Did your vet discourage you from doing worm egg counts or discourage you from doing worm egg counts occasionally, stopping worming your horse and hoping for the best? Worm egg counts can't ever replace the need for effective treatments and pasture management. You should look at worm egg counts as an additional tool rather than a replacement for good pasture managment and worming treatments. The key is to use worm egg counts for monitoring the success of your existing programme and identify the need to make any changes as required. Worm egg counts are also the best way to identify worm resistance developing to treatments. If you are doing no monitoring, how can you be sure that the existing system is working effectively to keep worm burdens under control? Many Worm Watch clients are surprised to find worm burdens are present in their horses - had they not monitored, they would not have known there was a problem with the current system until the burdens built up to such a level that they were seeing worm-related disease. Monitoring alerts you to problems early so that you can intervene and make the changes needed before it becomes a "big" problem and horses are sick.
