Adding vitamin E and carotene can significantly improve the reproductive performance of female rabbits. Practical experience has shown that supplementing a certain amount of carotene and vitamin E to the diet of female rabbits at the right time can enhance their fertility and increase litter size. The recommended method is to start from the third day after weaning the kits, and provide each kilogram of body weight with 40 mg of vitamin E and 80 mg of carotene daily. When the female rabbit is in estrus, reduce the dosage by half and continue feeding for about 20 days. This practice helps maintain hormonal balance and supports healthy ovulation.
The tapping technique is another effective method to boost litter size. After mating, gently tapping the female rabbit’s hindquarters can stimulate uterine contractions. This action helps the semen move deeper into the reproductive tract, reducing the chances of it being expelled and increasing the likelihood of successful fertilization. Many breeders have reported better results when this simple technique is used in conjunction with proper nutrition and breeding management.
The double mating method is also widely used to improve fertility rates. After the first mating, the same male rabbit is introduced again after 5 to 6 hours. This second mating increases the chances of successful fertilization by ensuring a higher concentration of sperm in the reproductive tract. It is especially useful in cases where the first mating may not have been fully effective. This method has proven to be a reliable way to increase both the number of offspring and the overall productivity of the breeding program.
Combining these techniques—nutritional supplementation, physical stimulation, and strategic mating—can greatly enhance the reproductive success of your rabbit herd. By paying attention to these small but important details, you can achieve better breeding outcomes and improve the health and vitality of your rabbits over time.
