一、有慢性呼吸道疾病的如打喷嚏，鼻有浆液性或脓性分泌物等，这些慢呼疾病一般规模兔场都有，只是数量的多少和程度的轻重不同而已，要想根治它极难，各位兔友介绍的方法我基本上都用过，缓解症状可以，不能根除，为避免人力时间金钱的无谓消耗和藕断丝连的慢性传染，只有把它淘汰，一了百了。

A chronic respiratory disease such as sneezing, nasal serous or purulent secretions, these slow respiratory disease generally have large scale breed, but the number and degree of severity is different, it is extremely difficult to cure, hi this method I basically have used to relieve symptoms can not eradicate, to avoid unnecessary consumption and human time money lingering chronic infectious, only to have it out, One finished, all is finished.

二、繁殖性能不好：连续三次配不上种的；连续两胎产仔５只以下的；连续两窝断奶仔兔５只以下的，流产后子宫有慢性炎症长期排出脓性分泌物的；发生过乳房炎后乳腺增生乳头堵塞两个以上的；不在产箱产仔的；需要人强制喂奶的；有食仔癖排除其它原因后无法纠正的等。

Two, the reproductive performance is not good: three times in a row is not worthy of a continuous two; litter size 5 below; continuous two litters weaned rabbits 5 below the uterus after abortion with chronic inflammation long-term discharge of purulent secretions occurred after breast hyperplasia mastitis; more than two nipple plug in; the litter box production needs; people forced feeding; with the cannibalistic infanticide to exclude other causes can not be corrected.

三、两年半以上的老母兔除个别极优秀的留下外其余全部淘汰。

Three years old, more than half of the rabbits except individual leave excellent except all out.

四、所产仔兔有畸形的如八字脚等。

Four, the pups have deformity such as eight feet.
