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)選好雄、雌兔:根據雄、雌兔的選擇要求，選擇繁殖性能好的品種，選優。

　　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)適時交配:即適時的初次交配和更佳發情期的交配。

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

　　3)多育種商品兔的生產:即同一品種或不同品種的兩只公兔先后與同一母兔交配。一次交配后，第二次交配將在5-10分鐘后進行。這樣可以提高受孕率，并對育種兔適應性強，成活率高，生長快。

　　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)純育種重復交配:一次交配后，每隔5-8分鐘與同一雄兔進行另一次交配。這樣使母兔的輸卵管內有較長時間內具有較強活力的精子，使卵巢教育增加的卵子成為受孕器即可。

　　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單位絨毛膜促性腺激素(HCG)或靜脈注射25單位絨毛膜促性腺激素可促進排卵和多胎妊娠。保證母兔受孕和提高受孕率的關鍵是保證公兔和母兔的正常營養水平，保證高質量、有活力的精液的存在，正確掌握發情交媾期。養兔場不提倡重復育種和親本育種，其原因是不利于雄兔的飼養。太多的嬰兒，對母親的傷害，沒有足夠的牛奶吃，也會造成高死亡率。

　　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.
