I. Functional Infertility
-
Rabbits that are too old may lose the ability to reproduce. It is recommended that owners choose breeding rabbits aged 0.5-2.5 years.
-
If female rabbits do not participate in breeding for an extended period, it can lead to ovarian atrophy, resulting in temporary loss of reproductive function and infertility. In such cases, owners can use malt or inject aphrodisiacs into the female rabbit to stimulate ovarian activity. When the female rabbit is in heat, mate it with a male rabbit with a strong sex drive. Reproductive capacity can usually be regained after a few mating stimulations.
-
Infertility caused by diseases of reproductive organs, such as ovarian cysts, vaginitis, and genital hypoplasia, may occur. If a female rabbit suffers from such reproductive organ diseases, even if cured, it is not suitable for use as a seed reserve.
II. Nutritional Infertility
Rabbit nutritional infertility is mainly due to unscientific feeding and management, including feeding a single type of feed, essential nutrient deficiencies (e.g., protein, vitamins), and improper body weight in female rabbits (too fat or too thin). Owners must diversify rabbit feed and timely supply minerals and trace elements. Ideally, use full-price compound feed for rabbits. If challenging, add concentrated feeds like cooked soybeans and bean dregs for nutritional supplements in the first half of the month of breeding. Additionally, respond promptly to overweight or underweight rabbits to prevent these issues from affecting breeding.
III. Other Types of Infertility
-
Inappropriate breeding methods may lead to infertility. The correct method involves placing the female rabbit in heat into the male rabbit’s cage and letting the male rabbit crawl across the female rabbit to mate. Implement a compound method by allowing the same male rabbit to mate 6 to 8 hours after the first mating.
-
No measures were taken to assist the mating of rabbits artificially. Long-haired rabbits may face difficulties in mating due to their hair length. Owners should shear them half a month before breeding. When breeding long-haired rabbits, tie the tail of the female rabbit with a string to prevent it from affecting mating. After mating, raise the rear drive of the female rabbit slightly, pat the buttocks gently, preventing semen from flowing out, as it may cause the female rabbit not to get pregnant.
The above is our analysis of the causes of infertility in adult rabbits and the introduction of some related prevention measures. We hope it can help you!
