Typical Llama Gestation Example
Camelid type: Llama
Mating date: January 15, 2025
Gestation period: 342 days (11-12 months)
Expected birth date: December 23, 2025
Birth window: December 13, 2025 - January 2, 2026
Expected offspring: 1 cria (twins are rare)
Calculation
Birth Date = Mating Date + 342 days
Birth Date = January 15 + 342 days
Birth Date = December 23, 2025
Normal Range: 332-352 days
Earliest Birth: December 13, 2025 (332 days)
Latest Birth: January 2, 2026 (352 days)

Understanding Llama & Alpaca Gestation
Camelid Gestation Period
Both llamas and alpacas have an average gestation period of 342 days (about 11-12 months), making them one of the longest gestation periods among domestic animals. The normal range is 332-352 days, and most births occur during daylight hours.
Mating Behavior
- •Females adopt "cushing" position when receptive
- •Stop being receptive 15 days after successful mating
- •Implantation occurs around day 30
- •Gestation detectable via ultrasound at 34 days
Llama vs Alpaca
Llamas
Larger (80kg breeding weight), thick wool, used for guarding and fiber
Alpacas
Smaller (40kg breeding weight), fine hypoallergenic fiber, premium textile use
Birth & Offspring
Camelids typically give birth to one cria (baby). Twins are extremely rare. Labor can last up to 12.5 hours, and most births occur during daylight hours.
Nutrition Tip: During gestation, supplement regular diet with small amounts of alfalfa for added protein, vitamins, and minerals.
