How Often Should You Deworm A Horse? (TOP 5 Tips)

1. Each horse should be dewormed every 6 months with an Ivermectin product (Spring and Fall). Ivermectin is a larvicidal (will kill parasite larvae), and if used every 6 months on each horse, large strongyles will be eliminated from your farm.

What is the best worming schedule for horses?

Traditionally horses have been dewormed every two months, but this has led to parasite resistance among horses. For this reason, we recommend performing Fecal Egg Counts (FEG) in the spring (ideally spring and fall) to determine the number of eggs a horse has in its manure.

Can you deworm a horse too much?

While different parasites can be beneficial to keep the gut healthy, an overload of worms can cause a wide variety of potentially dangerous problems for your horse. Setting a proper deworming schedule can help keep horses healthy and minimize the risk of spreading worm contamination.

How do you tell if a horse needs to be dewormed?

Common signs a horse needs worming are weight loss, diarrhea, fatigue, itchy rear-end, and an off-color or unhealthy coat. Here is a list of signs a horse infected with worms may display:

Diarrhea.
Loss of hair around its tail from rubbing.
Not eating normally.
Losing weight.
Lack of energy, sluggish.
Anemia.
Colic.
Impaction.

How soon after worming a horse can you worm again?

Many of the data sheets for wormers, notably those that contain praziquantel, ivermectin or moxidectin, advise stabling for two – three days after worming.

What month do you worm horses?

All horses should be wormed in the late autumn with a combined round/tape wormer to remove bots, tapeworms and any adult roundworms. 4. For many horses once a year worming will be sufficient. Horses identified with higher worm burdens will need to be wormed more frequently.

How much does it cost to deworm a horse?

The cost is $12 for each quantitative fecal egg count and approximately $15.50 for each dewormer. Total yearly cost is $55.00 per year. Other horse owners prefer the older way to deworm a horse by administering a paste dewormer every 8 weeks at a cost of $93.00 per year.

What are the signs that a horse has worms?

Symptoms of worm infections in horses

Weight loss.
Colic.
Diarrhea or constipation.
Rough hair coat.
Poor growth in foals.
Respiratory problems. (nasal discharge, cough)

Can I deworm my horse twice?

Here are the basics: You will need to deworm all horses twice yearly (after the first frost and again in the spring) with an ivermectin or moxidectin product to kill large strongyles and bots.

Can you worm a horse twice?

Deworming every couple of months, or rotating dewormers each time, or every other year, do not control internal parasites effectively. While the goal once was to rid an individual horse of all parasites, it’s impossible.

Can you see worms in horse poop?

You can’t see them because the eggs are too small. But occasionally, you may see internal parasites in the adult or larva form that have worked their way through your horse’s digestive system and into the manure.

What causes a horse to get worms?

Horses can get worms from their grazing environment or from the feces of other horses. Horses pick up Roundworms (ascarids) from grazing in ears with eggs from infected manure. The larva spread to the liver and lungs. Horses will cough up the immature worms and swallow them where they grow and lay eggs.

How long does it take to get rid of worms in horses?

Worming throughout the year There are two types of wormer that can be used for this, fenbendazole or moxidectin based wormers. Horses only need treating for tapeworm twice a year as the lifecycle takes six months to complete.

How do you deworm a horse naturally?

How can we effectively and healthfully prevent or eliminate worms in our horses? The answer is with love, organically! Some of the herbs that are proven to be highly effective at expelling or preventing infestation of parasites are peppermint, chamomile, anise, thyme, dulse, neem, elecampane, cinnamon, and garlic.

What horse wormer kills all worms?

Prominent in this class, ivermectin is effective against adults of all the common equine parasites except tapeworms. It is also effective against some larvae and is credited with greatly reducing colic associated with the migrating larvae of Strongylus spp., but it does not kill encysted small strongyle larvae.

How Often Should I Deworm My Horses?

Internal parasites are a normal component of the digestive systems of horses. While certain parasites might be useful in maintaining the health of the intestine, an overabundance of worms can create a broad range of potentially serious difficulties for your horse’s health and wellbeing. Setting up a good deworming regimen can assist to keep horses healthy while also reducing the likelihood of worm infection spreading.

How Horses Get Worms

Worms are extremely easily picked up by horses. Feces from the animals’ grazing pastures include both mature worms and larvae, which are discovered in the feces. Horses ingest the worms and pass them back into their digestive tracts along with the grass they eat, so keeping the cycle alive and well. Even when kept in a barn, horses can become infected with worms through their feces, which can contaminate feed and bedding. Horses are susceptible to a number of different forms of worms, including bloodworms, roundworms, tapeworms, bots, and pinworms.

Increased appetite
Weight loss that occurs suddenly
A dull or out of condition coat
Lethargy
Anemia
Diarrheal obstruction
Intestinal blockage.

In extreme circumstances, symptoms might increase to the point where they are potentially lethal. Veterinary diagnosis is recommended if you believe your horse has worms. This will help you discover the particular type of worms implicated as well as the degree of contamination, which will help you develop an appropriate treatment strategy. To check for worms, a veterinarian will do a fecal examination or a blood test on the animal.

How Often to Deworm Your Horse

A single, perfect horse deworming program that will work for every animal in every environment or for every type of worm does not exist, nor will there ever be. Traditionally, deworming regimens included treatments every two months, with the types of dewormers being rotated to reduce the likelihood of parasites developing resistance to the chemicals. Some horses, on the other hand, can be kept in excellent condition by merely deworming them in the spring and fall. In some cases, other animals may require continuing deworming treatments to be given to their feed, particularly to avoid the reappearance of worms after the initial problem has been resolved.

As a result, animals that are extremely young or very elderly may require more frequent deworming since their internal barrier to contamination is more vulnerable
Optimal health: Horses in good overall condition may require fewer deworming treatments because they are better equipped to withstand the harmful effects of worms. Smaller herds may require less deworming than larger herds, which may unwittingly contaminate one another. Herd size is also important to consider. Poor Pasture Conditions: A filthy, tiny pasture is more likely to house higher populations of worms than a larger field that has been appropriately treated to reduce parasites. Pasture Management: Climate: Worms grow in warm, damp conditions, therefore horses in cooler, drier climates are less likely to require deworming on a regular basis. When Your Horse Comes into Touch with Unknown Horses: If your horse comes into contact with strange horses at shows or boarding facilities, more regular deworming treatments may be necessary.

Keeping Your Horse Worm-Free

Additionally, it is critical to create a regular deworming regimen for your horse and to take easy precautions to reduce the risk of worm infestation. This will allow you to use deworming treatments less regularly, which will prevent the parasites from becoming resistant to the deworming treatments in the future. In order to keep your horse free of worms.

Maintain a regular harrowing schedule in the pasture to break up manure and enable it to dry out, killing any worms or larvae that may be present. Mow the pasture frequently to expose the dung and worms to more direct sunlight and drier circumstances that are less conducive to worm growth and reproduction. Ensure that manure is dumped in a location that is separate from where your horse will feed or graze in order to reduce the possibility of contamination. If feasible, rotate pastures every few weeks, allowing each pasture to remain unused for 6-8 weeks before returning horses to the herd. Reduce the number of horses in each field at the same time to reduce waste and cross-contamination between animals. Elevated feeders should be used to prevent your horse’s feed from coming into touch with the ground or any surrounding dung, which might lead to contamination.

It is simple to maintain control over these troublesome parasites and to keep your horses healthy throughout the year by developing a deworming regimen that matches your animals’ needs and taking precautions to keep them worm-free.

Equine Deworming Schedule

Not many people are aware that horses have a low number of parasites in their digestive tracts all of the time, and that this is quite normal. The objective of parasite control in horses is to maintain a healthy balance in the number of parasites present so that we do not experience clinical signs (weight loss, colic), while at the same time avoiding the development of drug resistance. Horses have traditionally been dewormed every two months, however this has resulted in parasite resistance among horses as a result of the practice.

In order to assess the quantity of eggs present in a horse’s dung, we propose doing Fecal Egg Counts (FEG) in the spring (preferably, both spring and fall).

Red Hills Veterinary Hospital Recommends the Following Paste Deworming Protocol:

Unless otherwise stated, all egg count levels listed below are recommendations based on the average range of counts achieved using the McMaster procedure.

ADULT HORSE SCHEDULE

Prior to deworming in the spring, a fecal egg count is conducted (ideally spring and fall)

Ivermectin (Equell®, Zimectrin®, Rotectin®, IverCare®), moxidectin (Quest®)
SPRING (March) – ivermectin (Equell®, Zimectrin®, Rotectin®, IverCare®)
PREVENTION: Ivermectin with praziquantel (Equimax®, Zimectrin Gold®) or moxidectin with praziquantel (Quest Plus®) in the FALL (October).

MODERATE SHEDDERS (200 – 500 EPG)

Prior to deworming in the spring, a fecal egg count is conducted (ideally spring and fall)

In the spring (March), use ivermectin (such as Equell®, Zimectrin®, Rotectin®, IverCare®, and other brands), or moxidectin (such as Quest®)
In the late summer (July), use ivermectin
In the fall (October), use ivermectin w/praziquantel (such as Equimax®, Zimectrin Gold

HIGH SHEDDERS (500 EPG)

Pre-deworming fecal egg counts are conducted before to deworming in the spring and fall to detect signs of resistance.

Ivermectin (Equell®, Zimectrin®, Rotectin®, IverCare®), moxidectin (Quest®)
SPRING (March) – ivermectin (Equell®, Zimectrin®, Rotectin®, IverCare®)
Ivermectin is used in the summer (June)
Ivermectin with praziquantel is used in the early fall (September) (Equimax®, Zimectrin Gold®)
Moxidectin is used in the late fall (November).

In general, fecal egg counts should be used to assess therapy effectiveness. Unless otherwise specified, the treatment recommendations provided below are broad suggestions based on current medication resistance discoveries from throughout the world. It’s possible that other forms of dewormers will still be useful on your farm, and you can use them if you’ve determined that they’re successful through a fecal egg count reduction test.

FOAL SCHEDULE

Fenbendazole (Panacur) or oxibendazole (Anthelcide) for children under 2 months of age
Four to five months — Fecal egg count to track the incidence of ascarids vs strongyles in the stool. Fenbendazole (Panacur) or oxibendazole (Anthelcide) should be used to treat ascarid infestations. Strongyles should be treated with ivermectin after roughly 5 months. Use ivermectin and praziquantel to treat a tick infestation before the end of the calendar year. Assessing for the presence of ascarids in short yearling feces and treating those found with fenbendazole or oxibendazole should be done as soon as possible. Strongyles should be treated roughly three times with ivermectin throughout the yearling year, followed by one treatment with moxidectin + praziquantel towards the conclusion of the grazing season. Assays to determine treatment effectiveness include fecal egg count reduction tests.

13 guidelines to follow when deworming horses

Equine practitioners are particularly concerned with the control of internal parasites in their patients. The availability of readily available, easily administered, and effective deworming agents, combined with the recognition that a specific parasite, S. vulgaris, can cause a destructive colic problem (verminous arteritis), has resulted in a deworming frenzy, particularly among horse owners and breeders of horses. Parasite resistance, which has developed in part as a result of the frequent deworming, has become a big concern.

Because of prior deworming procedures, parasites that were formerly a major source of worry, such as S.
With adult horses, the focus is currently on small strongyles (cyathostomins), with tapeworms and other parasites thrown in for good measure.
At this time, it is recommended that horses should only be treated if they exhibit indications of a high parasite load.
Due to the fact that horses with a high degree of immunity do not shed many eggs, deworming all horses on the same timetable is not a good idea.
Internal parasites are not efficiently controlled by deworming every couple of months, switching dewormers each time, or deworming every other year, among other methods.
While it was originally the objective to completely eliminate all parasites from a single horse, this is now unachievable.
Some general guidelines are as follows: 1.Horses, particularly those older than three years old, should be handled as individuals rather than as part of a herd or as part of a routine.

If the horse lives alone or in a stable, the frequency of the visits may be reduced or eliminated altogether.

Acaricides such as pyrantel, fenbendazole, and oxibendazole are effective in the treatment of ascarids in young horses.

3.In herd circumstances, fecal egg counts should be utilized to choose moderate and high egg shedders for deworming, with moderate and high egg shedders being selected first.

Not all horses must be tested in order to be qualified.

4.Large shedders very definitely require more than one or two treatments each year, depending on their size.

The administration of any subsequent therapies would be done on an as-needed basis.

deworm at the proper time of year Deworming should be avoided during severe temperatures such as winter or summer, as well as during droughts.

Worm-control efforts should be considered as an annual cycle that begins when the likelihood of worm transmission to horses increases from minimal to likely.

If the time between dewormings is too short, the findings of the fecal egg count will only reflect how effectively the last dewormer performed, rather than measuring how well the horse’s immune system lowered levels of cyathostomin egg shedding during that period. As an illustration:

After receiving moxidectin, you must wait at least 16 weeks before collecting a fecal sample. After using ivermectin, you should wait at least 12 weeks before collecting a fecal sample. Wait at least nine weeks after using benzimidazoles (fenbendazole/oxibendazole or pyrantel) before collecting a fecal sample.

The deworming of stabled horses that do not have access to other equids on pasture may only be necessary on a rare occasion or not at all. 9.When compared to older horses, horses less than three years of age are more susceptible to parasite infestations than older horses. Among the particular recommendations for children are:

Foals should get at least four deworming treatments throughout their first year of life. The first should be performed when the baby is two or three months old, and the second should be performed three months later. Check for parasite eggs before weaning to determine whether or not the foal has parasites
The third and fourth treatments should be considered when the child is nine and twelve months old, respectively, and should target the worms that have been discovered. It is recommended that tapeworm therapy be included in one of the latter treatments. Perform fecal testing on a yearly basis to see how effectively the dewormers are working. It is not recommended to deworm an 8-day-old foal. Worms are not the source of the diarrhea. Recent weaned foals should be sent out on the cleanest pastures. In the case of yearlings and 2-year-olds, they should be treated as high shedders and should have three to four yearly treatments with medications that have been proven to work by a fecal examination.

Deworming should be performed on horses displaying indications of parasitism using either moxidectin, which has shown no evidence of parasite resistance, or a larvicidal regimen of fenbendazole (10 mg/kg for five consecutive days) if possible. Do not rely on dewormers alone to keep your pets healthy. Controlling the environment is essential. Manure should be removed from the pasture rather than being spread there. If there are cattle or goats available, allowing them to rotate onto the horse pastures for a few weeks will aid in the removal of eggs from the pastures.

Tradition dictates that botox therapy be administered 30 days after the first frost occurs.
Diatomaceous earth and other alternate dewormers are not recommended.
There is no single deworming program that works for everyone.
More information may be found on the website of the American Association of Equine Practitioners, which also has recommendations.

When to Deworm your Horse – QUEST® and QUEST® PLUS

WHEN SHOULD YOUR HORSE BE DEWORMED? Every horse is a one-of-a-kind individual. Collaborate with your veterinarian to establish an Individualized Deworming TMprogram for your horse, which should begin with an examination of the fecal egg count (FEC). Establish a baseline fecal egg count for comparison purposes. An FEC test will establish the degree of parasite shedding that is currently present in your horse. The results of the FEC test reflect the number of parasite eggs in one gram. It is possible that less than 200 eggs per gram indicates a minimal danger.

Understand the risk factors associated with parasites in your horse.

These should be discussed with the veterinarian on your team.

Results of the FEC test
Horse’s age
Local climate
Manure removal
Pasture rotation
Pasture population
And more. Lush, overgrown, dry lot or a mix of these types of grassland
Feeding can be done individually or in groups, on or off the ground. Show/performance, recreation, and companionship are some of the ways horses are used. horses are moved throughout the property on a daily basis

Deworming Your Horse Should Be Individualized Following an evaluation of FEC shedding levels and your horse’s individual risk profile, you and your veterinarian will be able to build an Individualized Deworming regimen for your horse to meet his or her needs. Deworming treatments, which target important equine parasites of concern, are recommended by the American Association of Equine Practitioners (AAEP) for all horses in the spring and autumn, according to their guidelines. 1 The American Association of Equine Practitioners (AAEP) recommends high-risk deworming treatment strategies for young horses (ages 3 and younger).

QUEST ® is a single-dose treatment that efficiently cures and controls encysted tiny strongyles.
2,*Autumn DEWORMING —Tapeworm therapy is advised once a year, in the late fall or early winter, when tapeworm transmission has ceased as a result of the winter’s chill.
It is possible that these two treatments are all that is required depending on your horse’s parasite risk factors.
Consult with your veterinarian to have a fecal egg count (FEC) test performed on your horse prior to purchasing a deworming medication.

Use of QUEST Gel or QUEST PLUS Gel in foals younger than 6 months of age, as well as in ill, debilitated, and underweight horses, is not recommended. It is not recommended for usage in other animal species due to the possibility of serious adverse responses, including deaths in dogs.

Deworming Horses

What is the frequency with which you deworm your horses? Infected and breeding parasites may infect and breed in even the most well-cared-for horses, so if you just deworm your horses twice a year, you may be leaving them open to the dangers of parasites that can infect and breed in even the most well-cared-for horses. The season for equine parasites is constantly in season, and they may lay anywhere from 5,000 to 100,000 eggs each day, 365 days per year. It can take up to six months from the time of infection until visible indications show, by which time internal damage may have occurred and may be irreparable.

Choose a Deworming Schedule

When creating a deworming program, you must choose between two main strategies: daily deworming and interval deworming. Daily deworming is the most common strategy.

Daily Deworming

Incorporate a daily dose of the deworming ingredient into your horse’s feed to ensure maximum effectiveness. Dosing is determined by the weight of your horse; it is critical that you obtain an exact weight and that you adhere to the program’s guidelines. You will need to use a botacide wormer such as ivermectin once or twice a year to keep your horses healthy. If you select daily deworming, consult with your veterinarian to determine the most effective plan for your horse’s health.

Interval Deworming

This is purging deworming, which is aimed to rid the horse of the majority of parasites he has been exposed to with a single dosage of wormer paste and water. The importance of timing cannot be overstated, and it is suggested that you deworm every 8 weeks. Using a dewormer too soon may result in the worms being too immature to be impacted by the dewormer. If you treat your horse too late, the worms may have had the opportunity to lay eggs, which may then infest the environment around your horse.

Get Rid of Parasites Before They Become a Problem

The American Association of Equine Practitioners has provided the following recommendations:

Ensure that manure droppings in the pasture are picked up and disposed of at least twice weekly. Frequently mowing and harrowing pastures can help to break up dung mounds and expose parasite eggs and larvae to the outdoors. Allowing other animals, such as sheep or cattle, to graze on pastures will help to rotate pastures and break the life cycles of parasites. Horses should be divided into age groups to decrease exposure to specific parasites and to enhance the effectiveness of the deworming regimen tailored to that age group. To avoid overgrazing and to decrease the amount of fecal pollution per acre, keep the number of horses on the property to a minimum. Feeding hay and grain on a feeder rather than on the ground is recommended. Remove bot eggs from the horse’s haircoat as soon as possible and on a regular basis to avoid consumption. It is important to rotate deworming chemicals rather than merely brand names in order to avoid chemical resistance. Whatever program you select, make a commitment to it.

Foal Schedule

Fenbendazole (Panacur) or oxibendazole (Anthelcide) for children under two months of age
Four to five months — Fecal egg count to track the incidence of ascarids vs strongyles in the stool. Fenbendazole (Panacur) or oxibendazole (Anthelcide) should be used to treat ascarid infestations. Strongyles should be treated with ivermectin after roughly five months. Use ivermectin and praziquantel to treat a tick infestation before the end of the calendar year. Assessing for the presence of ascarids in short yearling feces and treating those found with fenbendazole or oxibendazole should be done as soon as possible. Strongyles should be treated roughly three times with ivermectin throughout the yearling year, followed by one treatment with moxidectin with praziquantel before the conclusion of the grazing season, according to the manufacturer. Assays to determine treatment effectiveness include fecal egg count reduction tests.

Deworming Protocol Guidelines

The following are some of the most essential points and recommendations:

Maintain pasture rotation
Cross-graze grasslands with ruminants wherever possible. Remove manure on a regular basis. During hot and dry weather, harrow or drag pastures and keep horses out for two months. Overstocking pastures should be avoided.

Fecal analysis should be performed at least once a year to assess the effectiveness of parasite management.

Fecal egg count is an estimation of the amount of parasite eggs released by the horse in his feces. Before doing a fecal analysis, consult with your veterinarian to ensure that enough time has gone since your horse’s last deworming for eggs to have re-appeared in the stool. Each dewormer has a different Egg Reappearance Period, so check with your doctor to find out what yours is. Fecal egg count reduction test—depending on the product used, the number of worm eggs in the feces should reduce by 90 percent when evaluated 14 days after deworming.

Once a year, use a dewormer containing praziquantel (such as Zimectrin Gold® or Quest Plus®) to treat for tapeworms. Small strongyles (cyathostomes) are only sensitive to a few different types of dewormers while they are in their encysted larval stage. In light of medication resistance studies throughout the world, moxidectin (Quest) would be the medicine of choice in the vast majority of instances. Enthusiastically treating the encysted larvae is suggested in the fall, at or at the conclusion of the grazing season, just before the animals enter the winter. Don’t keep mares and foals in the same pasture or paddock year after year to save money. There is an increase in the number of ascarid eggs produced, which might survive between years and infect fresh foals born during the spring breeding season

To be clear, the two parasites that cause the most worry in adult horses are tiny strongyles (encysted strongyles, cyathostomes) and tapeworms (see below). The ascarid is the parasite that causes the most worry in young horses. For the best results, consult with your veterinarian and do fecal egg counts to determine: 1) dewormer efficacy in your equine business, 2) the existence of ascarids in young horses, and 3) the presence of weakyle egg shedders at low, medium, and high levels in adult horses.

A surveillance-based deworming program allows for the use of less dewormer, which can save money while also ensuring the effectiveness of the program. TheEquine Servicessection was responsible for its creation. Dr. Martin Nielsen was in charge of editing.

How often should I worm my horse?

Generally speaking, worming should be done every 6-8 weeks. The development of a sustainable worming program for your own property, on the other hand, is quite vital. The health of your horses will be protected if you use effective worm control in conjunction with pasture management. Every animal, including horses, is infected with parasites. When properly maintained, your horse may coexist with worms in a rather peaceful environment. However, if worm loads are not well controlled, they can cause health issues such as colic, diarrhoea, and weight loss.

A faecal egg count reduction test is the most accurate method of determining how frequently you should worm your cattle (FECRT).
It is possible to use an FECRT to not only determine which worms are present in your horses, but also to determine which wormers will be most successful.
To combat worm resistance, you should concentrate your efforts on the most serious parasite risks and make certain that you dose appropriately.
Once you’ve identified which wormers are the most efficient for your property, you must apply the dosage in accordance with your weight.
Worm Preventative Measures To conclude, there are other methods you may take, in addition to worming, to limit the worm population on your property.
Aside from that, resting paddocks during hot, dry weather may keep your horses safe from worms, which flourish in these conditions.

Do I Need a Deworming Schedule for My Horse?

Every 6-8 weeks, worming should be performed. The development of a sustainable worming program for your own property, on the other hand, is critical for success. Horses’ health will be protected if they have access to effective worm control in conjunction with good pasture management. Including horses, parasites may be found in every species. Horses may coexist in relative peace with worms if they are properly controlled. Worm loads, on the other hand, can cause health issues like as colic, diarrhoea, and weight loss if they are not well controlled.

A faecal egg count reduction test is the most accurate method of determining how often you should worm (FECRT).
It is possible to use an FECRT to not only determine which worms are present in your horses, but also to determine which wormers are the most effective.
You should target the most serious parasite dangers and make certain that you dose appropriately in order to combat worm resistance.
You must provide dose according to weight once you have decided which wormers are the most effective for your property.
Preventing Worms is important.
Taking manure out of paddocks at least once a week can help to reduce the number of larvae infesting the pasture.

Maintaining a quarantine to perform an FECRT can also help to prevent the introduction of new worm species into your herd. Interested in learning more about the health of your horse? For our free fortnightly educational reports, please subscribe by clicking here.

There aren’t enough eggs. Approximately half of the horses in a herd will likely be “low contaminators” (also known as “low shedders”), which require little or no parasite treatment, according to Reinemeyer. The number of eggs is on the average side. Horses in a herd that are classified as “moderate contaminators” or “moderate shedders” will lie between the other two groups in terms of their egg-shedding tendencies
They will also produce large quantities of eggs. In addition, Dr. Reinemeyer points out that around 20% of the horses (referred to as ‘high contaminators’) typically have extremely high egg counts, and that this subgroup may potentially shed more total eggs than the rest of herd combined.

It stands to reason that high shedders will require more deworming treatments than low shedders in order to maintain their health. “The majority of management efforts should be concentrated on the herds with the highest concentrations of contaminants,” Dr. Reinemeyer advises. But a planned deworming program disregards all of this and mandates that all horses be treated at the same, equal times,” says the veterinarian.

The problem of resistance in a calendar schedule

Calendar deworming regimens that are “one-size-fits-all” might result in the following problems:

Some parasites will be able to survive. The deworming products will very certainly kill the majority of the parasite population, but not all of it. In Dr. Reinemeyer’s words, “anthelmintic resistance” is a genetic trait of a target parasite that makes it resistant to the activity of a dewormer that has previously been successful in the same worm population. As a genetic characteristic, resistance is passed on to offspring of a resistant worm, according to the researchers.
These parasites that are resistant to treatment reproduce. Because resistant worms in the population are not killed by the current treatment, they have a better chance of reproducing because they are not competing with their regular predators, explains Dr. Reinemeyer. “As a result, the frequency of its resistant genetic traits increases within the population as a whole,” the researchers write.
The cycle begins all over again, only this time it is much worse. Controlling the parasite population that has established itself on the farm might become a significant difficulty as time goes on. In Dr. Reinemeyer’s opinion, the more frequently one deworms, the more advantageous the resistant worms become, at least until they reach a population frequency that results in failures that can be identified in the lab, and maybe on the farm. The author notes that “it’s possible that the only worms permitted to breed would be resistant, therefore increasing their dominance within the worm genetics of that farm” under a particularly stringent, interval-based approach.
It’s more expensive than it should have been.
“It should be evident that this treatment is economically inefficient,” says Dr. Reinemeyer, who points out that the whole herd is dewormed numerous times a year despite the fact that around half of the horses would receive little, if any, benefit from the procedure. “However, the tendency for rote control efforts to select for anthelmintic resistance in the target worm populations has the potential to have a bigger impact than the monetary loss,” he continues.

Testing, testing …

Some parasites will be able to withstand the conditions. Using deworming products, the parasite population will be reduced to a large extent, but not completely eliminated. In Dr. Reinemeyer’s words, “anthelmintic resistance” is a genetic trait of a target parasite that makes it resistant to the activity of a dewormer that had been previously successful in the same worm population. As a genetic characteristic, resistance is passed on to offspring of a resistant worm, which is why it is so effective.

Doctor Reinemeyer adds that because the resistant worms in the population are not killed by the current treatment, they have a better chance of reproducing because they are not competing with their normal prey.” Because of this, the frequency of its resistant genetic features within the population as a whole is increasing.

Controlling the parasite population on a farm can become a significant difficulty over time as the farm grows in size.
Reinemeyer’s opinion, the more frequently one deworms, the more advantageous the resistant worms become, at least until they reach a population frequency that results in failures that can be observed in the lab and perhaps ultimately on the farm.
In Dr.
The tendency for rote control systems to select for anthelmintic resistance in the target worm populations, says the author, “may have a bigger impact than the monetary loss.”

Step one is to do FEC testing. First and foremost, each horse on the site is subjected to an afecal egg count test (FEC). As previously stated, this is used to determine if a horse is a low, moderate, or high shedder. “Typically, a fecal egg count performed about 3 to 4 months after the most recent deworming can be used to determine shedding classification. This test should not be performed during the winter, when egg counts tend to decrease due to the natural cycle of aging among adult worms,” explains Dr. Reinemeyer. FECR testing is the second step. A few months later, the horse is dewormed with a specific substance, and the test is redone as an afecal egg count reduction (FECR) test, which is more accurate. This time, your veterinarian will use the results to compare them to the results of the first test in order to determine how effective the treatment was. As Dr. Reinemeyer points out, “one can only execute an FECR for one dewormer at a time
Assessing the susceptibility of all three chemical classes would need three individual FECRs.” Step 3: Was the experiment successful? If the dewormer is still effective and there is no evidence of resistance, your veterinarian should notice a reduction in parasite eggs of 90 percent or greater, according to the manufacturer. In addition, Dr. Reinemeyer estimates that 98 percent of the time when testing ivermectin or moxidectin will be positive. According to the researchers, “FECR readings of 80 percent or more very likely suggest resistance, whereas values between 80 and 90 percent are ambiguous and should be repeated at some time in the future.” Step 4: ERP testing and evaluation. Finally, the set of tests might offer another figure known as the egg reappearance period, which is calculated based on the results of the previous tests (ERP). As explained by Dr. Reinemeyer, “the ERP measures the amount of time that elapses between an efficient deworming and the horse’s ability to severely pollute its surroundings with new worm egg infestations.

There will be no need to repeat the testing if an individual horse does demonstrate parasite resistance to a certain chemical class. “Antihelmintic resistance is a lifelong condition that will never spontaneously return to susceptible status,” Dr.

Reinemeyer explains. It is OK to continue to use the dewormer, preferably with a selective approach, but it would be prudent to conduct another FECR with that class of compound about every two years if the dewormer is still effective.”

Shedders of a moderate caliber. “Moderate shedders might definitely benefit from one more treatment around the middle of the grazing season (summer in the north, winter in the south),” he continues. High shedders are a good thing. The major targets, according to Dr. Reinemeyer, are “high shedders,” and he may administer one additional treatment to this group throughout the grazing season. He does warn, though, that every horse should spend at least one season without receiving a deworming medication, regardless of environment. “We recommend winter for horses in the northern hemisphere and summer for horses in the southern hemisphere.” Additionally, understanding how fast eggs begin to return following a therapy might be beneficial when dealing with the horse’s ERP. In the case of a high-contaminator horse, Dr. Reinemeyer explains that knowing the ERP would assist to establish the shortest possible gap between consecutive treatments. It is also important to consider the climate. Dr. Reinemeyer says that your geographic location has an impact on the timetable. Despite the fact that some parasites’ life cycles take place outside the horse, he explains that infective stages can survive even in sub-zero temperatures. “Climate does not impact the types of parasites as much as it does the timing of infections with the most common worms in various climates,” he says. “Despite the fact that pastured horses can take up new parasites at any time of year, the overall risk of infection is typically lowest during the warmest days of summer, particularly in the southern United States. Because of these seasonal variations in parasite transmission, parasite management techniques must be tailored to the specific geoclimatic circumstances of each farm “he explains

Work with your veterinarian

The question of “Do I require a deworming regimen for my horse?” has been answered. is…yes. However, in an ideal situation, each horse’s program would be adjusted and personalized to meet his or her specific requirements. The veterinarian who will be treating your horses is obviously going to be an important partner in this process, so make sure to receive specific recommendations for your horses and circumstances. Aside from that, your veterinarian will advise you on which chemical class to use.

How Often do I Need to Deworm My Horse?

Equine owners were eager to adopt new anthelmintic (deworming) remedies when they were first developed and released onto the market in the 1960s and 1970s. They also accepted the practice of deworming their horses on a regular basis throughout the year at that time. However, misuse of deworming medicines over the past five decades has resulted in resistance, which means that worms can acquire genes that allow them to become resistant to the medications. Our capacity to treat horses with worm issues is limited by their resistance.

It is no longer regarded acceptable practice to provide deworming products to your horse without regard for the animal’s needs.
Strategic deworming takes into account all factors, including the parasite life cycle, the horse’s surroundings, and the horse’s health.
As a result of our research, we have discovered that different horses within the same herd will have varying parasite loads.
That is why it is critical to tailor your deworming techniques to the specific needs of each horse in your herd.

Fecal Egg Counts for Horses

The majority of horses only require deworming once or twice a year. Prepare your horses for deworming in the spring by having a fecal egg count (FEC) performed on each of them. When your veterinarian does this process, it will be able to determine the quantity of worm eggs deposited in the horse’s feces, which is an indication of the horse’s parasite load. Your veterinarian will be able to tell you whether or not you need to deworm your horse based on the findings of the test. The use of an adequate deworming treatment on horses is suggested in the late fall, following a strong frost, to prevent worm infestations.

Your local veterinarian may advise you on which deworming medication to use in the autumn based on the parasites that are widespread in your region and what products to avoid using.

Horses that are Vulnerable to Parasites

When pregnant mares are dewormed in the spring, before they give birth, the dewormer should be chosen in accordance with the findings of a fecal egg count. A deworming treatment containing ivermectin should be administered to mothers within 24 hours after giving birth. Foals require deworming on a much more frequent basis than other horses. They should be dewormed with fenbendazole for the first time at two months of age, and then retreated with this product every two months until they are yearlings.

Foals should be dewormed with an ivermectin-type product at the age of 12 months, and then every three to four months afterwards with a product chosen based on their fecal egg counts, according to the manufacturer’s recommendations.

Ensure that your horses have access to clean water at all times and that they are fed high-quality hay and feed. This will help them establish a healthy immune system. Make sure that their vaccinations are up to date, and have your veterinarian do regular dental checks on your pet.

Controlling Parasites in Your Horse’s Environment

It is possible to find parasites in pastures as well, where they develop from eggs in excrement to larvae that can infect your horse. Because parasites require precise temperatures, humidity, and other environmental conditions in order to develop into infective larvae, one effective method of managing them is to interrupt the parasites’ life cycle before they reach your horse’s intestine. Use the following techniques to keep parasites under control:

Pick up the dung and remove it from your horse’s environment as soon as possible. By restricting the number of horses allowed on an acre, you can prevent overgrazing and decrease pasture pollution. If you have a pasture that is currently being utilized for grazing, avoid depositing non-composted dung in it since this technique distributes parasite eggs. Rotate pastures with other species to interrupt the life cycles of parasites and other pests. Because they contain various parasites, young animals should be housed apart from adult animals.

By focusing on high-shedding horses in your herd, keeping your horses’ health in good condition, and regulating their surroundings, you may lessen your reliance on deworming medication and your role to the development of parasite resistance while still keeping your horse healthy.

Deworming your horse

Considering that every horse is an individual, various horses within the same herd will have varying worm (parasite) loads. While the vast majority of horses shed very few worm eggs, a small number of horses shed large quantities of eggs and are therefore more responsible for infecting the remainder of the herd
Yet, It is critical to deworm horses in a planned manner so that owners may target their high-shedding horses wisely and avoid overusing dewormers.

Resistance

Resistance develops as a result of overuse of deworming products. Worms have the ability to produce genes that make them resistant to dewormers, rendering the therapy useless. Our capacity to treat horses with worm issues is limited by their resistance. These problems can cause severe colic and even death in horses that are affected by them.

The majority of horses only require deworming once or twice a year. We recommend that you get a fecal egg count (FEC) done before deworming your dog in the spring. A horse’s feces are sampled using this process, which allows us to count the amount of worm eggs the horse is shedding. On the basis of the results, we will provide a recommendation on whether or not you should deworm your horse. We recommend that horses be dewormed in the late fall, following a heavy frost, with an appropriate deworming product. It is best to consult with your veterinarian about which deworming product to use in the fall, based on the parasites that are prevalent in your area. Although we strongly recommend that you conduct an additional fecal egg count in the fall, many pet owners choose not to perform this second procedure. In many local boarding facilities, a fecal egg count is included in the spring herd health packages that they provide their clients. When pregnant mares are dewormed in the spring, before they give birth, the dewormer should be chosen in accordance with the findings of a fecal egg count. A deworming medication containing ivermectin should be administered to the mother within 24 hours of the birth of the foal
Foals require significantly more frequent deworming than other horses. They should be dewormed with fenbendazole for the first time at two months of age, and then retreated with this product every two months until they are yearlings. When temperatures are below freezing in the prairie provinces, foals do not require deworming throughout the winter. Foals should be dewormed with an ivermectintype product about 12 months of age, and then every three to four months with a product chosen depending on their fecal egg counts.

Roundworms(Parascaris equorum)

As a result of weakened immunity, it is most prevalent in horses less than one year old and in extremely elderly animals. They pass via the trachea and spend their lives in the small intestine. Roundworms in young horses are associated with stunted growth and development, as well as respiratory symptoms. Young animals carrying extremely large loads may have clogged intestines, which can result in colic and, in severe cases, death. Older horses who are impacted may have a poor hair coat, lose weight, or perform worse than usual.

Bloodworms(Strongylus vulgaris)

It is possible for bacteria to travel via the arteries surrounding the big intestine and induce colic. Historically, bloodworms were a significant concern in horses, but their prevalence and impact have diminished as a result of proper deworming.

Cyathostomins

These organisms live in the big intestine and migrate into the gut’s wall. Cyathostomins are known to produce severe gastrointestinal symptoms such as nausea, vomiting, and diarrhea. In this species, resistance to dewormers is rising, making targeted deworming even more critical

Pinworms(Oxyuris equi)

Horses less than two years old, as well as horses under inadequate supervision, are most susceptible. Despite the fact that worms dwell in the big intestine, they lay their eggs near the horse’s anus, causing the horse to scratch at its hind end. Due to the difficulty in treating and controlling pinworms, proper management of horses and pastures is essential

Tapeworms

Tapeworms are infrequent on the prairies, but the Anoplocephala perfoliata, which is the most prevalent tapeworm in Canada, is the most common tapeworm in the world. As a result of the fact that these worms spend part of their lives feeding on mites, they are difficult to eradicate
Yet, tapeworms do not appear to cause significant illness in horses. While colic is considered a possibility with this type of worm, the likelihood of experiencing it is extremely low.

Bots flies (Gasterophilus)

Bot flies deposit their eggs on the horse’s coat in the late summer and early fall, when the horse is most active. The eggs appear as minute yellow dots on the horses’ legs, with the majority of them being on the hind legs. During the course of licking or scratching their legs, horses consume bot egg larvae, which develop in the equine stomach and small intestine to become full-grown horses. Bots seldom produce clinical indications in horses, although they can cause gastrointestinal ulcers if the larvae are carried out through feces and hatch in the spring.

Consult with your veterinarian for recommendations on which exact products to use. Fenbendazole: This medication is effective against roundworms, bloodworms, and pinworms. Ivermectin: Ivermectin is effective against all parasites with the exception of tapeworms. Roundworms, on the other hand, have a high level of resistance to ivermectin. Ivermectin and praziquantel: These medications are effective against all parasites. Roundworms, on the other hand, have a high level of resistance to ivermectin.

Roundworms, on the other hand, have a high level of resistance to moxidectin.

Horse Worming Programmes

Horse worming programs that are tailored to the individual horse guarantee that specific worms are targeted with an effective treatment at the appropriate time. The following are the four major kinds of anthelmintics (horse wormers) available: 1.Benzimidazoles, such as fenbendazole and mebendazole, among others. 2.Tetrahydropyrimidines, such as pyrantel embonate (pyrantel embonate), 3.Macrocyclic lactones, such as ivermectins and avermectins, among others. Wormers based on the drug praziquantel (tapeworm treatment ONLY) Worming continuously throughout the year The importance of testing for and treating encysted small redworm in horses during the winter months cannot be overstated.

For this purpose, fenbendazole or moxidectin-based wormers can be employed, with the former being the preferred choice.

Spring and fall are the best times to perform this task, and either praziquantel or a pyrantel-based wormer should be used.

Your veterinarian or prescriber will be able to provide you with more information about this.

It is crucial to remember, however, that faecal egg counts are incapable of detecting encysted tiny redworm or tapeworm eggs, and that it is thus necessary to treat for these parasites at specific times of the year, as previously explained.

Worming a New Horse

A worming treatment or combination of products that will kill all forms and stages of roundworm (including encysted and inhibited tiny redworm) and tapeworm is recommended for each new horse that is brought into the household. If you worm your horse, you should keep him stable for 48 hours thereafter so that the wormer can take action and prevent viable eggs from being laid on the pasture.

Equine Deworming

Equines must be dewormed on a regular basis, and it is one of the least understood of the horse owner’s responsibilities. We are frequently asked questions such as “How often should I deworm?” and “How long should I deworm?” and “Can I deworm myself to the point of exhaustion?” We are fortunate to live in an environment that is friendly to parasites. For the most part, temperatures in the Willamette Valley do not reach temperatures high enough or low enough for long enough to kill parasites that lay their eggs in the dung of your horses.

However, the most crucial measure you can do is to adhere to a program that eliminates parasites from all of your horses, so interrupting the worm’s life cycle completely.

We propose that all horse owners, regardless of the size of their herd, implement a systematic deworming strategy to make this process easier and to alleviate any concerns you may have.

Here’s a quick outline of what you’ll need.
