Properly controlling internal parasites in horses isn’t as simple as we once thought. Gone are the days of rotational deworming neatly outlined on the calendar. Instead, veterinarians have a host of new recommendations for controlling internal parasites in horses without contributing to anthelmintic (deworming drug) resistance in parasites, an increasing problem.

If you’re a bit confused about these recommendations and what they mean for you and your horse, you’re not alone! To make the transition to targeted deworming easier, we’ve compiled 10 equine deworming and parasite resources available free on TheHorse.com. Find more information on the “Deworming and Internal Parasites” page or by searching “deworming” or “parasites” on TheHorse.com.

SPECIAL REPORT: 14 Up-to-Date Horse Deworming Facts No doubt about it, parasite control in horses has changed dramatically during the past decade. Gone are the days of rotational deworming scheduled at regular intervals throughout the year. Now, scientists are studying parasite resistance to common anthelmintic drugs, and veterinarians are offering clients more targeted equine parasite control solutions. Download Now

ARTICLE: What is Your Horse's Fecal Egg Count Telling You? You’ve finally accepted your veterinarian’s advice and abandoned traditional deworming practices for an evidence-based program that has regular fecal examination (fecal egg count, or FEC) results as its basis. But change is always a little scary, and you want to understand your new program as thoroughly as possible. So, what do the results of an FEC tell you about an individual horse? The answer is “it depends.” Read More

ARTICLE: Parasite Control: An Update Internal parasites of horses have been recognized for centuries. Beginning in the 1940s and extending to the 1980s, new classes of antiparasitic compounds were developed approximately every 10 years. However, currently in the United States, only benzimidazoles (fenbendazole and oxibendazole), tetrahydropyrimidines (pyrantel pamoate and pyrantel tartrate), and macrocyclic lactones (ivermectin and moxidectin alone or each combined with praziquantel) are commercially available for parasite control in horses.

FARM CALL: Parasite Control Recommendations for Boarded Horses What’s the best way to go about making the decision to deworm if my horse is boarded at a large facility? For instance, historically my horse has tested as a low to no shedder, and he only goes out with two other horses. Should we have the recommended three fecal test this year and then decide? Are there other considerations to keep in mind? Read More

ARTICLE: Do Foals, Yearlings Need Fecal Egg Counts of Zero? Foals and yearlings are the groups of horses most susceptible to parasitic disease. As such, they’re also treated most intensively with deworming agents. But do we really need to eliminate all parasites from young horses’ bodies? Read More

ARTICLE: Vaccines, Dewormers, and Nutrition for Senior Horses More and more horses are staying active into their golden years, but just because a horse is young-at-heart doesn't mean his body is just as fresh. Fortunately, researchers are on the hunt for ways we can help keep geriatric horses' bodies up to par. Read More

COMMENTARY: The Future of Parasite Control? Today, we can expect resistance to at least one drug class to be present in every equine operation across the world, and an overwhelming majority will feature multidrug resistance. With only three classes to choose between, we’re running out of treatment options. A pertinent question to ask is how to tackle this emerging crisis and what to expect in the future. Read More

ARTICLE: Pasture Management for Parasite Control Horses grazing lush green pastures paint an idyllic picture. But things might not be as serene as they seem—these animals could be ingesting harmful parasites with each bite. Researchers have shown that on most horse farms the clear majority of “internal” parasites lurk in pastures, waiting for horses to consume them. The objective of parasite control programs is to interrupt transmission by targeting specific parasites at the proper times, which vary by climate. Because worms have developed (and are continuing to build) resistance to deworming drugs, horse owners should investigate other feasible options for parasite control—for example, pasture management.
