Dewormers

The Best Deworming Protocol for your Horse

Taking care of your horse's health begins on the inside, and managing parasites with dewormer is an important step in maintaining optimal digestive health. Internal parasites rob your horse of nutrients and can create a roadblock in your horse's intestinal tract.. A dull coat, difficulty maintaining weight, and a higher risk of colic are associated with a heavy internal parasite load. Parasite control is a critical part of horse health and Corro has everything you need to establish an effective worming routine.

What are the Common Internal Parasites for Horses?

Large strongyles and small strongyles are ascarids. This family of worms lives in the large intestine as adults

The large intestine also hosts  roundworms, but this type of parasite is typically only found in foals and young horses under two years old.

Where the large and small intestines meet is where you will find tapeworms. When tapeworms take up residence here, colic can result. Tapeworms are transmitted by microscopic mites that your horse eats.

Horses may become infected with lungworms. However, these are a more significant threat to donkeys, as they rarely mature and reproduce in a horse.

Threadworms are rare in horses. Their larvae, called microfilaria, travel up the neck and shoulders of horses and can create itching and hair loss.

Types of Deworming Medications

Most worming medications are paste dewormers. They are easy to use in a single dose with no mess.

The top medication for parasite control is ivermectin and ivermectin paste. This dewormer regulates over 40 internal parasites, including strongyles, pinworms, bots, threadworms, and lungworms. Farnam's Evercare and Durvet's Ivermectin paste are great options. Durvet's wormer has an apple flavor for the picky horse.

Pyrantel and pyrantel pamoate wormers target strongyles, pinworms, and roundworms. Praziquantel targets tapeworms in horses and is usually packaged in conjunction with other medications. Bimeda Equimax and Zimecterin Gold both contain praziquantel and ivermectin.

Quest Plus Gel from Zoetis (formerly Pfizer) is moxidectin plus praziquantel. The moxidectin targets strongyles, bots, and pinworms.

For the control of small and large strongyles, roundworms, and pinworms, look for Strongid and Strongid c 2X.

Oxibendazole and fenbendazole are types of drugs in the benzimidazole class. Small strongyles are now resistant to these medications. Merck SafeGuard and Panacur are fenbendazoles, and the Panacur PowerPac can be used for heavy loads of parasites over several days. Zoetis makes Anthelcide Eq with oxibendazole, which works similarly.

Frequently Asked Questions about Horse Wormers

How do I do a fecal egg test to check my horse's parasite load?

Your veterinarian can check your horse's count for you. A fecal egg count is usually done in the spring and fall and takes a few days for results to come back. A few fecal balls from your horse's manure are collected in a sealed bag and sent to a specialty laboratory. Then your vet can make a treatment plan for your horse with the specific paste wormers your horse needs.

Creating a deworming schedule for your horse also depends on the climate, your horse's overall health, and even your horse's age. Foals and young horses are more susceptible to parasites than older horses.

How will I know if the dewormer I use has worked?

A preliminary fecal egg count test is a baseline. After your give, the dewormer, wait two weeks and test again. Sometimes, a different brand or formulation is needed. You might need to try multiple doses instead of a single dose.

Why are rotational worming schedules not recommended by veterinarians anymore?

Over the years, intestinal parasites have become resistant to current medications, and there are no new medications in development. Rotational deworming is similar to the over-use of antibiotics, which creates powerful parasites and powerful bacteria. The strategic use of deworming medications following a fecal egg count test is now the standard practice.
