一、有慢性呼吸道疾病的如打噴嚏，鼻有漿液性或膿性分泌物等，這些慢呼疾病一般規模兔場都有，只是數量的多少和程度的輕重不同而已，要想根治它極難，各位兔友介紹的方法我基本上都用過，緩解癥狀可以，不能根除，為避免人力時間的無謂消耗和藕斷絲連的慢性傳染，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：連續三次配不上種的；連續兩胎產仔５只以下的；連續兩窩斷奶仔兔５只以下的，流產后子宮有慢性炎癥長期排出膿性分泌物的；發生過乳房炎后乳腺增生乳頭堵塞兩個以上的；不在產箱產仔的；需要人強制喂奶的；有食仔癖排除其它原因后無法糾正的等。
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.
