728x90 general

Parasites are very common to horses and there are about 150 of them that affect the overall health and wellness of a horse. The common parasites known to affect the horse are bots, strongyles, ascarids (roundworms), tapeworms and pinworms. The presence of these in your horse’s gut if left untreated may lead to nutritional deficiencies and problems that may even cause your horse’s death. This where Panacur Fenbendazole is widely used to eradicate these infectious parasites that may kill your horses. 

Thus, we take into great consideration to undergo a regular deworming treatment to ensure that we control the proliferation of these parasites in our horse’s body and maintain their health. Please seek the advice of your veterinarian before performing any deworming treatment to your horses to ensure proper medication and eradication of unwanted parasites.

This equine dewormer is often sold in packs of 5 as the manufacturer believes that deworming cannot be successful in one shot as others claim. This must be done in series to ensure that parasites have been well eliminated.

Panacur®is a powerful horse dewormer for use with horses, ponies, and foals. Manufactured by Merck. It has a gentle mode of action that is suitable to all horses in any size, age and body condition. It is also FDA approved and the only parasite medication for horses that treats ALL STAGES of the encysted small strongyle, and also treats ascarids which are just not a problem with young horses.

Panacur® is best for Ascarids.

This deworming medication is also popularly known as the best treatment option for ascarids, one of the most common and potentially grievous parasites in young horses and a growing problem in adult horses.

With the wide number of reports that claim the resistance of ascarids to macrocyclic lactones and pyrantel pamoate, which are both a common ingredient to some dewormer products. The larvicidal doses or what we call the ability of Panacur (fenbendazole) to act during the larval life-stage of parasites have been proven to effectively eradicate these ivermectin-resistant ascarids.

Safety with Panacur

The most important feature of any pharmaceutical product is its safety for use. Unlike any other deworming medications that have on their labels some written extreme warnings such as “Extreme caution should be used when administering the product to foals, young and miniature horses…Do not use on sick, debilitated or underweight animals.” And “This product should not be used in other animal species as severe adverse reactions, including fatalities in dogs, may result.” Panacur’s main ingredient, Fenbendazole has a proven record of safety profile and is safe for all horses no matter what age, size, weight, and body condition these horses have. There are also no known contraindication and its environment-friendly as well.  With its gentleness in its mode of targeting parasites, Fenbendazole may reduce the occurrence of side effects, such as endotoxic shock and impactions that typically occurs after deworming treatments in horses especially to foals with heavy roundworm infections.

Using Panacur® Medication and Deworming Treatment

Panacur treatment is recommended every year for;

  • Moderate-to-high strongyle egg shedders
  • Treating suspected parasite infection with horses suffering from recurrent colic and chronic weight loss, horses suffering from diarrhea and dehydration and other related known internal parasite infection in horses.
  • Arriving new horses before they are merged or combine with resident horses in the farm
  • Before you begin a daily dewormer, and once a year while continuing a daily deworming treatment
  • Prior to joining horse events or shows.

The severity of Deworming Treatment

Recommended Deworming Program (Sample Scheduling):

** January 1, March 1, May 1, July 1, September 1, November 1.

The two treatments that are in bold type are the recommended periods when the 5-day treatment regimen for the control of the migrating larvae of S. Vulgaris should be performed.

**For other areas in the world, retreatment periods for the migrating larvae of S. Vulgaris may be different; consult with your veterinarian.

In the case of the 4th Larval Stage of Strongylus Vulgaris, treatment and retreatment should be based on the life cycle and the epidemiology. Treatment should be initiated in the spring and repeated in the fall after a six-month interval.

Optimum Deworming Program for control of S. Vulgaris:

Optimum reduction of S. Vulgaris infections is achieved by reducing the infectivity of the pastures. When horses are running on pasture, in temperate North America, maximum pasture infectivity occurs in October-December. If horses are removed from those pastures in January, pasture infectivity will decline to zero by July 1. Egg production of S. Vulgaris is minimal from January through April, peaking in August and declining to minimal values in December.

***Always consult your equine veterinarian for the best results.

Understanding the Nature of Parasites Affecting Horses.

Here we will discuss the common parasites that greatly affect the health of horses, included is a description of what theses parasites are, where they came from, how they affect the horse, how they are treated and some advice on how to avoid the proliferation and infestation of these parasites in your horses.

  1. The Bots (BotFlies)
  • The Botfly looks like a honeybee, with light hair on the thorax and yellowish coloring.
  • The Larvae of the botfly is called a bot, and a horse infested with this is said to have bots.
  • The Botfly does not hurt the horse by its bites, rather, when they are many during the hot months of late summer, they start to lay eggs on the outer body of the horse.
  • The eggs are rounded, small, and usually yellow-orange in color.
  • The Botfly usually lays these eggs on the horse’s belly, inner legs and knees, and on the chin and nose. So when the horse licks these parts where the bots are a lodge, then the bots are now ingested into the horse body.
  • The bot has hooks on their mouth that make them lodge usually on the gastric lining of the stomach. But they stay for about 4 weeks in the horse mouth before they migrate into the digestive system and stay there for about eight to ten months until maturity.
  • As these parasites go out from the horse body through their manures, the emergence of botflies on the ground marks another cycle.
  • These parasites like a warm environment, so they are most common in states like Florida and other places where the weather is mostly warm and humid all year round.
  • There are three types of botflies:
    • The common horse bot which lays their eggs on the body and is ingested while the horse performs self-grooming.
    • The throat bot where eggs are laid on the neck part and beneath the jaw hence the larvae make their way into the horse’s mouth.
    • The nose bot which is rare and eggs are laid around the horse’s lips.
  • Symptoms of infection with bots:
    • Visible clumps of eggs (usually orange, yellow or cream in color) are present in the horse’s body particularly on the belly, inner legs and mouth.
    • Horse frequently rubs its face or bites objects in relief of irritation caused by these bots.
    • Ulceration in and around the mouth
    • Signs of abdominal pain and loss of appetite in horses.
  • Diagnosis may be done through a microscopic examination of the feces.
  1. The Strongyles
  • There are over 34 species of strongyles divided basically into 2 groups.
    • Large Strongyles are thought to be the most damaging among all the parasites in horses. Strongylus Vulgaris one of the four types of large strongyles was the most harmful worm in horses.
    • The Small strongyles have several names. One is scientific Cyathostomins. Another is non-migrating as they only burrow into the mucosal lining of the large intestine and become encysted there normally for 2-3 weeks, but may remain encysted and viable for 2.5 years.
  • Studies have indicated that 80%-90% of colic in horses is caused by strongyles both large and small groups.
  • The larva stages of large strongyles migrate throughout many tissues in the body of the horse such as liver, arteries, and intestinal lining.
  • The larvae of these parasites stay at the pile of manures until they reach their ineffective stage and migrate as high as 1.5 feet into the grass waiting for them to be eaten by the horse.
  • Once ingested, they travel into the intestines where they penetrate deeper into other tissues and organs like liver, kidney, lungs, heart, pancreas, arteries and etc.
  • The inflammation caused by this parasitic infection inside the body may lead to internal bleedings and clots into arteries and blocks blood flow thereby resulting in a possible death of a horse.
  • Then the larvae that develop into adults return to the intestines and lodge there to suck more blood that causes anemia to horses. Or the wormy horse syndrome and even death.
  • Symptoms of infection with strongyles:
    • Diarrhea and Dehydration
    • Sudden weight loss
    • Colic
    • Colon disruptions in absorption and digestion
    • Neutrophilia
    • Decreased level of albumin in the blood.
    • Increased level of globulins in blood fibrous cysts in the cecum
    • Rumbling bowel sounds
    • Intestinal Pain
  • Diagnosis may be done through a microscopic examination of the feces.
  1. The Ascarids
  • Also known as roundworms.
  • Mostly a common problem to foals but may also be carried out by adult horses.
  • The adult worms can be large as 40 cm in length.
  • The most common ascarid to infect horses is called Parascaris equorum.
  • The eggs laid by the large females pass out into pasture protected by a tough shell that equips them well for survival.  They can withstand drying conditions and even freezing; waiting for that moment when a passing horse ingests them with grass.
  • Once the larvae of this parasite are swallowed, they pass through the gut wall, via the liver to the lungs. Heavy infestations can cause coughing as the larvae travel through the lungs.
  • Ascarid can also cause intestinal impaction that leads to colic.
  • Symptoms of infection with ascarids:
    • Signs of respiratory distress
    • May have nasal discharges
    • Coughing
    • A possibility of fever
    • Weight loss
    • Poor coat complexion
    • Sluggish and pot-bellied appearance on the belly.
    • Colic Signs and Symptoms
  • Diagnosis may be done through a microscopic examination of the feces.

Prevention and Eradication of these parasites is a MUST by doing the following:

  1. Keeping the farm free from scattered manures. Regular cleaning and maintenance of the horse environment is very important to prevent the proliferation of these infective parasites. Also, spray on some insecticides when needed.
  2. Keep a regular horse grooming schedule or as needed to prevent your horse from licking itself for relief with irritations.
  3. Consult a veterinarian for deworming treatments and use of medications such as Panacur®. All horses are affected by these parasites and early detection of these may save you and your horse from a more serious problem in the future.
  4. Keep your food storage dry and clean and away from flies.
