How to Use Ivomec wormer in goats

Updated February 21, 2017

Goats are relatively easy to care for and have been kept by humans for centuries for their milk, meat and hides. But goats are prone to internal parasites such as roundworms, hookworms and whipworms. Ivomec, a liquid wormer that has long been used in cattle to control parasite infestations, has been shown to kill these same parasites in goats. Using Ivomec wormer in goats is not difficult and can help restore health and vitality to your herd with a single dose.

Check your goat herd for signs of parasite infestation. Goats with worms will often have pale gums due to anaemia, a dull, lifeless coat and severe bouts of diarrhoea. Schedule a visit with your vet to have a fecal sample tested for parasites if you suspect your goats have a parasite infestation.

Catch one of your goats with a halter and lead. Many goats are reluctant to be handled by humans, so move slowly and touch your goats gently to prevent frightening them. Slide the halter over the goat's head and buckle it behind his ears, holding the lead firmly to keep him from escaping while you medicate him.

Weigh each goat on your scale and fill your syringe with the proper dose of Ivomec. Ivomec is dispensed according to the weight of your goats, with each goat requiring 1 ml of liquid per 22.7 kg of weight (0.03 fl oz per 50 lb). Ivomec can be used on pregnant and young goats, as long as the dose is adjusted correctly.

Hold the syringe in one hand and place it in the goat's mouth, as far back on the tongue as possible to prevent him from spitting it out. Depress the syringe slowly to make sure the goat swallows the entire dose. The goat may react to the bitter taste of the Ivomec by trying to pull away from you. So hold the lead firmly to prevent his escape.

Offer your goat a handful of grain or other treat to help get the wormer taste out of his mouth and show him that being handled is a positive experience. Catch your next goat and repeat the worming process until you have medicated your whole herd.


You should see results within a week or two of worming. Your herd will have more solid stool and shiny coats and will eagerly eat their feed. The worming process should be repeated every three to four months.


Never give your goat too much wormer. Ivomec is a chemical, and an overdose can cause serious health problems such as stumbling, lack of coordination and seizures in your goats.
