Pregnancy Guide for Guinea Pigs

Cute Guinea Pig

A pregnant mom always needs special care, Guinea Pigs are not exceptional. All creatures on the earth will reproduce according to their habitats. When they are in captivity, you have to care for them as they could care for themselves in the wild. This is the only way to keep your pregnant pets healthy.

Sexual maturity of Guinea Pigs

The male and female Guinea pigs attain sexual maturity around 3-4 months of age. If you have male and female Guinea pigs together make sure you separate them or else they are likely to breed.

Mating in Guinea Pigs

It is better if the female guinea pig is older than the male guinea pig and weighs about 400gm. During mating, you have to keep the male and the female guinea pigs together in the same cage and it’s better to leave them alone.

The oestrus cycle in female guinea pigs lasts for 16 days and during this time the female would be interested in liaising with the male-only for the eight hours.

Why should you remove the male Guinea pig from the cage?

The female guinea pig like to stay without any disturbance. If you do not remove the male guinea pig , that could make the female pregnant again soon after the female guinea pig gives birth. This will reduce the quality of health of the female guinea pig , and may make her milk supply dry up.

How long is the gestation period?

The gestation period lasts for 9 – 10 weeks and the female may produce 1 – 6 babies at a time.

How to find whether the female is ready to give birth?

It is quite difficult to tell this as female guinea pigs don’t do any activities like burrowing or build a nest when they are about to give birth. But you can identify by observing their pelvis. Her pelvis widens about 2.5 cms or even more when they are about to give birth but this is a slow process and doesn’t happen in a day.

Diet for Pregnant Guinea Pigs

During the pregnancy period replace the Timothy Hay with Alfalfa as it provides more calcium and protein content required for the pregnant mom.

Usually, it is important to give your Guinea pigs vitamin C enriched foods because they won’t be able to synthesize vitamin C on their own. During pregnancy, female guinea pigs need thrice the amount of vitamin C that they need on normal days.

You can either add the 200mg vitamin C in the water/liter or give vitamin enrich foods like,

Dandelion greensCauliflower
KaleStrawberries
Brussel sproutsBroccoli florets
ParsleyOranges
Broccoli leavesCabbage

Pregnant guinea pigs drink more water than they normally drink so always make sure they never run out of water. Since they eat and drink more, female guinea pigs gradually increase in weight, and no need to worry about it.

During birth

Complications in giving birth are quite common in Guinea pigs and may even lead to the death of the mother. So it is highly advised to seek a vet few weeks before the birth.

Sometimes the mother doesn’t require any assistance while giving birth but sometimes caesarean section would be required. So while giving birth request your vet to be at your place to tackle any complications if required.

After that the mom will eat the after birth which is quite normal and the female will clean her babies by doing this.
