worms-horses-what-you-must-know

Worms, or internal parasites, can and will adversely affect your horse’s health. If left untreated, a horse with worms can develop serious, untreatable damage to its internal organs which will eventually lead to death.

The most common internal parasites are roundworms, small strongyles, tapeworms, bots, pinworms, large strongyles, and threadworms. The worms that pose the biggest threat to a horse’s health are roundworms, small strongyles, and tapeworms.

How do worms enter a horse’s body?

Typically, the horse ingests the parasite’s eggs or larvae while grazing. Once inside the horse’s digestive system, the eggs or larvae mature into adulthood.

What are the symptoms of worms in horses?

A dull coat, poor performance, weakness, and depression are the most common symptoms your horse is suffering from internal parasites. Internal parasites in horses can lead to death.

How can worms in horses be treated?

According to the American Association of Equine Practitioners (AAEP), “In terms of management priorities establishing an effective parasite control program is probably second only to supplying the horse with clean, plentiful water and high-quality feed.”* Therefore, administering deworming medication is one of the best defenses against internal parasites in horses. This can easily be accomplished by a developing a deworming schedule.

How do you develop a deworming schedule?

An effective deworming schedule should take into account the horse’s size and age as well as the season, climate and stable location. Horse dewormers should be used either daily or seasonally throughout the year. Horse dewormers are available in pellets, liquid suspensions, or pastes.

Daily Horse Dewormers: the daily use of dewormers prevents harmful parasites infestations. Daily dewormers paralyze parasites in the digestive tract, and move them harmlessly out of the horse’s system.

Seasonal Horse Dewormers: administering a systematic, seasonal deworming program can control these harmful parasites. It is recommended that you should deworm horses six times a year, rotating different compounds (such as ivermectin, fenbendazole, and pyrantel pamoate) based on seasonal parasite prevalence.
