Faecal Egg counting is a great way of determining how many egg-laying worms are at work in your horses' gut. Some worms become "encysted" before they mature to egg laying size and these cannot be detected in a Faecal Egg Count.
Tapeworm eggs may sometimes be seen in a Faecal Egg Count but the eggs are often contained in a "Proglottid" a kind of sac which has broken away from the main body, so a clear count does not necessarily mean the horse does not have Tapeworms. Of course, if a Tapeworm Egg is discovered, then the right Anthelmintec can be given to take care of them.
How do I get my horse tested?
Collect a manure sample from the horse to be tested. Take several pinches from different parts of the pile and select it from where the manure hasn't been in contact with the ground or bedding.
Bring or send the sample to me at the address at the bottom of the page. In warm weather, if being sent through the post, the sample needs to be cooled down in the fridge to prevent the eggs from hatching. Enclose the payment of £5 for each sample (no charge for rescues) and send it off to me.
As soon as the sample arrives, I will check it and tell you the Eggs Per Gram (EPG), you will then know if any action needs to be taken. If you bring the sample yourself, I will show you the result.
Generally, if the horse has a count of 200epg or less, it's safe not to worm as the burden is minimal and a light infestation will help boost immunity.
