to take action. If you are not already working directly with a laboratory then consider it. Their auto-fill and reminder programs are very helpful in keeping you on track with your targeted worm control program and make our busy lives as horse owners much easier.
