    About the numbers

    For alpacas we use 346 days. It is the middle of 7,049 pregnancies from 2002 to 2024 (Ponthier and others, 2025). Half the crias came between day 339 and day 353. Rutgers gives 335 days.

    For llamas, UC San Diego gives 342 to 355 days. We use the middle, 348.5 days. Rutgers says 350.

    Questions

    How long is an alpaca pregnant?

    About 346 days, a little over 11 months. In a study of 7,049 alpaca births, half came between 339 and 353 days.

    How long is a llama pregnant?

    About 350 days, says Rutgers. UC San Diego gives 342 to 355 days.

    Why do some charts say 335 days for alpacas?

    Rutgers gives an average of 335 days. The 2025 study of 7,049 births found 346. We use 346, from the bigger count.

    Do alpacas and llamas have a heat cycle?

    No. They release an egg when they are bred, says Rutgers. So we do not show days to watch for heat.

    How far off can the date be?

    In the alpaca study, births came from 270 to 428 days. Very early or very late ones are rare. Ask your vet if she goes long.
