Adding vitamin E and carotene can significantly improve the reproductive performance of female rabbits. Practical experience has shown that providing a specific amount of carotene and vitamin E to does can enhance their ability to breed multiple times. The recommended method is: starting from the third day after weaning, each female rabbit should be given 40 mg of vitamin E and 80 mg of carotene per kilogram of body weight daily. When the female rabbit is in estrus, reduce the dosage by half and continue feeding for 20 days. This approach helps support fertility and increase litter size.
The tapping technique is another effective method to boost litter size. After mating, gently tapping the female rabbit's hindquarters can help stimulate her reproductive system. This action causes the muscles around the vulva to contract, which helps the semen move deeper into the vagina, reducing its loss and increasing the chances of successful fertilization.
The double mating method is also widely used to improve breeding success. After the first mating, if the same male rabbit is used again within 5 to 6 hours, it can greatly increase the chances of pregnancy. This method ensures that more sperm are available to meet the eggs, thereby improving fertility rates and leading to larger litters.
In addition to these methods, maintaining good nutrition, proper housing, and regular health checks are essential for maximizing the reproductive potential of your rabbits. A well-balanced diet rich in essential vitamins and minerals will not only support fertility but also ensure the health of both the mother and her offspring. Consistent monitoring and care will lead to better breeding outcomes and a more productive rabbitry.
