🚀 Quick Summary
- The Difference: Donkeys/Minis are Desert Animals. They evolved to survive on scrub.
- The Risk 1 (Obesity): “Lush Pasture” is poisonous to them. (Laminitis/Founder).
- The Risk 2 (Ulcers): Despite being fat, they get ulcers easily from stress/NSAIDs because they metabolize drugs faster.
- The Killer: Hyperlipemia (Fatty Liver). Triggered by stress or fasting (e.g., for a scope prep).

1. Donkey Physiology: Why They Are Aliens
Donkeys are not small horses.
- Metabolism: Extremely efficient. Gain weight on air.
- Stoicism: They hide pain 10x better than horses. A donkey with a twisted gut might just stand quietly until it dies.
- Drug Clearance: They often clear drugs (NSAIDs/Sedatives) faster. Dosing can be tricky.
2. Hyperlipemia: The Fasting Trap
In horses, if they stop eating for 2 days, they lose weight. In Donkeys/Minis, if they stop eating for 12-24 hours, the body panics.
- Mechanism: Mobilizes massive amounts of fat into the bloodstream to fuel the brain.
- Liver: The liver gets overwhelmed by fat -> Fatty Liver Failure.
- Result: Death (Mortality > 60%).
- Trigger: Pain (Colic/Ulcers), Stress (Weaning/Transport), or Fasting for a Scope.
Rule: NEVER fast a mini/donkey for > 6 hours without vet supervision.
3. Ulcer Symptoms: The Stoic Patient
Don’t look for girthiness or drama. Look for:
- “Dullness”: Just standing head low. Not engaging.
- Off Feed: Refusing a favorite treat.
- Lying Down: More than usual.
- Sham Eating: Picking at food but not swallowing.
If a donkey refuses food, assume it is Serious.
4. Treatment Dosage: Higher than Horses?
Studies differ, but generally:
- Omeprazole: Donkeys may require slightly higher doses (up to 6 mg/kg) or twice-daily dosing because they metabolize it faster.
- NSAIDs (Safe?): Donkeys are highly sensitive to NSAID toxicity (Kidneys). Use Firocoxib (Equioxx) or half-doses of Banamine.
5. Diet: How to Feed a Fat Ulcer Case
The Dilemma: He has ulcers (needs constant food) but is obese (needs diet). Solution: Straw.
- Barley Straw / Oat Straw: Very low calorie, high fiber.
- Strategy: Feed 75% Straw + 25% Grass Hay in a Slow Feeder Net.
- Result: He chews 24/7 (Buffers stomach) but doesn’t get fat.
- Supplements: Vitamin/Mineral Balancer (Low Calorie) + Psyllium (if on dirt).
6. FAQ: Can they have Alfalfa?
Q: Is Alfalfa safe for minis? A: As a treat/buffer ONLY. Alfalfa is too high calorie for a staple diet. However, giving a handful (1/4 flake) before an event or trailer ride provides excellent calcium buffering without blowing up the waistline.
🏆 Final Verdict
Treating a mini is walking a tightrope between Ulcers (Empty Stomach) and Hyperlipemia (Starvation).
- Keep food in front of them (Straw/Slow Feeder).
- Monitor intake constantly.
- Avoid NSAIDs.
- Call the Vet EARLY. A dull mini at 8 AM can be in liver failure by 8 PM.
