Introduction: The Puzzling Case of Stillborn Guinea Pigs

Guinea pigs are popular pets around the world. They are affectionate and social, making them great companions for both children and adults. However, guinea pigs are prone to stillbirth, which is a devastating experience for pet owners and breeders alike.

Stillbirth is a term used to describe the death of a fetus during pregnancy or birth. In guinea pigs, stillbirth occurs more frequently than in other rodent species, and it is a complex phenomenon that involves several genetic and environmental factors. In this article, we will explore the reasons why guinea pigs are stillborn, how to diagnose and manage stillbirth in guinea pig pregnancies, and the best practices for preventing stillbirth in guinea pig breeding.

Understanding the Anatomy and Reproduction of Guinea Pigs

Guinea pigs are small rodents that belong to the family Caviidae. They have a unique reproductive system that involves two uteri and two cervices. This means that guinea pigs can become pregnant in both uteri simultaneously, leading to the birth of up to four offspring per litter. However, this also means that guinea pigs are more prone to complications during pregnancy, such as dystocia (difficulty giving birth) and stillbirth.

During pregnancy, guinea pigs undergo several hormonal changes that prepare their bodies for childbirth. The gestation period for guinea pigs is around 63 days, and the mother guinea pig (also known as a sow) can give birth to between one and four pups per litter. Guinea pigs are born fully furred and with their eyes open, and they are immediately able to move around and feed from their mother. However, stillbirth can occur at any stage of pregnancy or during birth, leading to the death of the fetus and potential complications for the mother.
