In rabbit farming, it's common to encounter female rabbits that fail to show estrus or become pregnant. This issue can lead to significant economic losses for breeders. By identifying and addressing reproductive problems in females, their lifespan can be extended, and the profitability of raising rabbits can be significantly improved.
Beyond eliminating congenital genital abnormalities, if a female rabbit still does not go into heat or conceive despite receiving adequate energy, protein, vitamins, and minerals, the following strategies may help stimulate estrus and improve fertility:
1. **Change in Housing Environment**: Move non-estrus females into a larger cage or a more stimulating living space. A change in surroundings can often encourage estrus by reducing stress and increasing activity levels.
2. **Increase Physical Activity**: Allow non-estrus females to spend 2 hours each morning and evening outdoors for 5–7 consecutive days. This increased movement can enhance their overall health and stimulate reproductive function, especially in those who are otherwise healthy but not showing signs of estrus.
3. **Male Rabbit Stimulation**: Introduce male rabbits daily to stimulate the females. The presence and scent of males can trigger hormonal responses in the female’s pituitary gland, promoting ovulation and estrus.
4. **Drug Injection**: Administer 1–2 ml of ethinyl estradiol intramuscularly. After 2–3 days, the female may enter estrus, though she may not ovulate immediately. It is recommended to wait for natural estrus in the following week before breeding. Alternatively, a triple hormone injection (1–2 ml) can also be used to induce estrus and ovulation effectively.
5. **Traditional Herbal Remedy**: Prepare a herbal decoction using 10 grams each of Rehmannia, Angelica sinensis, and Epimedium, 6 grams each of licorice root, Poria, and Glycyrrhiza, and 2 grams of Cinnamon twig. Boil these ingredients together, add sugar and a small amount of rice wine, and feed 10 ml three times daily. After three days of continuous use, this remedy has shown effectiveness in helping long-term non-estrus females to ovulate and conceive.
By implementing these methods, farmers can improve reproductive success and reduce losses associated with infertile or non-estrus females. Regular monitoring and a combination of environmental, behavioral, and medical approaches often yield the best results.
