Adding vitamin E and carotenoids has been shown to enhance the reproductive performance of female rabbits. When given an appropriate amount of carotene and vitamin E at the right time, it can significantly improve their ability to breed multiple times. The recommended method is to start on the third day after weaning the young. For each kilogram of body weight, administer 40 mg of vitamin E and 80 mg of carotene daily. Once the female rabbit shows signs of estrus, reduce the dosage of both supplements by half and continue feeding them for a period of 20 days.
Another effective technique to increase the farrowing rate is to gently slap the hindquarters of the female rabbit during mating. This action causes the muscles in the area to contract, which helps the uterus to shrink slightly. As a result, the semen is pushed deeper into the vagina, reducing its loss and increasing the chances of sperm and egg meeting successfully.
After the initial mating, the same male rabbit should be used again every 5 to 6 hours. This repeated breeding method enhances the fertility rate of the female rabbit and increases the number of litters she produces over time. By following these practices, rabbit farmers can achieve better reproductive outcomes and improve overall productivity in their breeding programs.
