Enhancing Breeding Success: Tips for Increasing Rabbit
Strategies to Enhance the Fertility Rate in Rabbit Breeding
1. The foundation of improving the fertility rate in rabbit breeding lies in restoring the sexual function of the male rabbits and enhancing the quality of their semen. It is widely recognized that the fertility of female rabbits largely depends on the quantity and vitality of the sperm. Here are some methods to stimulate the recovery of the male rabbits' sexual function:
① Inducing Estrus: During the estrus period, placing the male and female rabbits together can promote the recovery of the male rabbits' testicular function.
② Testicular Massage: Massaging the male rabbits' testicles can improve blood circulation and stimulate tissue growth. It is recommended to massage the rabbits twice a day for 3 to 5 minutes, ensuring proper pressure control.
③ Hormonal Stimulation: Administering 0.5 micrograms of PMSG (Pregnant Mare Serum Gonadotropin) intramuscularly to the male rabbits once a day. After five injections, the semen quality of the male rabbits generally improves. Alternatively, inject 0.5 micrograms of "3号3" hormone into the male rabbits every other day for five consecutive days.
It is important to note that the recovery of the male rabbits' sexual function requires a certain amount of time. Once the sperm is killed, it takes approximately 50 to 60 days for new sperm to regenerate. Patience is key, as the process cannot be rushed.
2. Breeding female rabbits during the peak of their estrus can increase the fertility rate by 20% to 30%. For female rabbits that have difficulty in estrus, induced estrus can be achieved, or hormones such as chorionic gonadotropin, luteinizing hormone, triple hormone, and PMSG can be administered to stimulate estrus. Additionally, the following methods can be highly beneficial in promoting estrus:
• Add 10% of Epimedium or half a coin of韭菜籽 to the rabbit's feed, and mix it for 10 consecutive days.
• Add an appropriate amount of betacarotene to the rabbit's feed, with 40mg per kilogram of feed.
• Trim the hair around the female rabbit's vulva before breeding.
In summary, there are numerous methods to stimulate estrus in female rabbits. The keeper should choose the most appropriate method based on the specific conditions of the rabbits.
3. Additional Measures to Improve the Fertility Rate in Rabbit Breeding:
① Based on the rabbit's ovulation characteristics, implement repeated mating or double mating methods to increase the chances of conception.
② Regularly check the female rabbits. After 8 days of mating, perform a pregnancy check. If the rabbit is not pregnant, remate to shorten the barren period. If the rabbit has reproductive system diseases, treatment or culling should be carried out promptly.
③ For healthy male and female rabbits, under the premise of strengthening the nutritional content of the rabbit feed, adopt frequent or semifrequent mating methods to improve fertility and breeding speed.
In conclusion, these are the methods summarized by Oxygen Pet Doctor to enhance the fertility rate in rabbit breeding. We hope these strategies will be helpful to rabbit farmers, effectively improving the fertility rate of rabbit breeding.
