Methods to Increase the Conception Rate in Meat Rabbit Breeding
The autumn climate is suitable, meat rabbits have a strong appetite, their reproductive function is active, and the conception rate is high.
Generally speaking, when a doe is in estrus, the conception rate from mating is high, so the rabbit herd should be checked frequently for estrus, so that estrus is detected promptly and mating is carried out promptly. When mating, care should be taken to place the doe into the buck's cage for copulation, and after copulation promptly lift the doe's hindquarters and pat them twice with the hand to promote contraction of the vagina and uterus and prevent semen from flowing out. For mating, natural mating methods such as double mating, repeat mating and blood mating may be used, and where conditions permit, artificial insemination technology may also be used. For individuals that have long been without estrus, in addition to strengthening feeding and management, physical or chemical methods should also be used to induce estrus.
According to observations, within a single day, the conception rate from mating at 12 noon is the lowest, only 50%; it is next lowest in the evening; and the conception rate from mating at 24 midnight is the highest, reaching 84%. In production, mating at 21-22 in the evening should be advocated. In addition, Chinese herbal medicines can also help with conception.
