How the calculator works It adds the gestation length to the date you enter, counting calendar days (including leap days). The default for alpaca & llama is 346 days, and the result also shows a window of 339 to 353 days (middle half of pregnancies). Middle half of 7,049 alpaca pregnancies; the full observed range was 270 to 428 days. Change the length if your vet, breed society or sire information says otherwise. All calculations run in your browser; nothing you enter is sent anywhere.
Worked examples An alpaca mated on November 1, 2026, has a median due date of October 13, 2027 , with half of births falling between October 6 and October 20. Alpaca & Llama gestation facts Alpaca (median) 346 days; middle 50% 339 to 353 Llama About 11.5 months (~350 days)
Common questions Why is the range so wide? A 2025 study of 7,049 alpaca pregnancies worldwide found lengths from 270 to 428 days. Season, location, sire and dam all play a part.
Do alpacas have a heat cycle? Alpacas and llamas are induced ovulators, so the calculator does not show return-to-heat dates for them.
