Sharing Experience on Spring Breeding of Hares, Worth a Reference for Breeders

In spring, as temperatures rise, the fertilization rate of hares is relatively high; spring is also the peak growing season for wild grasses and forage grasses. Therefore, mastering the spring breeding of hares is the key to improving the economic benefits of hare farming. The technical key points are introduced as follows.

1. Select good breeding rabbits. For male wild rabbits, choose young and vigorous breeding bucks that are robust, well developed, genetically stable and highly sexually active. For female wild rabbits, choose young and vigorous does with well-developed reproductive organs, normal estrous cycles, high litter rates and high milk production.

2. Mating. First mating can be carried out when the breeding rabbits reach more than 70% of the adult rabbit body weight. Female wild rabbits come into estrus once every 15 days, with estrus lasting 2-3 days. The timing of mating can be determined by the color of the doe's vulva, that is, "pale pink is too early, dark red is too late, bright red is exactly the right time to mate." Mating should be arranged at night, which makes it easier to attend the birth during the day. Mating methods can be either one doe mating with one buck twice (generally 4 hours apart) or one doe mating successively with 2 male wild rabbits (generally 2 hours apart). After mating, lift the doe's hindquarters and pat them lightly a few times to make the muscles tense and prevent backflow of semen, thereby improving the doe's fertilization rate. 5-7 days after mating, place the female wild rabbit in the male wild rabbit's cage. If the female wild rabbit refuses the male wild rabbit's mounting, it indicates that the doe has conceived; otherwise, re-mating is required.
