🦴 Did you know that horses have 205 bones, just one less than adult humans, who have 206? Some breeds, like the Arabian, may have even fewer!

🦷✨ Ever wondered how we keep our equine friends healthy and pain-free? Today, we're taking you behind the scenes of a successful oral tooth extraction!

Oral health is just as important for horses as it is for us. When a tooth becomes infected or damaged, it can cause significant discomfort and lead to more severe health issues such as sinusitis. That’s where our expert team steps in!

With the help of Professor Steenkamp, our surgeons carefully removed a diseased tooth to relieve the horse's pain and prevent further complications. With the use of specialized tools and techniques, we ensured the process was as smooth and stress-free as possible for our patient. This horse will be feeling much better in no time, thanks to the dedicated care from our team! 🐴💪

Regular dental check-ups are key to maintaining your horse's overall health. If you notice any signs of discomfort, changes in eating habits or nasal discharge, don't hesitate to consult with us. We're here to ensure your horse enjoys a long, healthy life!

Horses graze up to 17 hours a day! – horses are grazing animals and spend most of their time searching for food – due to their physiology they have to take in food constantly in small amounts, thus it is vital that horses are given ad libitum roughage (such as hay) or possibility to graze so that they do not develop any gastrointestinal dysfunction!

Can you get all 17 labels? Watch our stories daily for the answers. We're starting today at noon 😁

Granulosa cell tumours (GCT) are the most common ovarian tumour in horses and can occur in mares of any age. They may be composed of granulosa cells alone or contain theca cells. These tumours are almost always unilateral, functional, and benign.

The hormonal pattern of GCTs is inconsistent, resulting in a variety of clinical signs. Persistent, irregular, or absence of oestrus. Stallion-like behaviour e.g. mounting, aggressiveness, squealing, striking. In chronic cases, increased muscle deposition, a cresty neck, and an enlarged cl****is.

Typically, one o***y is enlarged with no palpable ovulation fossa. GCTs are slow-growing tumours but can reach up to 40 cm in diameter. The contralateral o***y is usually small, firm, and inactive.

GCT often have a multicystic honeycomb appearance on altrasound. Some may present a dense homogeneous appearance or appear as a solid ovarian mass with a single anechoic fluid-filled cyst. Haematomas or regions of necrosis within the tumour are common.

Since clinical signs, re**al examination findings, and ultrasonographic appearance are not consistently reliable in predicting the presence of a GCT, measuring serum hormone concentrations is recommended for diagnosis.

Serum levels of anti-Müllerian hormone (AMH) have recently been shown to be a reliable means of identifying GCT in mares. In a recent investigation, the diagnostic accuracy of AMH, inhibin, and testosterone for diagnosing GCT was compared in 44 mares with histopathologically confirmed GCTs. The sensitivity of AMH for detecting known GCTs was 98%, compared to 80% for inhibin, 48% for testosterone, and 84% for the combination of inhibin and testosterone (Ball et al., 2013).

The treatment for GCT is surgical removal of the affected o***y. Standing laparoscopic surgery through the paralumbar fossa can be considered depending on the mare’s temperament. Most mares return to normal oestrous cycles within 6-8 months following unilateral ovariectomy, with a range of 2-16 months. Fertility usually returns to presurgical status after oestrous cycles have been re-established.

Here you can see a recent case undergoing unilateral laparoscopic ovariectomy.

A 2024 census revealed there are approximately 330,000 horses in South Africa.
This includes rural horses, but excludes other equids (donkeys, mules, zebra). This is up from 280,000 in 2004.

There are an estimated 60 million horses in the world, combining wild and domesticated horses.

We love working to keep them all happy and healthy.

Are you ready for emergency travel?

“Emergencies are nerve-racking enough, but not having easy access to a truck and trailer or having a horse that won't load can make an already stressful situation a lot worse.” ~AAEP

Make sure your horse knows how to box even in stressful situations. Practice regularly (even at night).

While a variety of things can contribute to the development of stomach ulcers (medications, diet, stress, etc.), one train of thought is that these areas of irritation result as a consequence of the acid of the stomach splashing against unprotected parts of the stomach lining. When a horse eats forage, the hay can help absorb some of that acid and thus reduce the risk of ulcer formation.

It is important to note that a forage meal (one comprised of hay or grass) provides the most benefit, while eating large volumes of concentrate feeds (such as oats, corn, or other cereal grains) can actually increase the amount of acid within the stomach.

As always, please consult with your vet regarding further diagnostics and treatments if you have concerns that your horse may have gastric ulcers.

Small Redworms alert! 🐴🪱

Did you know the recommendations for worming horses have evolved? Stay informed to keep your horses healthy! Recently, we identified small redworms (Cyathostomins) in a horse’s colon during laparotomy.

During winter, Cyathostomin larvae hibernate in the gut wall, encysting there until the warmer spring months. When they emerge, they can cause significant intestinal wall damage, leading to sudden weight loss, abnormal blood conditions, diarrhoea, colic, and even sudden death.

Appropriate (and well-targeted) winter treatment is crucial! Moxidectin and praziquantel combined can target small redworms, other roundworms, bots, and tapeworms. Always discuss the best protocol with your vet.

With increasing resistance to anthelmintics, a targeted and responsible worming strategy is vital. At Onderstepoort, we offer multiple tests to make worming as specific, and cost-effective as possible. For more advice, speak with your vet on the best approach to test and treat your horse.

- Weekdays: 3:00 PM - 5:00 PM
- Weekends & Public Holidays: 9:00 AM - 11:00 AM

If your horse's condition allows it, we will happily let you take them for a walk and graze outside. We try our best to be available during visiting hours which allows us to spend time explaining any unanswered questions you may have.

The peroneus tertius originates with the long digital extensor muscle from the extensor fossa of the lateral femoral condyle and inserts on the third tarsal bone, third metatarsal bone, fourth tarsal bone and calcaneus. The PT flexes the hock when the stifle is flexed.

Complete or partial rupture of the tendon usually occurs due to over-extension trauma. A classic example is a horse in a full hindlimb cast that slips and falls. Other causes of blunt trauma can include falling down or a hindlimb caught in bars.

A characteristic gait is noted when the horse walks: the stifle flexes but the hock extends. Or passively, the hock moves independently from the stifle.

Ultrasound and radiography are useful in the diagnosis especially to assess associated structures or concurrent fractures. The larger the percentage of ruptured fibres, the less likely the horse will return to their intended use. The degree of lameness at presentation does not have an influence on the outcome.

Prognosis is correlated to the location and degree of rupture. The prognosis is better when the tibial region is affected compared to the origin of the PT at the lateral femoral condyle. The outcome is greatly influenced by the involvement of other soft tissue structures.

Treatment is conservative and involves 3-4 months of box rest ± hand-walking depending on lameness and US findings. US should be used to evaluate healing and adjust the rehab program.

Questions:
1. Which structure is most likely damaged in this pony?
2. What is its function?
3. How does this injury normally occur?
4. What are your treatment options?
5. What prognosis can you give to the owner?

Answers:
1. Peroneus Tertius
2. Part of the reciprocal apparatus of the hind limb (concurrent flexion and extension of the hock and stifle)
3. Hyperextension of the hind limb
4. Conservative treatment with 3-4 months of stall rest and then gradual reintroduction of exercise can result in complete resolution and return to athletic activity.
5. Good to poor depending on the location of rupture. Reported good prognosis for ruptures in the tibial region and poor if rupture occurs at the point of origin from the femur.
