Causes and Prevention of Infertility in Adult Rabbits

Reasons for Infertility in Rabbits

Infertility in rabbits can stem from various factors, each requiring careful consideration and appropriate management.

Functional Infertility

1. Agerelated infertility: Rabbits older than 2.5 years often lose their reproductive capabilities. It is advisable for breeders to select breeding rabbits between the ages of 0.5 to 2.5 years.

2. Longterm nonparticipation in breeding can lead to ovarian atrophy in female rabbits, resulting in temporary reproductive dysfunction. To address this, breeders can feed the rabbits with malt or administer fertility stimulants to boost ovarian activity. Once the female rabbit is in heat, introducing a male rabbit with strong libido can stimulate her to mate. After several mating sessions, the female rabbit typically regains her reproductive capacity.

3. Reproductive organ diseases: Conditions such as ovarian cysts, vaginitis, or underdeveloped reproductive organs can cause infertility in rabbits. Even after treatment, rabbits with such diseases are not suitable for breeding purposes.

Nutritional Infertility

Nutritional infertility in rabbits is primarily due to improper feeding management, such as a monotonous diet and a lack of essential nutrients like proteins and vitamins. Overweight or underweight rabbits can also contribute to infertility. Therefore, it is crucial for breeders to maintain a diverse diet for rabbits, ensuring they receive adequate minerals and trace elements. Opt for complete feed formulations when possible. If not, consider supplementing the diet with cooked soybeans and bran a month before breeding. Address issues of obesity and emaciation promptly to prevent these conditions from affecting reproductive success.

Other Types of Infertility

1. Incorrect breeding methods: The correct way to breed rabbits is to place the female in the male's cage, allowing the male to mount and mate with the female. Implement a remating strategy by having the same male rabbit mate with the female again 6 to 8 hours after the first attempt.

2. Lack of artificial assistance: In the case of longhaired rabbits, their extensive fur can interfere with mating. It is recommended to trim the fur around the reproductive area a month before breeding. During mating, the breeder should assist the rabbit to ensure successful breeding. For instance, tie a thin rope around the rabbit's tail to prevent it from affecting the mating process. After mating, the male rabbit may make a honking sound and lie on its side. At this point, gently lift the rabbit's hindquarters and tap its rump to prevent semen from escaping. If semen leaks out, it can lead to mating without conception.
