“Make sure you choose a product that is licensed to treat encysted redworms if these are the worms you are targeting and that you give the correct dose, by weighing your horse beforehand, as this will help preserve the efficacy of the drug you use.”

Treat for encysted small redworm this autumn.

Autumn is the time of year to treat horses for encysted small redworm. These parasites are the most common worms found in horses today. They can pose very serious health risks to horses and it’s important to make sure that they are treated properly during the autumn or early winter. Hyperdrug offer a range of wormers which are effective against small encysted redworm including Equest and Equest Pramox.

Small redworms can grow up to 2.5cm in length and are thin and reddish in colour. Small redworm eggs are passed in the faeces and then hatch on the pasture and continue to develop into more advanced larval stages before being ingested by the horse as it grazes. The larvae burrow deeply into the wall of the gut where they encyst and may account for up to 90% of the redworm burden in horses1. Encysted small redworm will not show up in a Faecal Worm Egg Count - even if the horse has shown a negative or low count it could still be harbouring several million encysted small redworms.

Encysted small redworms can remain dormant inside a horse for up to two years, but they usually ‘wake-up’ in late winter or early spring, developing and emerging from the gut wall all at the same time. In severe infestations mass emergence can lead to a disease syndrome known as ‘larval cyathostominosis’, causing diarrhoea and colic with up to a 50% mortality rate3. Young horses of less than six years of age are likely to be at higher risk of the disease3 but small redworm can cause life-threatening illness at any time of year and in any age of horse.

“Treating encysted small redworms successfully in the late autumn or early winter is important to avoid the risk of larval cyathostominosis, says Darren Walton, manager at Hyperdrug. “Make sure you choose a product that is licensed to treat encysted redworms if these are the worms you are targeting and that you give the correct dose, by weighing your horse beforehand, as this will help preserve the efficacy of the drug you use.” Wormers licensed for treatment for small encysted red worm include Equest, Equest Pramox as a single dose. Alternatively Panacur Equine Guard when used over five days will treat the redworm which emerge into the gut during treatment.
