1.选择种兔。要求种兔生殖器官发育匀称正常、性欲旺盛,毛色纯正平整,体质强壮,眼睛有神,母兔母性强,乳头4对以上。
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.预备期的饲养。种兔配种前供给蛋白质和维生素丰富的饲料,多样搭配,适口易消化。
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.科学配种受胎。小型品种兔的初配年龄为4—5月龄,中型品种5—6月龄,大型品种7—8月龄,可实行双重配种,即与一只公兔配种后10—20分钟再与另一只公兔交配,后代适于商品兔用;也可实行重复配种,初次配种后6—8小时再用同一只公兔重配,后代可选留种用。
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。可用促卵泡生长素、三合激素按每次0.5—1毫升肌注,4—6时后配种,也可用性诱催情、气味催情等,促进发情及时配种。
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.及时查胎防空怀。①复配法:母兔配种后5—6天再放到公兔笼内,拒配则已孕。②摸胎法:母兔配种后8—10天,用手呈八字型从腹部由前向后摸到花生米大小的肉球滑去则已孕。发现母兔未孕应及时催情配种。
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.加强分娩护理。母兔妊娠期平均为30—31天,产前7—8小时拉毛衔草做窝。母兔产仔多在凌晨时分,应做好接产准备。
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.怀胎期和哺乳期的饲养。孕兔前期营养水平稍高于空怀期,后期增补豆类、骨粉、鱼粉等饲料。哺乳期前15天应补鱼粉等饲料。母兔缺奶则喂豆浆和红糖水等。保持兔舍安静。
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.精心饲养育壮兔。分娩仔兔及时吃上初乳,15日龄开食补饲,及时滴服0.5%的甘草水(每100毫升含红糖10克、葡萄糖0.05克、敌菌净0.05克)。35—42日龄仔兔可断奶。
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.优化兔群结构。种兔利用年限2—3年,凡体弱有病、性欲降低、年龄偏大的种兔均应淘汰。及时补进青年兔,确保种兔年龄结构的合理。
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.
