Why it matters

Garden lupines and western range lupines are both risky, particularly in late summer when seed pods are present.

Signs of lupine poisoning in alpacas

  • Nervousness, trembling, staggering
  • Labored breathing
  • Birth defects (crooked limbs) if eaten in early pregnancy

Signs can appear within minutes (cyanide, cardiac toxins) or only after weeks of exposure (liver toxins). Many poisoned camelids are simply found dead, so prevention is everything.

What to do if your alpaca ate lupine

  1. Move the herd away and remove any remaining plant material, clippings or fallen leaves.
  2. Call your veterinarian immediately, even if the alpaca looks normal. Say what was eaten, roughly how much and when.
  3. Bring a sample or clear photo of the plant to help identification.
  4. Do not give home remedies, oils or try to make the alpaca vomit unless your vet tells you to.
  5. Keep the animal quiet, in shade or shelter, with water available. Write down the time and every symptom you see.
  6. Check every other alpaca that had access, then remove the plant permanently (including roots).

Emergency: call your veterinarian immediately. If you cannot reach them, contact an animal poison control service (in the U.S., the ASPCA Animal Poison Control Center or Pet Poison Helpline; fees may apply). Bring a sample or photo of the plant.

About the plant

Lupinus, commonly known as lupin, lupine, or regionally bluebonnet, is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centres of diversity in North and South America. Smaller centres occur in North Africa and the Mediterranean. They are widely cultivated both as a food source and as ornamental plants, but are invasive to some areas. For instance, lupine has become an ecological problem in Iceland since the beginning of the 21st century.From Wikipedia — “Lupinus”, licensed under CC BY-SA 4.0.

Frequently asked questions

Is lupine poisonous to alpacas?
Yes. Yes — lupine is toxic to alpacas. Garden lupines and western range lupines are both risky, particularly in late summer when seed pods are present.
What part of lupine is toxic to alpacas?
Leaves, pods and especially seeds.
What are the symptoms of lupine poisoning?
Nervousness, trembling, staggering, labored breathing and birth defects (crooked limbs) if eaten in early pregnancy.
Is dried lupine safe?
Drying does not reliably make poisonous plants safe. Treat dried leaves and contaminated hay with the same caution.

Keeping pastures safe

  • Walk every paddock and fence line each season and remove toxic plants, including roots.
  • Never throw garden, hedge or lawn clippings over the fence.
  • Check pastures after storms for fallen branches (cherry, red maple).
  • Buy hay from known sources and inspect it for weeds.
  • Keep pastures well managed — hungry alpacas eat plants they would normally avoid.
