Dealing with Equine Parasites


Equine worms are organisms that inhabit the horse’s body. They deprive the animal of oxygen and nutrients and can severely affect the horse’s health. Every horse tolerates parasites differently, regardless of their management, but there are outside factors that lead to worsening conditions. Over-grazing pastures, uncleaned stalls or pens, low nutrient feeds, and horses left untreated are some of the contributors to harmful parasite burdens.


It is estimated that there are over 150 species of internal parasites that can use the horse as a suitable host. Of these, there are 7 categories that infect the greatest number of horses and have the potential to do the most harm. During the parasite life cycle, they burrow through the horse’s body, eating their way through tissue, causing damage to many organs and compromising several body systems. When infested horses are left untreated, they can have scarred tissues which can reduce oxygen exchange in the lungs, inhibit liver function, block nutrient absorption and leave the animal at a much higher risk for colic.


Pasture rotation or cross-grazing by other animals will lower repeated exposure to parasites and usually stimulate an immune response. If your horse is in a smaller, confined environment, regular manure removal is essential for parasite control. Depending on your geographical location, different protocols for deworming have been recommended. If you are in a colder climate with a shorter growing season, you may typically deworm twice a year. If you are in a hotter or wetter climate, you may deworm as often as every other month. Additionally, many horse owners choose to use a daily deworming product, regardless of their climate. It is customary to treat with different products to cover different types of worms during different seasons. The strategy of rotational worming involves using specific types of dewormers at a particular time of year, based on the nature of the parasite’s life cycle and activity.


Parasitic drug resistance has become a growing challenge. Worms are surviving through deworming treatments and becoming a greater issue. Widespread drug resistance is being seen across the country in all species, with all parasite types, and with all drug classes. Strategic deworming, which involves taking fecal samples and treating for specific parasites, may not be an option for many horse owners because it requires additional work and higher cost. It has been far easier to rotate “chemical class” dewormers and increase treatments throughout the year, assuming the issue.


Obviously, pasture management is beneficial in many ways beyond parasite control. Keeping your stalls and smaller lots cleaned regularly will minimize much of the parasite concern issues. Remember, every animal tolerates parasites differently. You may notice in a herd situation where all horses are fed and treated for parasites equally, 20% will show noticeably poorer body conditions. This is because the 20% are carrying 80% of the infestation. If you pull fecal samples of your whole herd, you will see this reflected in the egg count results.


The proprietary blend and balance of the ingredients in Whisper Works Natural Horse Wormer® work completely differently than drug or herbal dewormers. It will not promote parasite resistance, making it a wonderful alternative to outdated and ineffective protocols. Here at Whisper Works we are conducting ongoing studies to show more definitive findings. Currently, we have fecal testing and blood work showing a decrease in fecal egg count, a lowering in white blood cells, and an increase in red blood cells after treatment. This indicates the parasites that are resistant to other deworming products are no longer present after the horse is treated with Whisper Works Natural Horse Wormer®. The blood work indicates a diminished threat of infection and an increased ability to carry oxygen throughout the body.


Customers are very excited and happy to report complete body condition improvement after treating their horses with Whisper Works Natural Horse Wormer®. They have sent in pictures of manure dropped in the third and fourth days of treatment harboring massive amounts of large and small strongyles, as well as boty larva, indicating significant evacuation of parasite burdens. This product helps support a healthy and naturally worm and parasite free bodily system.


As with any product, we recommend that you consult with your veterinarian before using Whisper Works Natural Horse Wormer®. Treatment may need to be adjusted in certain special situations. This may include, but is not limited to, horses in poor health, horses not formally on a regular deworming program, horses intended for breeding, pregnant or lactating mares and horses under 750 lbs. Should you have any further questions or concerns, our product support line is available at 1-833-977-7979.
