1、家兔不同用途的品种之间繁殖力存在明显差异，如肉用兔、皮肉兼用兔繁殖力一般高于皮用兔和毛用兔。建场初期选择饲养品种时，在注重生产性能(生长速度、产毛量等)的同时，应把繁殖性能作为重要内容加以考虑。
1. There is a significant difference in the fecundity between different kinds of rabbits. For example, the reproductive capacity of meat rabbits and meat rabbits is generally higher than that of skin rabbits and hair rabbits. When breeding varieties are chosen at the beginning of the construction stage, reproductive performance should be considered as an important content while paying attention to production performance (growth rate, wool yield, etc.).
2、供给种兔全价、平衡的营养物质，维持良好的种用体况是提高繁殖力的重要措施。目前多数养兔生产者配制饲粮中的能量，粗纤维基本可满足家兔的需要，但微量元素等或缺乏或使用不合理，造成母兔不发情、不排卵、受胎率低，即使受胎，胎儿死亡率、畸形率、流产率也高，公兔性欲降低、配种能力差。

2, supplying the full and balanced nutrients of the rabbit and maintaining good breeding conditions are important measures to improve the fecundity. At present, most of the rabbit producers make up the energy in the diet, and the crude fiber can basically meet the needs of the rabbit. However, the lack or use of trace elements is not reasonable, which causes the mother rabbit to be unoestrous, unovulation and low pregnancy rate. Even if the fetus is pregnant, the fetal mortality, deformity rate, abortion rate are also high, and the sexual desire of the male rabbit is lower and the mating ability is poor.
3、蒙阴长毛兔母兔发情时配种受胎率高，因此要经常对兔群进行发情检查，及时发现，及时配种。配种可采用双重、重复、血配等自然交配法，有条件者亦可采用人工授精技术。对长期不发情的个体，除加强饲养管理外，还要采用物理或化学方法进行催情。
3. Mengyin rabbit has high estrus rate when oestrus. Therefore, it is necessary to carry out estrus inspection for rabbits regularly and find out timely mating. The natural mating methods such as double, repeated and blood matching can be used for mating. In addition to strengthening feeding management, individuals who are not estrous for long periods should also use physical or chemical methods to induce estrus.
4、冬、春季节延长光照时间，每天补充光照至16小时，有利于母兔发情。夏季高温季节要采取多种降温措施，减轻高温对种兔的不良影响，避免和缩短夏季不孕期，可有效增加母兔的年繁殖胎数，从而提高群体繁殖力。
4, the winter and spring seasons to extend the illumination time, supplemented with light to 16 hours a day, is conducive to the estrus of the female rabbit. In summer, a variety of cooling measures should be taken to reduce the adverse effects of high temperature on rabbits and to avoid and shorten the summer infertility period, which can effectively increase the number of reproductive births of the mother rabbit and increase the colony's fecundity.
