There are many factors that affect the embryo utilization rate of female rabbits, which are closely related to variety, growth and development, nutritional status, mating age, mating time, season, mating mode, etc. The common methods to improve the pregnancy rate were introduced

　　1)选好雄、雌兔:根据雄、雌兔的选择要求，选择繁殖性能好的品种，选优。

　　1) Select the male and female rabbits: according to the selection requirements of male and female rabbits, select the breed with good reproductive performance and select the best one.

　　2)适时交配:即适时的初次交配和更佳发情期的交配。

　　2） Mating at the right time: the first mating at the right time and the mating at the best estrus.

　　3)多育种商品兔的生产:即同一品种或不同品种的两只公兔先后与同一母兔交配。一次交配后，第二次交配将在5-10分钟后进行。这样可以提高受孕率，并对育种兔适应性强，成活率高，生长快。

　　3) Production of multi breeding commercial rabbit: that is, two male rabbits of the same variety or different varieties mate with the same female rabbit successively. After the first mating, the second will take place in 5-10 minutes. In this way, the conception rate can be improved, and the adaptability to breeding rabbits is strong, the survival rate is high, and the growth rate is fast.

　　4)纯育种重复交配:一次交配后，每隔5-8分钟与同一雄兔进行另一次交配。这样使母兔的输卵管内有较长时间内具有较强活力的精子，使卵巢教育增加的卵子成为受孕器即可。

　　4) Pure breeding repeated mating: after the first mating, another mating with the same male rabbit every 5-8 minutes. In this way, the female rabbit's oviduct has strong motile sperm for a long time, and the egg with increased ovarian education can become a conception device.

　　5)交配后，肌肉注射50单位绒毛膜促性腺激素(HCG)或静脉注射25单位绒毛膜促性腺激素可促进排卵和多胎妊娠。保证母兔受孕和提高受孕率的关键是保证公兔和母兔的正常营养水平，保证高质量、有活力的精液的存在，正确掌握发情交媾期。养兔场不提倡重复育种和亲本育种，其原因是不利于雄兔的饲养。太多的婴儿，对母亲的伤害，没有足够的牛奶吃，也会造成高死亡率。

　　5) After mating, intramuscular injection of 50 units of hCG or intravenous injection of 25 units of hCG can promote ovulation and multiple pregnancy. The key to ensure the conception of female rabbits and improve the conception rate is to ensure the normal nutrition level of male and female rabbits, to ensure the existence of high quality and active semen, and to correctly master the oestrus and copulation period. Repeated breeding and parent breeding are not advocated in the rabbit farm because it is not conducive to the breeding of male rabbits. Too many babies, harm to the mother, not enough milk to eat, can also cause high mortality.
