How often does an adult horse have to be wormed?

Answer 1

For a normal horse, an adult equine should be wormed about every 6-8 weeks. (about 5-6 times/year) When your horse is pot-bellied, dull faced, or just not itself, you need to deworm them even if its not time.

Answer 2

It depends on the wormer and whether they are kept on the same pasture or not. Certain wormers need to be given at certain times of the year to target certain worms. You should rotate different wormers each year to prevent risk of resistance to the wormer building up. The key thing to remember is to never over-do it, like feeding wormer daily in the horses feed, because they will not build up sufficient protection against bots and tapeworms.

See your local equine veterinarian for different wormers you should give your horse[s] at certain times of the year. Also make a yearly/monthly schedule so you know when the right time is to worm your horse.

Answer 3

The answer to this question isn't simple. It depend on the age of the horse, if the horse has been dewormed previously and if so what deworming drug was last used, and the type of environmental and management conditions (stalling, dry lots, pasturing, feces removal) that the horse is in. In some instances, it also depends on the goal of checking for parasites. Fecal exams are done more frequently (before deworming and 10-14 days after deworming) to assess the efficacy of the drug used and determine if there is a resistance problem. Fecal exams to determine the need for deworming may need to be done as frequently as 4 weeks after the last deworming or as long as 16 weeks after the last deworming.

Answer 4

On most packages of deworming product you will find a label that gives you the minimum age at which you can begin using the product and how often. However nowadays due to parasite resistance it is best to consult with a equine veterinarian and have them do a fecal egg count test to determine when and if the horse needs to be dewormed and what product to use.

Answer 5

A horse should be wormed about every 6 to 8 weeks.

Answer 6

You should worm a horse every 6 weeks and rotate your dewormers each time.
