Adding vitamin E and carotenoids has been shown to significantly enhance the reproductive performance of female rabbits. When provided with an appropriate amount of carotene and vitamin E at the right time, it can promote multiple breeding cycles. The recommended method is to start on the third day after weaning: administer 40 mg of vitamin E and 80 mg of carotenoids per kilogram of body weight daily. Once the female rabbit shows signs of estrus, reduce the dosage by half and continue feeding for 20 days. This approach helps improve fertility and supports better litter outcomes.
Another effective technique involves gently slapping the hindquarters of the female rabbit after mating. This action causes the muscles in the genital area to contract, which helps the semen travel deeper into the vagina and reduces the chances of it being expelled. As a result, the sperm has a better opportunity to meet the egg, increasing the likelihood of successful fertilization.
After the first mating, it's advisable to repeat the process every 5 to 6 hours using the same male rabbit. This repeated mating strategy enhances the overall fertility rate and increases the number of litters a female rabbit can produce within a given period. These methods, when applied consistently, can greatly improve breeding efficiency and productivity in rabbit farming.
