Llama Gestation Period: How Long Is a Llama Pregnant?

A llama is pregnant for about 350 days, roughly 11 months and 2 weeks. Normal birthing happens between 330 and 365 days, and a typical litter is 1 cria.

How long is a llama pregnant?

A llama carries her cria for an average of 350 days, or about 11 months and 2 weeks. Counting from the breeding date, birthing is normal anywhere from day 330 to day 365.

Key checkpoints across the 350-day llama gestation, measured in days from breeding:

Llama gestation timeline from day 0 to day 350: day 14 Spit-off test to screen for pregnancy; day 45 Ultrasound or blood test confirms the pregnancy; day 90 Recheck for early embryo loss; day 250 Clostridial booster ahead of birthing; day 305 Increase the ration; shear if she is due in hot weather; day 330 Earliest normal birthing — begin daily morning checks; day 350 Expected birthing.

Llama gestation stages, month by month

Days 1–90: early pregnancy

Confirm with a spit-off at two weeks and ultrasound from about day 45, then recheck around day 90 because early loss is common. No extra feed is needed. Avoid moving her between herds, which is a common cause of stress-related loss in camelids.

Days 91–220: mid pregnancy

Maintenance feeding on good forage plus a camelid mineral supplement is sufficient. Keep her lean rather than fat; obesity is the leading manageable cause of difficult births in llamas. Handle feet, teeth and vaccinations in this quiet window.

Days 221–310: late pregnancy

The cria gains most of its birth weight. Lift energy and protein gradually, provide shade and shearing if she is due in summer, and give clostridial boosters about six weeks out so colostrum protects the cria.

Days 311–365: birthing window

Check her every morning. She will separate a little, make frequent unproductive trips to the dung pile, hum and become restless. Nose and both forelegs should appear together. The cria should stand and nurse within two to three hours and receive colostrum promptly.

Signs a llama is pregnant

She spits at and refuses the male from around two weeks after mating
Ultrasound or a blood test confirms pregnancy from about day 45
The left flank fills out and cria movement becomes visible in the last two months
Udder development in the final month to six weeks

Signs of approaching birthing

Frequent trips to the dung pile, humming and mild separation from the herd on the day
Rolling, tail raising and visible straining in the final half hour, nearly always in daylight
Contact your vet if labour stalls, if the animal strains without progress, or if there is abnormal discharge before birthing begins.

What affects llama gestation length

Llamas carry slightly longer than alpacas — about 350 days against 345 — and the normal range of 330 to 365 days is wide enough that a fortnight either side of the calculated date is unremarkable.
Like alpacas, llamas are induced ovulators with no oestrous cycle, so mating triggers ovulation and the breeding date is usually known to the day.
Nearly all pregnancies sit in the left uterine horn, and twins are so rare that a twin pregnancy is a veterinary problem rather than a bonus.
Llamas also give birth in daylight, typically morning to early afternoon, and a normal delivery is quick — often under 30 minutes of active straining.
Crias are born without the ability to absorb antibodies for long: colostrum in the first six hours decides whether the cria has working immunity.

Llama pregnancy FAQs

How long is a llama pregnant?

About 350 days — roughly 11 and a half months — with a normal range of 330 to 365 days. Llamas carry marginally longer than alpacas, so do not use an alpaca due date for a llama.

How is a llama pregnancy confirmed?

A spit-off test at about 14 days gives a first indication, and ultrasound or a progesterone blood test from around day 45 confirms it. A recheck near day 90 is worth doing because early embryonic loss is common in camelids.

How much extra feed does a pregnant llama need?

Very little until the last third. Good forage and a camelid-specific mineral supplement covers most of the pregnancy; over-conditioning her causes birthing problems. Increase energy and protein modestly in the final two to three months.

What does a normal llama birth look like?

Fast and in daylight. Once straining starts, the nose and both front feet appear and the cria is usually delivered within 30 minutes. She gives birth standing, so the cria drops a short distance — that is normal and helps clear the airway.

What should I do in the first hours after the cria is born?

Dip the navel in iodine, check the cria is up and nursing within two to three hours, and make sure it gets colostrum within the first six hours. Weigh it if you can: a cria that loses weight over the first two days is not getting enough milk.
