Offspring and rearing

In general, the onset of sexual maturity in guinea pigs can vary greatly. Thus, precocious females sometimes become sexually mature at the age of three to four weeks, others only a few weeks later. Males become sexually mature at four to eight weeks, some much earlier. Guinea pigs – both female and male – should only be used for breeding from the age of six months.

After successful mating, the female is pregnant for an average of 68 days and gives birth to one to seven young. The birth usually takes place in the early morning hours or at night and lasts about 30 to 60 minutes. As precocial, guinea pigs are born completely hairy and with permanent teeth.

The guinea pig babies can already see and hear and weigh around 60 to 80 grams. In addition to their mother’s milk, the animals eat solid food such as hay and dry food after just a few hours or days. The rodents learn healthy social behavior from their mother and other group members. It is also possible to keep several mothers with young animals of the same age together. The females get along well and even raise their litters together. The young should stay with the mother for at least three to four weeks (as long as possible).

Keeping smooth-haired guinea pigs

Due to its short, dense coat, the smooth-haired guinea pig is relatively easy to care for and is therefore also well suited for guinea pig beginners.

Smooth-haired guinea pigs can be kept indoors or in the garden all year round. Since guinea pigs are very social and sociable animals, they should never be kept alone. You need at least one conspecific. A rabbit cannot replace this conspecific! The enclosure for two to four animals should have a floor area of at least 2m², for each additional animal it must be enlarged by at least 0.5m².

The enclosure consists of a feeding and drinking bowl and at least one sleeping hut, which should be large enough for several guinea pigs to lie in it at the same time.

In addition to a large and varied enclosure, healthy nutrition is one of the most important aspects of keeping guinea pigs. The main feed should consist of high-quality hay (freely available), fresh feed (grasses, herbs, vegetables, and fruit), and, if necessary, small amounts of dry feed. Pellets rich in crude fiber (pressed feed made from hay, grass, and herbs) that contain neither grain, sugar nor molasses are suitable as dry feed. Fresh drinking water must always be available to the animals.

In addition, it is important that you regularly check your guinea pig for diseases and carry out a daily health check.
