From: Horse Care
Horse worms (as internal parasites) range in significance in relation to their affect on a horses health, from a minor loss in weight or loss of blood or irriatation and growths, to possible death.
It is essential therefore for the horse carer to understand worms and deal with them properly themselves with product advice from manufacturers guidelines, or to take expert advice from a veterinary surgeon or very knowledgeable supplier.
All horses will have some internal parasites at all stages in their life, and it often requires laboratory tests to discover these in the early stages. However, since prevention is better than cure, worming is usually carried out as a regular preventative measure.
How Horses Get Worms
Horses get worms, as worms can live as eggs or larvae in the grazing pasture, in feed, in a mares milk and on their coats, via flying insects, and in their living environment generally.
Worms therefore spread amongst horses by contamination via faeces, feeding, flying insect bites and egg laying, and direct contact. For example some are intestinal parasites and their method of breeding and spreading is via the horse host, and the contaminate product of the host system ie faeces.
It should be clear therefore that where several horses live in the same locations, it is not difficult to end up in a multi-contaminated situation. Shared pastures, stable blocks and yards, feed buckets, and horses coming into contact with each other are all potential risks for spreadng worm infestation. Hygiene is as prerequisite to horse health as to human health. In addition other measures are needed for the control of worms.
Horse wormers are sold as specialized drenches, as bot drenches (bots are in fact flies) or broad spectrum drenches. These usually provide in a single application the necessary chemicals to deal with a significant portion of the infestation. To deal most effectively with all worm types, therefore, a horse worming programme should be developed.
