Guinea pig gestation period

Guinea pigs, despite their name, neither originate from Guinea nor belong to the pig family. These small mammals are rodents, sharing only their mammalian nature with pigs. A remarkable fact about guinea pigs is that their pregnancy typically spans from 59 to 72 days, with the average birth occurring around the 65th day.

Breeding guinea pigs presents considerable challenges. It’s not a straightforward process, and complications are common. Mothers often face the risk of mortality during labor. Additionally, it’s crucial to separate male offspring to prevent conflicts and the possibility of them mating with their mother, a behavior they can exhibit after just three weeks from birth. Seeking guidance from a veterinarian is essential when considering breeding for your guinea pig, ensuring the well-being of both the mother and the offspring.
