    母兔高產有以下幾種方法?

    發布日期:2021-04-08 來源:http://www.whxfy.cn 發布人:admin

    1.選擇種兔。要求種兔生殖器官發育勻稱正常、性欲旺盛,毛色純正平整,體質強壯,眼睛有神,母兔母性強,乳頭4對以上。
    1. Select excellent breeding rabbits. It is required that the reproductive organs of breeding rabbits should be well developed and normal, the sexual desire should be strong, the hair color should be pure and flat, the constitution should be strong, the eyes should be bright, the mother rabbit should have strong maternal nature, and the nipples should be more than 4 pairs.
    2.預備期的飼養。種兔配種前供給蛋白質和維生素豐富的飼料,多樣搭配,適口易消化。
    2. Feeding in preparation period. Before breeding, the breeding rabbits are provided with protein and vitamin rich feed, which is suitable for eating and easy to digest.
    3.科學配種受胎。小型品種兔的初配年齡為4—5月齡,中型品種5—6月齡,大型品種7—8月齡,可實行雙重配種,即與一只公兔配種后10—20分鐘再與另一只公兔交配,后代適于商品兔用;也可實行重復配種,初次配種后6—8小時再用同一只公兔重配,后代可選留種用。
    3. Scientific breeding and conception. The first mating age of small breed rabbits is 4-5 months, that of medium breed rabbits is 5-6 months, and that of large breed rabbits is 7-8 months. Double mating can be carried out, i.e. mating with one male rabbit 10-20 minutes after mating with another male rabbit, and the offspring are suitable for commercial rabbits; repeated mating can also be carried out, and the same male rabbit can be used for re mating 6-8 hours after the first mating, and the offspring can be reserved for breeding.
    4.人工催情排卵。可用促卵泡生長素、三合激素按每次0.5—1毫升肌注,4—6時后配種,也可用性誘催情、氣味催情等,促進發情及時配種。
    4. Artificial ovulation. Follicle stimulating hormone (FSH) and triad hormone (TRH) can be injected intramuscularly at a rate of 0.5-1 ml each time. They can be used to breed after 4-6 o'clock. They can also be used to induce estrus and smell estrus, so as to promote estrus breeding in time.
    5.及時查胎防空懷。①復配法:母兔配種后5—6天再放到公兔籠內,拒配則已孕。②摸胎法:母兔配種后8—10天,用手呈八字型從腹部由前向后摸到花生米大小的肉球滑去則已孕。發現母兔未孕應及時催情配種。
    5. Check the fetus in time. ① Compound method: the female rabbit was put into the cage of the male rabbit 5-6 days after mating. If she refused to mate, she was pregnant. ② The method of touching fetus: 8-10 days after mating, the female rabbit is pregnant when she touches the peanut sized meat ball with her hand in a figure of eight shape from the abdomen from front to back. If it is found that the female rabbit is not pregnant, it is necessary to breed in time.

    6.加強分娩護理。母兔妊娠期平均為30—31天,產前7—8小時拉毛銜草做窩。母兔產仔多在凌晨時分,應做好接產準備。
    6. Strengthen delivery care. The average gestational period of the female rabbit is 30-31 days, and 7-8 hours before the birth, it is used for brooding. Most of the rabbits give birth in the early morning, so they should be prepared for delivery.
    7.懷胎期和哺乳期的飼養。孕兔前期營養水平稍高于空懷期,后期增補豆類、骨粉、魚粉等飼料。哺乳期前15天應補魚粉等飼料。母兔缺奶則喂豆漿和紅糖水等。保持兔舍安靜。
    7. Feeding during pregnancy and lactation. The nutrition level of pregnant rabbits in the early stage was slightly higher than that in the empty period, and they were supplemented with beans, bone meal, fish meal and other feed in the late stage. Fish meal should be supplemented 15 days before lactation. When the rabbits were short of milk, they were fed soybean milk and brown sugar water. Keep the rabbit house quiet.
    8.精心飼養育壯兔。分娩仔兔及時吃上初乳,15日齡開食補飼,及時滴服0.5%的甘草水(每100毫升含紅糖10克、葡萄糖0.05克、敵菌凈0.05克)。35—42日齡仔兔可斷奶。
    8. Raise and strengthen rabbits carefully. The newborn rabbits were fed colostrum in time, 15 days old, and 0.5% licorice water (containing 10 g brown sugar, 0.05 g glucose and 0.05 g Dijunjing per 100 ml) in time. 35-42 day old rabbits can be weaned.
    9.優化兔群結構。種兔利用年限2—3年,凡體弱有病、性欲降低、年齡偏大的種兔均應淘汰。及時補進青年兔,確保種兔年齡結構的合理。
    9. Optimize the structure of rabbits. The breeding rabbits should be used for 2-3 years, and those with weak body, low sexual desire and old age should be eliminated. Young rabbits should be fed in time to ensure the reasonable age structure of breeding rabbits.
