一)環(huán)境溫度過(guò)高 妊娠期飼養(yǎng)室溫度、濕度過(guò)高，特別是溫度超出了臨界溫度時(shí)，長(zhǎng)毛兔母兔抵抗力下降，出現(xiàn)化胎現(xiàn)象。
1） When the environmental temperature is too high and the temperature and humidity in the breeding room during pregnancy are too high, especially when the temperature exceeds the critical temperature, the resistance of long haired rabbits decreases and the phenomenon of embryo formation occurs.
二)長(zhǎng)毛兔母兔消瘦 長(zhǎng)毛兔母兔消瘦體質(zhì)弱，子宮黏膜薄，營(yíng)養(yǎng)不足，胚胎著床后因營(yíng)養(yǎng)供給不是而導(dǎo)致化胎。
2） Long haired rabbit mother rabbit is emaciated, with weak physique, thin uterine mucosa, and insufficient nutrition. After embryo implantation, due to insufficient nutrition supply, it leads to embryo metaplasia.
三)受精卵生命力弱 生命力較弱的精、卵結(jié)合后，胚胎發(fā)育到一定階段就終止發(fā)育。在生產(chǎn)中年公兔配老年母兔、青年公兔配老年母兔、老年公兔配青年母兔、青年公兔配青年母兔等，都容易出現(xiàn)化胎性空懷。
3） After the fertilized egg has weak vitality and the sperm and egg combine, the embryo development ends at a certain stage. In the production of middle-aged male rabbits paired with old female rabbits, young male rabbits paired with old female rabbits, old male rabbits paired with young female rabbits, young male rabbits paired with young female rabbits, etc., it is easy to experience fetal emptiness.
四)生殖道器質(zhì)性病變 長(zhǎng)毛兔母兔妊娠期子宮，陰道發(fā)生炎性病變，危及子宮黏膜，出現(xiàn)化胎現(xiàn)象。
4） Organic lesions of the reproductive tract occur in the uterus and vagina of long haired rabbits during pregnancy, posing a threat to the uterine mucosa and leading to the phenomenon of metaplasia.
五)妊娠期飼發(fā)霉變質(zhì)飼料 有些飼養(yǎng)場(chǎng)給妊娠母兔飼喂發(fā)霉變質(zhì)的飼料、草粉等，引起母兔腹瀉，導(dǎo)致體質(zhì)下降而出現(xiàn)化胎。
5） Feeding moldy and spoiled feed during pregnancy. Some farms feed pregnant female rabbits with moldy and spoiled feed, grass powder, etc., which causes diarrhea in the female rabbits and leads to a decrease in physical fitness, leading to the occurrence of miscarriage.
六)飼料中長(zhǎng)期缺乏與生育有關(guān)的維生素 飼養(yǎng)時(shí)常年不喂青綠飼料，以干草粉補(bǔ)充纖維時(shí)又不重視補(bǔ)充維生素，特別是不重視補(bǔ)充維生素A、維生素E、維生紊B1，等及微量元素，導(dǎo)致化胎。
6） Long term lack of vitamins related to fertility in feed often results in the failure to feed green feed every year. When supplementing fiber with hay powder, it is not important to supplement vitamins, especially vitamin A, vitamin E, vitamin B1, and trace elements, leading to miscarriage.
