Causes and Prevention of Infertility in Rabbits

Male rabbit infertility can result from a variety of factors, not limited to abnormalities in the reproductive organs. Endocrine imbalances, nutritional deficiencies or excesses, infectious diseases, exposure to high ambient temperatures, excessive light exposure, and prolonged lighting periods can all contribute to male infertility. These environmental and physiological conditions can negatively impact sperm production, motility, and overall reproductive health. Similarly, female rabbits may also experience infertility due to congenital issues such as genital malformations, which can hinder the fertilization process by preventing proper interaction between sperm and egg. Nutritional imbalances—whether due to insufficient or excessive nutrients—can lead to obesity or extreme thinness, both of which disrupt normal reproductive function. Additionally, diseases affecting the reproductive system, such as endometritis, salpingitis, vaginitis, and uterine tumors, can significantly impair fertility. To prevent these issues, it is crucial to separate male and female rabbits in different housing environments with controlled lighting conditions. The feed provided should be nutritionally tailored to meet the specific needs of each sex. In practice, infertility caused by obesity, vitamin A or E deficiency, drug toxicity, or heat stress is quite common and should be addressed proactively. For infertile rabbits, adjusting the diet to ensure balanced nutrient intake and providing adequate sunlight exposure can be beneficial. Medical interventions such as intramuscular injections of follicle-stimulating hormone (0.6 grams twice daily) or subcutaneous injections of pregnant mare's serum (70 international units) may be used under veterinary guidance. However, precise dosing is essential, as improper administration can worsen the condition rather than improve it. By addressing both environmental and health-related factors, rabbit breeders can significantly improve reproductive success and maintain healthy breeding populations. Regular monitoring, proper nutrition, and timely medical intervention are key to managing and preventing infertility in rabbits.
