What test is needed to customize a strategic de-worming protocol?
A fecal test identifies worm eggs. Not all worms pass eggs at all times. So your horse could still have a parasite problem that will not be picked up by this test. The fecal test requires certain collection, storage and shipping conditions that can affect the results if degradation occurs. The test isn’t perfect, but when used strategically over a period of time, it can provide useful information.
