Why We Use the TRH Stimulation Test for PPID Detection …. And Why This Matters

Recurrent or unexplained laminitis especially in older horses is usually a red flag for an underlying endocrine disorder. While Equine Metabolic Syndrome (EMS) is a well-known cause of insulin dysregulation and laminitis, another common culprit in ageing horses is Pituitary Pars Intermedia Dysfunction (PPID).

Pituitary Pars Intermedia Dysfunction (PPID): often still mistakenly referred to as “Cushing’s Disease” is one of the most common endocrine disorders affecting older horses and ponies. While the terms are sometimes used interchangeably, true “Cushing’s disease” (seen in humans and dogs) is a very different condition. In horses, PPID is caused by degeneration of specific neurons in the brain that normally regulate the pituitary gland. This leads to overproduction of hormones, including ACTH (adrenocorticotropic hormone), and results in a range of clinical signs including abnormal coat shedding, loss of muscle over the topline, lethargy, increased drinking and urination, susceptibility to infections, and an increased risk of laminitis.

At this time of year we often recommend the TRH stimulation test in selected horses. This test is more sensitive than a baseline ACTH test, particularly for detecting early or subtle cases of PPID. It involves measuring the ACTH response following administration of a hormone (TRH) that stimulates the pituitary. It can help confirm PPID in horses that don’t show the classic signs, but might be failing to respond to appropriate EMS management.

Careful case selection and timing of the test is essential. We do not recommend testing horses for PPID when they are actively laminitic or in severe pain. Pain and stress (and even transport to a clinic!) can falsely elevate ACTH levels, leading to inaccurate results and unnecessary treatment. Testing should be delayed until the horse is clinically stable.

It’s also important to understand that while hyperinsulinemia (high blood insulin) in EMS horses is a common cause of laminitis in younger horses and ponies, older horses with recurrent laminitis episodes despite correct EMS management should be assessed for underlying PPID. In these cases, persistent or worsening laminitis may be the result of an undiagnosed or poorly managed pituitary disorder, rather than insulin dysregulation alone.

PPID and EMS often overlap, and managing one without recognising the presence of the other can lead to treatment failure or recurrence of laminitis.

****The choice of test AND interpretation of results MUST be guided by a veterinarian experienced in both EMS and PPID.

****Misdiagnosis or inappropriate treatment and management recommendations may delay recovery and increase the risk of long-term complications.

If your horse is older and struggling with unexplained laminitis, get in touch to discuss whether TRH stimulation testing may be appropriate. Early and accurate diagnosis is key to improving quality of life and reducing the risk of further episodes.

🐎 Confused about worming your horse? You’re not alone.

Worming advice can feel overwhelming. F***l egg counts, resistance, pasture hygiene… it’s a lot of jargon, and much of the old advice is now outdated.

That’s why I’ve created a FREE Worming Mini-Course for Horse Owners, based on recently published Australian guidelines and current veterinary recommendations.

✅ Clear, easy-to-follow lessons
✅ Explains why we do things, not just what to do
✅ Breaks down the science into practical, real-world advice
✅ Helps you worm smarter, not more often

This mini-course will help you:
• Reduce unnecessary drenching
• Protect dewormers from resistance
• Build a targeted, horse-specific worming plan

📩 Delivered straight to your inbox

If you’ve ever thought “I’m just doing what I was told years ago” 👉 this course is for you.

A dull donkey is a sick donkey 🫏

Donkeys are masters at masking pain — not because they don’t feel it, but because, as prey animals, showing weakness is dangerous. Remaining quiet and outwardly “normal” is a survival strategy. Unfortunately, this means that illness and pain in donkeys are often recognised late.

In donkeys, the slightest change in behaviour can signal compromised health. Learning to read the donkey is one of the most valuable skills an owner can develop. Subtle cues in ear position, eye expression, nostrils, head and neck carriage, body tension, and tail movement can be far more informative than dramatic signs. A donkey that looks flat, withdrawn, or simply different from their usual self deserves close attention.

Time spent lying down is particularly important. Donkeys normally rest in short bouts, so a donkey lying down for prolonged periods, especially when combined with reduced food intake, should raise concern. Superficial skin lesions or scuff marks from thrashing while recumbent can also indicate discomfort or pain, even if the donkey is quiet when you approach.

Colic can be especially difficult to recognise in donkeys. They may not roll or paw like horses. Instead, pain may show up as a facial grimace — changes in ear position, head and neck posture, and a tense or altered facial expression. These signs are easy to miss unless you’re actively looking for them.

Similarly, donkeys and mules often show minimal response to hoof testers, even with significant foot pain. This is why lameness and laminitis can be underestimated, and why diagnostic tools such as radiography and ultrasound are often needed to fully assess the problem.

Physiologic differences also matter. Donkey heart rates are generally higher than horses, and resting values in donkeys and mules often sit in the mid-40s beats per minute. Interpreting vital signs without recognising these species differences can lead to false reassurance.

The key takeaway is simple but critical: a dull donkey is never normal. If your donkey is quieter, less interactive, eating differently, or just “not quite right,” early veterinary assessment can be lifesaving. With donkeys, waiting for obvious signs often means waiting too long.

🌾 Mycotoxins: The Invisible Feed Toxin Many Owners Don’t See Coming

Not all toxicities in horses come from plants growing in paddocks.

Mycotoxins are toxic compounds produced by certain moulds that grow on hay, chaff, grains, and mixed feeds, particularly when conditions are warm or damp — especially in hay kept in hay rings and huts where moisture can still pe*****te.

Mycotoxins primarily damage the liver. Horses exposed to aflatoxins may show vague, non-specific signs such as weight loss, lethargy, poor appetite, reduced performance, or increased susceptibility to infections. In more severe cases, signs of liver dysfunction may develop.

Multiple horses may be affected at the same time if they are eating from the same contaminated feed source, which can be an important clue. Importantly, mycotoxins are not destroyed by drying, storage, or mixing feed, and feeding “around” mouldy sections is unsafe.

Management relies on early recognition, immediate removal of the feed source, and supportive veterinary care.

Feed-related toxicities like mycotoxins are a key part of our free Poisonous Plants Mini-Course for WA horse owners, where we explain what to watch for and how to reduce risk.
