Horse Care - Worms

Spring and Summer are an important time to consider your horse's drenching program. Horses can be affected by a number of different intestinal worms including large and small strongyles, thread worm and bots. They can cause mild disease like weight loss to severe and life threatening colic.

 

What signs will my horse show if it has worms?

* Poor growth
* Weight loss
* Tail rubbing
* Diarrhoea
* Colic
* Coughing in young foals
* Bot fly eggs

 

What do I do?

* Your vet can examine some of your horse's faeces for worm eggs
* You need to drench your horse. It is really important to use the right drench at the right dose for your horses weight. Under dosing or the wrong drench will not kill all of the worms and allow resistance to develop.
* In general, use a mectin drench in Autumn/Winter and a Benzimiazole (BZ) drench in Spring/Summer.
* Put your horse onto a fresh paddock after drenching. This will stop the horse re-infecting itself from eating contaminated pasture.
* Talk to your vet about how frequently you need to drench your horse. Some that are kept on pasture with a high stocking density will need to be drenched every 6 weeks, others with low stocking density will need it less frequently.
* Harrow the paddock and spell during hot and dry conditions to kill worm larvae 6-8 weeks. This creates a clean pasture that you can put your horse back into after drenching.
* If practical remove manure to prevent eggs hatching onto pasture.
