equine parasites

A worm egg count for horses will accurately detect strongyle roundworms - these are the most common equine parasite and can cause serious problems in all ages.


But - we can't always detect tapeworms, pinworms or stomach bots. These are less frequent and can be easily monitored for in other ways

Recommended testing frequency:  3 times per year

Highest risk periods: mild, wet weather

Horse / Pony / Donkey WEC: £12.50

For up to 5 named samples: this can be a mix&match of species across the farm

or £10 for a single sample


large Strongyles

aka the Nematodes:

Strongylus vulgaris


Mostly asymptomatic

Rarely cause anaemia


larval migration can cause aneurysms, especially of the cranial mesenteric artery - these can suddenly bleed causing severe colic or death


Small Strongyles

aka nematodes:

Cyathostomes, Cylicocyclus, Cylicocephalus, Gyalocephalus




poor coat quality

intermittent enteritis - diarrhoea and poor appetite


aka anoplocephala


Look horrible when wriggling out - but surprisingly harmless!

Heavy burdens in under 2 year olds cause:


Reduced gut motility

Only detected through saliva kits - you can order these through the internet. We recommend worming all under 2 year olds with a tapewormer every 6 months


aka Oxyuris equi


Itchiness around the bottom

tail rubbing

tail nibbling

behavioural problems and agitation

Usually shows on a Faecal Worm Egg Count - but not always so look closely for tiny wriggly worms around your horse's anus
