(approximately every other month) Intensive treatment required all through the main seasons of transmission*Īlways consult your veterinarian before treatment. Recommended frequency of deworming per yearĢ times per year (or no treatment at all) (late fall after the first killing frost and spring)ģ – 5 times per year (late fall after the first killing frost and spring, plus when needed, usually in the summer season in the warm environments) Will benefit from one additional treatment during the main season of pasture transmission –spring through autumn in the North autumn through spring in the South* Note that this is the minimal treatment for the so-called light shedders. It is strongly recommended to perform a treatment after the first killing frost in the late fall to control bots and another round in the spring with a praziquantel- containing dewormer, which will provide a solid tapeworm control program. Instead, a proper deworming program will be based on the level of infestation and on the climate in your area. There is no longer any fixed time chart or an ideal schedule for equine deworming. This may help prevent further transfer of eggs and larvae between individuals. It may be a good idea to group horses based on the parasite type of infestation they have. This is due to individual immunity, genetics, exposure level, and a variety of other factors. Some horses will carry a lot of worms and others much less. If you test the whole herd individually you may find that not all horses carry the same amount and/or type of parasites. Statistically, horses can be categorized as follows: Number of eggs in a gram of fecal matter (EPG) The fecal test should be done once a year or at least every other year. Every horse from the herd should be tested, but if the group is very large, then a proportionate test group may be used to gather samples from. The test is relatively inexpensive, and can provide a solid basis for choosing the right product that will ensure an effective deworming treatment. That is why every treatment should start with analyzing fecal samples. Some of these can be identified easily, others not so much. Strongyles, roundworms, bots, pinworms, and tapeworms are some of the parasites that veterinarians and horse owners deal with. For example, the so called dewormer “rotation” is no longer an acceptable practice. As parasites can pose a very serious threat to a horse’s health, including fatal situations, it is apparent that the commonly accepted approach to parasite control should be reconsidered. The recent increase in parasite resistance to commonly used deworming products has left the equine community concerned and in search of ways to slow down, if not reverse, the alarming trend.

Guidelines are specified separately for adult and young horses (less than 3 years). There is no such thing as a “one size fits all” program. Ultimately, each farm (with veterinary guidance) should develop its own program tailored to the specific needs of the farm and each animal. It is important to keep in mind that the information contained within these guidelines are suggestions there are many variations of these suggested programs that will still meet the same goals and follow the same principles. ![]() In 2019, these guidelines went through a rigorous review with the committee and former subcommittee and were updated. In response to this need, the AAEP’s Parasite Control Subcommittee of the Infectious Disease Committee in 2013 produced a comprehensive set of recommendations for helping veterinarians develop improved strategies and programs for parasite control in horses of all ages. However, much has changed in this time, necessitating a re-examination of recommendations for parasite control.
