Understanding How to Breed Gerbils

The Basics of Gerbil Biology

Before you dive headfirst into gerbil breeding, it’s essential to grasp the fundamentals of gerbil biology. Gerbils belong to the family Muridae and are small, burrowing rodents from arid regions in Africa and Asia. The Mongolian gerbil (Meriones unguiculatus) is the most popular choice among the gerbil species commonly kept as pets.

  1. Gerbil Species Commonly Kept as Pets

Gerbil breeding typically involves the Mongolian gerbil, known for its friendly disposition and adaptability to captivity. Understanding this species’ specific needs and behaviors is crucial for successful breeding.

  1. Explanation of Gerbil Reproductive Systems

Gerbils have unique reproductive systems tailored to their desert-dwelling lifestyle. Unlike some other rodents, gerbils are monogamous, forming lifelong pair bonds. Here’s an overview of their reproductive biology:

Male Gerbils:

  • Male gerbils (bucks) have a pair of testes and a penis.
  • They do not possess a scrotum, so the testes are located internally.
  • Bucks have a tiny gland called the preputial gland located near the penis, which plays a role in scent marking and territory establishment.

Female Gerbils:

  • Female gerbils (does) have a pair of ovaries, a uterus, and a vagina.
  • They have a unique feature called a vaginal plug, which can form after mating and prevents other males from mating with the female during her fertile period.

Understanding these anatomical differences between male and female gerbils is essential when identifying breeding candidates and recognizing signs of pregnancy.


The Breeding Lifecycle of Gerbils

Gerbils have a fascinating and well-defined breeding lifecycle. To embark on your gerbil breeding journey, it’s essential to understand the various stages of this lifecycle.

  1. Estrus Cycle and Mating Behavior

The estrus, or reproductive or heat cycle, is pivotal in gerbil breeding. During the estrus cycle, female gerbils become sexually receptive and display behaviors that signal their readiness to mate. Key points include:

Estrus Cycle Phases:

  • The estrus cycle typically lasts 4 to 6 days, with variations among individual gerbils.
  • The estrus cycle begins with proestrus, where the female exhibits subtle behavioral changes.
  • Estrus is the most fertile phase when the female is receptive to mating.
  • Diestrus follows estrus, and the female becomes less receptive.

How to Breed Gerbils

Mating Behavior:

  • Male gerbils may become more vocal and exhibit courtship behaviors, such as grooming females.
  • A female open to mating during estrus will permit the male to mount her.
  1. Gestation Period and Pregnancy Care

After a successful mating, it’s essential to provide proper care for the pregnant gerbil, a doe. Here are key points about the gestation period and pregnancy care:

Gestation Period:

  • The gestation period for gerbils typically lasts around 24 to 26 days.
  • A pregnant doe may exhibit behavior and body weight changes as pregnancy progresses.
