Important Questions To Ask When Choosing Horse Supplements

In recent years, horse nutrition has been scientifically researched allowing for more targeted supplementation. A balanced equine diet must include fats, protein, carbohydrates, vitamins and minerals. Horses in heavy training, especially in humid, tropical climates, also require electrotypes. Commercially made feeds offer a good foundation but in many cases, additional health and nutritional support may be necessary.

Types of Equine Feed Additives

Additional vitamins, minerals and other essential ingredients can play an important part in keeping your horses fit and in optimal health. It’s important to understand the difference between the two types of supplements available:

Nutritional – vitamins, minerals, herbs and plant-based sources designed to enhance or balance your horse’s diet.

Health – provides support or maintenance of a body structure or function such as respiratory supplement

Are Supplements Safe?

When it comes to our horses, what we feed them is just as important as vet check ups and farrier visits. There are a lot of choices out there. Do your research. Read the ingredients list on the label. Typically, nutritional products made by or bought from reputable companies are safe provided you follow the instructions provided. Too much of certain ingredients can be unsafe, so it’s crucial to stick to the recommended dosage unless a veterinarian instructs you otherwise.

Do They Really Work?

When it comes to animal (or human) health, there is no magic pill. Horse owners, trainers and breeders are a well-informed audience so any company trying to market a feed supplement needs to show proof that their product works. Today, many equine products are backed by scientific research and case studies. If you aren’t sure if a company can support their product claims, contact them and ask for documentation if it’s not readily provided on their website. No facts? Then keep shopping.

Risk of Doping Test Failures

A positive swab before or after a race, show or competition can have major consequences. Testing positive can result in equine athletes and riders being suspended or disqualified. In some cases, winnings may be stripped. To avoid embarrassing and costly affirmative action, it’s crucial to find an equine health product that is truly free of any banned substances. TWYDIL® tests each product batch and is certified free of prohibited substances. Their supplements are FEI and RCI compliant for International competition, safe for use even on the day of the event.

Exercise-Induced Pulmonary Hemorrhage In Horses

EIPH or Exercise-induced pulmonary hemorrhage is common in Thoroughbreds and Standardbreds, especially those that race. It is bleeding, or epistaxis, from the nasal passages following extreme exertion. The bleeding may be accompanied by loud breathing, choking or excessive swallowing. According to Wag!, equines that suffer from bleeding airways may also show signs of distress. [1]

What Causes Equine Bleeding Attacks?

Possible causes include high lung blood pressures during intense exercise, lung inflammation, and shear forces within the chest generated during exercise. Research is ongoing, and the condition is likely due to multiple factors. – Merck Veterinary Manual. [2] Finding lesions in the lungs of EIPH horses may indicate that this condition is a disease rather than a result of extreme exercise. The possibility of it being a progressive disease is there but again, more research is needed for confirmation.[3]

Are Racehorses the Only Equines That Bleed After Running?

EIPH is a condition commonly found in the racing industry, however, bleeders can be found in other equine sports. Disciplines that require short but strenuous exertion such as polo, show jumping, barrel racing and eventing can also rupture the capillaries in the lungs releasing blood into the airways.

Veterinary Diagnosis Options

Not all equines will have bloody noses or blood-tinged mucus that drips from one of both nostrils. When the vet scopes your horse, they may only find blood within the lungs or airways. Only proper examination can determine if the bleeding is caused by exercise-induced pulmonary hemorrhage or another condition. Diagnostic tools helpful for confirming the cause of bleeding in equine lungs and airways: Endoscopic exam – Camera passed through the nose into the airways immediately after exercise Bronchial-alveolar lavage (BAL) fluid examination – Saline wash of the airways and air sacs to collect a fluid sample Trans-tracheal wash (TTW) fluid examination: An aseptic airway wash to collect fluids for in-depth cytological, culture and sensitivity testing. (done under sedation) Radiography, pulmonary scintigraphy and lung function tests – Used to eliminate other respiratory conditions that may be causing poor performance[4]

Recommended Treatment

Once a proper diagnosis is made, your veterinarian will decide what medication, if any, is needed for your bleeder. Medications such as furosemide, bronchodilators and corticosteroids may reduce the severity of the hemorrhagic episodes but may not stop the bleeding completely. [5] Complete recovery from a bleeding episode may take four to six weeks. In many states and countries a horse cannot race for at least 10 days after a bleeding episode. – EquiMed [6]

Having a horse come out of the ring or off the track with a bloody nose can be unsettling. While we can’t cure EIPH, TWYDIL USA does offer a respiratory supplement intended to minimize oxidative stress and reduce inflammation. TWYDIL X is a proprietary formula created to provide essential support to the lungs and blood vessels. It helps reduce airway bleeding and promotes the recovery of lungs damaged by EIPH related episodes.

The Best Calming Supplements for Horses

Even the best trained horses can experience anxiety and nervousness occasionally. Some situations, like shipping or having their teeth done can stress out even the quietest of equines. Maybe your favorite mount is just a little high strung. Having a calming aid in your feedroom that you know works quickly and safely for all horses is a gift to horse owners.

Ingredients That Help Relax Nervousness

Finding a horse calming supplement that is both safe and effective takes a little homework. You’ll want to skip any calming agents that use a drug to relax your horse. Calming is not the same as sedation. Not only can drugging your horse cause him to lose focus, but it’s dangerous, habit-forming and against competition rules. Make sure to carefully read the label. Look for all-natural, soothing ingredients such as L-Tryptophan, Magnesium and Vitamin B.

How Does Tryptophan Work to Calm Horses?

Serotonin is a neurotransmitter in the equine brain that helps lower the level of fear, stress and anxiety that horses may experience. It has a mild sedating effect that is achieved without drugs. The amino acid, L-Tryptophan, is a building block of serotonin. Horses that lack tryptophan often exhibit anxiety, nervousness and spook easily. This naturally occurring ingredient is used in supplements to produce quieter behavior in horses.

Benefits of Magnesium Proteinate

Magnesium is a key ingredient in most calming supplements because it’s known to help horses that tend to be excitable and jumpy. Stress can cause their magnesium levels to drop. Equines that have a magnesium deficiency may act anxious and jittery. Magnesium Proteinate is a chelated trace mineral with a high degree of bioavailability meaning the body can absorb more of it rather than waste it. For equine athletes, magnesium can have a performance boosting effect as it increases oxygen delivery to muscles and helps the body metabolize carbohydrates and aminos for all day stamina.

Vitamin B in Equine Mood Supplements

The same B vitamins that are known for having anti-anxiety effects on people can also help horses to relax. B Vitamins are commonly used for performance horses to ease the stress of travel and competition. Thiamine or B1 is often sold alone for its calming and relaxing effects on scared or easily excited horses.

The Horse Calmer That Actually Works

When you find yourself with a nervous horse that spooks or gets stressed out easily, TWYDIL USA has the calming solution that professional trainers, breeders and competitors rely on. This is not just a quick fix to get your horse through an unpleasant situation. TWYDIL® C is a sedative-free supplement that soothes anxious horses, promotes quiet behavior and enhances performance. Because it calms naturally, it allows horses to remain relaxed yet focused throughout the entire day of competition. TWYDIL® C also meets all strict international anti-doping requirements and is safe for use in horses of all ages.
