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。

　　There is a significant difference in the fecundity between different kinds of rabbits, such as meat and rabbits, and their reproductive power is generally higher than that of skin and hairy rabbits. When breeding varieties are chosen at the beginning of construction stage, reproductive performance should be considered as an important content while laying stress on production performance (growth speed, wool yield and so on).

　　同一品种个体间繁殖力有差异，因此通过严格选种，可以使兔群繁殖力得以提高。选留种兔时，要求健康、体质健壮、性欲旺盛，同时要根据系谱、繁殖记录、生产性能等进行选留。个体一般从窝产仔数高的母兔后代中选取。母兔要求母性好、乳头在4对以上、外阴端正。公兔要求睾丸大而对称。隐睾或单睾公兔不能留作种用。

　　The fecundity of the same species is different. Therefore, by strictly selecting seeds, the fecundity of rabbits can be improved. When selecting and keeping rabbits, they should be healthy, physically strong and have strong desire. Meanwhile, they should be selected according to pedigree, reproductive records and production performance. Individuals are usually selected from the offspring of female rabbits with high litter size. The female rabbit requires good maternal performance, 4 nipples in the nipple and right vulva. The male rabbits require large and symmetrical testicles. The cryptorchidism or the single testosterone male rabbit can not be used as seed.

　　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。

　　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.
