家兔不能在发情期内同时自然排卵，排卵要靠交配的刺激来诱发。若无交配的刺激，成熟的卵子就会在卵巢中退化萎缩。适龄的母兔如长期不适时配种，退化萎缩的卵子便蓄积在卵巢内，造成卵巢机能早期退化。晚配种或两次配种间隔时间太长，也会导致同样的恶果。
The rabbit can not be natural ovulation during the estrus, ovulation stimulation depends on mating induced. If there is no mating stimulation, mature eggs will atrophy and atrophy in the ovary. If the age of the mother rabbit, such as a long period of time is not timely breeding, atrophy and atrophy of the eggs will accumulate in the ovary, resulting in premature degradation of ovarian function. Late breeding or two mating interval is too long, it will lead to the same consequences.
因兔的繁殖期没有季节性。母兔一般在分娩后第二天又开始发情。没有怀孕的母兔，每隔8~10天即发情1次，每次持续3-5天。在发情期应进行交配。交配后，精子可在母兔生殖道中生活一昼夜。母兔在交配后约经10-12小时开始排卵，如果此时精子和卵子相遇，就会受精。家兔是多胎动物，有把泌乳期和怀孕期完全结合的能力，但考虑到母兔的健康、仔兔的强壮，在繁殖适龄期（出生后7-8个月）的家兔，每年配种产仔以5胎为宜。
Because the rabbit breeding season is not seasonal. The female rabbits usually begin to estrus after second days. There is no pregnant mother rabbit, every 1 days, namely, estrus 8~10, each lasting 3-5 days. Mating should be carried out during estrus. After mating, the sperm can live a day and night in the female reproductive tract. The female rabbit begins to ovulate about 10-12 hours after mating, and if the sperm and egg meet at this time, they will fertilize. The rabbit is a prolific animal, has the ability of lactation and pregnancy fully integrated, but considering the female rabbit pups healthy, strong in the reproductive age (7-8 months after birth) in rabbits, the annual breeding litter by 5 fetal.
根据实践证明，用来繁殖的公、母兔，它们的品种、年龄和饲养条件之间的差异越大，母兔的受胎率越高，仔兔也越强壮。品种间的杂交后代，具有生命力强、体型大、生长发育快的特点，而且对饲料的利用率高，抗病力强。因此，在繁殖家兔时，应选择品种、年龄不同的、血缘较远的，而且在不同的兔场培育出来的公、母兔来进行配种。
According to the practice, for the reproduction of male and female rabbit, there are differences between the species, age and rearing conditions more, female rabbit pregnancy rate is high, the more strong young rabbit. The hybrid offspring of the varieties have the characteristics of strong vitality, large size, rapid growth and development, high utilization ratio of feed and strong disease resistance. Therefore, in breeding rabbits, should choose different varieties, age, blood is far, and cultivated in different male and female rabbit to rabbit breeding.
每头公兔一天可配种3-4次，但要适当增加营养。配种时间，夏天宜在清早或傍晚，冬季宜在中午进行。交配时间最好在母兔发情中期。母兔发情时有如下表现：精神不安，食欲减退甚至废食，频频向四处抓扒，有时口衔笼中草料，不时发出叫声。检查外阴时，初期呈淡红色，中期红肿湿润，后期变为紫色。当母兔进入发情中期阶段，可把母兔抓到公兔笼去配种。公兔若抓去配种，要很长时间才能适应新的环境，所以不要把公兔抓到母兔笼去配种。
Each male rabbit can breed 3-4 times a day, but should be appropriately increased nutrition. Breeding time, Xia Tianyi in the early morning or evening, winter should be at noon. The mating time was best in the middle stage of female rabbits. When the mother of the rabbit has the following performance: mental anxiety, loss of appetite and even waste food, frequently to grab around the mouth, sometimes the mouth of the cage in the grass, from time to time issued a call. Examination of the vulva, the initial pale red, red and humid in the middle, late into purple. When the mother rabbit entered the middle stage of estrus, the female rabbit hutch to catch male mating. If the male rabbit caught breeding, take a long time to adapt to the new environment, so don't get to parent breeding male rabbit hutch.
