        1、檢查種公兔,創造適宜的環境。配種前要對種公兔進行檢查,凡體弱、發育較差、有病以及有血緣關系的公兔,都不能交配。有條件的地方還應對種公兔進行精液品質檢查。確定了公兔后,將公兔籠中的食具全部移出,并在籠底墊一塊大木板,以免兔爪夾入籠縫中扭傷。
        1, check the male rabbit, creating suitable environment. To check on the kind of male rabbit mating, where the frail, poor development, disease and unrelated male rabbit, are not mating. Conditional place should also kind of male rabbit semen quality inspection. To determine the male rabbit, the male rabbit hutch utensils in all removed, and in the cage bottom a large piece of wood, so as to avoid the rabbit claw sandwiched cage seam sprain.
        2、將母兔放入種公兔籠內進行配種。把發情良好、身體健康、適宜配種的母兔輕輕放入公兔籠內進行配種。不能將公兔放入母兔籠內進行配種,若將公兔放入母兔籠內,公兔因環境的改變,容易影響性欲活動,甚不爬跨母兔,導致配種失敗。

        2, the mother rabbit hutch of mating within into male. Have good health, estrus, proper mating female rabbit hutch gently into the public within the breeding. Can not be into the mother of male rabbit hutch in breeding, if the male rabbit hutch in male rabbits in the female, because of the change of the environment, easy to affect sexual activity, and even non intromission mother rabbit breeding, lead to failure.
        3、配后處理。配種結束后,立即在母兔的臀部用力拍一下,母兔后體一緊張,即可將精液深深吸入,有利于精子從陰道向子宮方向移動,并防精液逆流。爾后將母兔從公兔籠內取出,檢查外陰部有無假配,并將母兔送回原籠,及時做好配種登記工作。
        3, after the treatment with. After mating, immediately in the female rabbit buttocks force pat, mother rabbit after a tense, semen can be inhaled deeply, conducive to sperm moves from the vagina to uterus direction, and anti sperm reflux. Then the mother rabbit is removed from the male rabbit hutch, check the vulva has no false matches, and the mother rabbit back to the cage, timely registration of breeding.
        4、復配。為了確保母兔妊娠和防假孕,要進行復配。復配的方法有兩種。⑴重復配種。在第1次配種后6-8小時再用同一公兔重配一次。據試驗,重復配種的受胎率可達95-100%。⑵ 雙重配種。第1次配種后10分鐘左右再用另一公兔作第2次交配。據試驗,采取雙重配種的受胎率比單配可提高25-30%。此法只適于商品兔生產,因為作種時無法判斷父系的血緣。
        4, the compound. In order to ensure that the Mother Rabbit anti pregnancy and pseudopregnancy, must carry on the complex. There are two kinds of compound method. The remating. In the first hours after mating 6-8 use the same male rabbit with a heavy. According to the experiment, repeated mating conception rate can reach 95-100%. The double mating. 10 minutes first times after mating with another male rabbit second mating. According to the experiment, take double mating conception rate than a single distribution can be improved by 25-30%. This method is only suitable for rabbit production, because can not judge the paternal kinship as time.
