Llama pregnancy guide

How long is a llama pregnant?

A llama is pregnant for about 350 days (about 11.5 months). The normal range is 330 to 370 days, so most cria arrive within that window rather than on the exact average day.

Quick rule: Count about 11.5 months forward from the mating date, then adjust for breed.
