How to Use the Llama Gestation Calculator
- Enter the date your llama was bred or exposed to a male.
- The calculator computes the expected due date based on 350-day llama gestation.
- Review the current gestation day and days remaining until birth.
- Check the developmental stage to understand fetal growth milestones.
- Plan cria (baby llama) preparations based on the gestation timeline.
The Formula
Variable Definitions
- Gestation: The period from conception to birth, averaging 350 days in llamas
- Cria: A baby llama or alpaca
- Dam: A female llama (mother)
- Sire: A male llama (father)
- Alpaca: A related but smaller camelid with similar gestation (335-350 days)
Calculating Llama Due Date from January Breeding
Find the due date for a llama bred on January 10, 2026.
- Step 1: Identify the breeding date: January 10, 2026.
- Step 2: Add 350 days gestation period to the breeding date.
- Step 3: Days remaining in January: 31 - 10 = 21 days. 350 - 21 = 329 days remaining.
- Step 4: Feb(28) + Mar(31) + Apr(30) + May(31) + Jun(30) + Jul(31) + Aug(31) + Sep(30) + Oct(31) + Nov(30) = 303 days. 329 - 303 = 26 days.
- Step 5: The estimated due date is December 26, 2026.

Frequently Asked Questions
How long is a llama pregnant in days?
A llama is pregnant for approximately 350 days (about 11.5 months). The normal range is 330 to 360 days. Alpacas have a slightly shorter gestation of 335-350 days. First-time mothers may go slightly longer.
How can I tell if my llama is pregnant?
Signs include: refusal to rebreed at the next heat cycle, slight belly enlargement after month 6, weight gain, and behavioral changes. Ultrasound can confirm pregnancy at day 17-20. Blood test for pregnancy-associated glycoprotein (PAG) at day 28-30.
How many crias will a llama have?
Llamas typically have one cria per pregnancy. Twins are rare (about 1 in 200 pregnancies) and can be dangerous. The gestation period is similar regardless of single or twin births, but twins may require assisted delivery.
When should I start preparing for the cria?
Begin preparing a clean, dry birthing area by day 300. Have a cria kit ready: towels, iodine solution, feeding tube, and scale. Monitor udder development 2-4 weeks before due date. Watch for behavioral changes indicating imminent birth.
What are signs of approaching labor in llamas?
Signs include: udder filling 2-4 weeks before, relaxation of the vulva 1-2 weeks before, behavioral changes (isolation, restlessness), and refusal to eat. Active labor begins with water bag appearance. Llamas usually give birth during the day.
How long does llama birth take?
Stage 1 (early labor): 1-2 hours. Stage 2 (active delivery): 20-45 minutes from water breaking to cria delivery. Stage 3 (placenta): 1-3 hours. If no progress after 30 minutes of active pushing, or if only one foot or head is visible, call your vet.
What should I do if the cria is not breathing?
Clear the cria's airway of mucus. Gently swing the cria by its hind legs (supporting the neck) to clear fluid. Rub vigorously with towels to stimulate breathing. If the cria still doesn't breathe, give a gentle puff of air into its nostrils. Call your vet immediately.
When does a cria start nursing?
A healthy cria should stand within 1-2 hours of birth and nurse within 2-3 hours. Colostrum intake is critical in the first 6 hours for immune system development. If the cria isn't nursing, you may need to tube-feed colostrum.
Can I breed my llama while nursing?
Yes, but it's not recommended. Breeding while nursing can drain the dam's body condition. Most breeders wait until the cria is weaned (3-6 months) before rebreeding. This gives the dam time to recover and ensures optimal nutrition for the next pregnancy.
