Hay and pasture rarely supply every mineral and vitamin an alpaca needs. A good camelid-specific loose mineral fills the gaps — and choosing the wrong product can cause deficiency or toxicity.
Why “camelid-specific”?
- Sheep minerals contain little or no copper because sheep are copper-sensitive. Fed long term, they can leave alpacas short on copper.
- Cattle and goat minerals may contain too much copper for camelids and sometimes ionophores (monensin) that are toxic to camelids.
- Camelid formulas balance selenium, zinc, copper, vitamin E and vitamin D for alpacas.
Offer minerals loose in a covered feeder, free choice. Alpacas’ soft tongues can’t lick hard blocks well, and biting blocks can break teeth.
Key nutrients
| Nutrient | Why it matters | Notes |
|---|---|---|
| Selenium & vitamin E | Muscle, immunity, fertility | Many regions are low; deficiency causes white muscle disease. Selenium has a narrow safety margin — don’t stack products. |
| Vitamin D | Bone growth | Crias and juveniles in northern latitudes need winter supplementation to prevent rickets. |
| Zinc | Skin and fiber | Low zinc is linked to zinc-responsive dermatosis. |
| Copper | Fleece pigment, blood | Both deficiency and toxicity occur. |
| Calcium & phosphorus | Bones, milk, urinary health | Keep Ca:P about 1.2–2:1; high phosphorus feeds raise urinary stone risk. |
| Salt | Water intake | Usually in the mineral mix; encourages drinking. |
| Iodine | Thyroid | Supplied by mineral; avoid excess kelp. |
Selenium by region
Large parts of North America have selenium-poor soils — the Pacific Northwest, the Great Lakes, the Northeast and much of the Atlantic Southeast — while parts of the Great Plains are adequate or high. Each of our state and county guides shows the local selenium status. Ask your vet to blood-test a few animals before changing supplements.
Vitamin D for crias
At latitudes above about 35–40°, UVB from winter sunlight is too weak for vitamin D synthesis. Many vets recommend vitamin D for crias and young stock every 1–2 months from autumn to spring. Your county guide lists the recommended months.
Other supplements
- Camelid pellets supply minerals plus protein for breeding stock.
- Black oil sunflower seeds (BOSS) — 1–2 tablespoons a day for fleece condition and vitamin E. See BOSS.
- Probiotics — sometimes used after illness or antibiotics; evidence is limited.
- Electrolytes — useful in heat waves and for sick animals.
Supplements to avoid or question
- Garlic and “natural dewormers” — no proven benefit and garlic can cause anemia.
- Extra copper boluses without liver testing.
- Multiple selenium products at once.
- Medicated cattle or poultry feeds.
Frequently asked questions
Can alpacas use horse or sheep mineral? Not as a long-term substitute. Use a camelid-specific mineral.
Do alpacas need salt blocks? Loose mineral with salt is better than blocks.
