Appropriate Age Of Breeding Guinea Pigs

Surprisingly, female guinea pigs attain sexual maturity at a very young age.

A female guinea pig getting pregnant at six weeks is not something peculiar among their species. Guinea pigs usually reproduce from 4 to 8 weeks old. 

With that being said, you should separate younger guinea pigs so that you can prevent unwanted pregnancies.

Besides that, it is also vital that you select a female guinea pig of a certain age whenever you decide to breed them.

Appropriate Age Of Breeding Guinea Pigs

You should choose a female guinea pig that is not too young and not too old at the same time. A minimum of three months old is what the authorities generally recommend. 

There’s this strange quirk between guinea pigs’ biology that their ligaments that are joining the pelvic bones together can harden as they age. This is said to make birthing difficult for them. 

So in older guinea pigs, a Caesarean might be needed. But this has a considerable amount of risks. The only good in this is that mother and its young ones are unlikely to die due to this process.

It is also ideal that female guinea pigs used as a sire were bred before she turns six months old. Doing so can help in setting her hips as well as make future pregnancy less fraught. 

Male guinea pigs, on the other hand, can be bred at almost any age. Ginger started mating when he was two months old.

However, older males are said to tend to lose their vigor.

How To Introduce The Pair?

Guinea pigs are generally friendly and docile creatures.

Only the adult males or the boars will most likely engage in fights. Female ones don’t, or if they do, just very rarely.

The best way of introducing the pair is to put the male into the cage of female guinea pigs. You can learn more about how to introduce guinea pigs in this article. 

Doing so will reduce the stress on the part of the female. It is also ideal that you keep an eye on them in order to make sure that they are really getting together.

You will know if the male is interested in the sow as he will usually make an exciting sound.

Sometimes, he would also walk around the female guinea pig funnily. You can leave them together if you are already confident that the female is pregnant.

You should take away the boar after 48 days.

Despite the fact that the majority of boars do not hurt their babies, if you let them stay, he will probably want to mate with the mother again right after she gives birth.

This is absolutely true as I have seen this myself; Ginger dared to mate with the mother moments after she gave birth.

So from then on, I always separate him from the sire.

How Do I Identify Whether My Guinea Pig Is Pregnant Or Not?

If you notice that your guinea pig’s food intake increases dramatically, then it could be an obvious sign that she is pregnant.

Later on, you will see that she puts on weight. You can also try to feel the babies in her tummy. But make sure to handle her very gently.

Gestation In Guinea Pigs

The gestation periods among guinea pigs dramatically vary. On average, the gestation period takes up to 60 to 70 days.

Take note that:

The longer the gestation period, the higher the chance of a miscarriage.

In this case, the mother requires additional care.

In as much as possible, you should avoid handling your guinea pig. That is because frequent handling can cause stress to her.

But other than that, it can also cause accidental injuries to the baby.

Furthermore, you should serve plenty of water and food to the mother while emphasizing foods rich in calcium, such as watercress, spinach, kale, okra, collard greens, and more.

Giving Birth 

The litter of guinea pigs is small. Thus, on average, they can only carry between 1 and 4 piglets.

However, some experienced sire has larger litters and carries several piglets that are more than the average.

At birth, the young ones are astonishingly developed. They might be seen trying out adult foods just within days.

Typically, baby guinea pigs are totally weaned within 14 up to 28 days.

At this time, you should separate both sexes from one another in order to avoid unwanted pregnancy.


How to breed guinea pigs? Before asking this question, you should first know whether you are ready to take care of more guinea pigs.

Deciding to breed your guinea pigs comes with responsibility. Baby guinea pigs are not just cute little creatures that can give you pleasure when they are born. But, they have life and they come with a  lot of responsibilities for you.

You need to sustain the baby guinea pigs until they grow up. That is also why it is important to avoid unwanted pregnancies since it will also prevent putting you in a situation where you cannot take care of the young ones.
