How to calculate your llama's due date
Llama gestation timeline — stage by stage
| Period | Stage | Key events & signs |
|---|---|---|
| Month 1 (Days 1–30) | Conception | Induced ovulation; embryo forms |
| Month 2 (Days 31–60) | Organogenesis | Organs develop; ultrasound confirms |
| Month 3 (Days 61–90) | Early fetal stage | Cria clearly visible on ultrasound |
| Month 4–6 (Days 91–180) | Steady growth | Maintain body condition |
| Month 7–9 (Days 181–270) | Rapid growth | Abdomen enlarges visibly |
| Month 10–11 (Days 271–330) | Final development | Parasite control; selenium check |
| Month 11–12 (Days 331–365) | Pre-birth | Udder development; cria movement visible |
Signs of parturition approaching:
- Belly enlargement from month 6
- Udder development 2–3 weeks before birth
- Cria movement visible from month 8
- Ligament relaxation near birth
- Increased restlessness and isolation
- Vulva elongation
Pre-parturition care checklist:
- Parasite control throughout pregnancy (fecal egg count based)
- Selenium supplementation in selenium-deficient regions
- Vitamin D important for indoor llamas
- Separate from males after pregnancy confirmed
- Cria born best at midday (llama naturally time birth)
