        養兔是一種經濟效益高的養殖業,但是在養兔過程中經常會出現化胎的現象,一旦管理不當易死亡。那么巨型安哥拉兔生產出現化胎的原因?下面長毛兔廠家為您講解。
        Raising rabbits is a kind of breeding industry with high economic benefits. However, in the process of raising rabbits, the phenomenon of embryo formation often occurs, and it is easy to die if the management is not proper. So what is the reason for the birth of giant Angora rabbits? The following is an explanation for you by the long haired rabbit manufacturer.
        (一)環境溫度過高
        (1) The ambient temperature is too high
        妊娠期飼養室溫度、濕度過高,特別是溫度超出了臨界溫度時,巨型安哥拉兔母兔抵抗力下降,出現化胎現象。
        When the temperature and humidity of the feeding room during pregnancy are too high, especially when the temperature exceeds the critical temperature, the resistance of the giant Angora rabbit mother rabbit decreases and the phenomenon of embryo formation occurs.
        (二)巨型安哥拉兔母兔消瘦
        (2) Giant Angora rabbit, female rabbit emaciated
        巨型安哥拉兔母兔消瘦體質弱,子宮黏膜薄,營養不足,胚胎著床后因營養供給不是而導致化胎。
        The giant Angora rabbit mother rabbit is thin and weak, with thin uterine mucosa and insufficient nutrition. After the implantation of the embryo, the nutrition supply is not enough to cause the embryo to change.
        (三)受精卵生命力弱
        (3) The vitality of fertilized eggs is weak
        生命力較弱的精、卵結合后,胚胎發育到一定階段就終止發育。在生產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,都容易出現化胎性空懷。
        After the sperm and egg with weak vitality combine, the development of the embryo is terminated at a certain stage. In the production of middle-aged male rabbits with old female rabbits, young male rabbits with old female rabbits, old male rabbits with young female rabbits, young male rabbits with young female rabbits, etc., it is easy to have fetal emptiness.
        (四)生殖道器質性病變
        (4) Organic lesions of genital tract
        巨型安哥拉兔母兔妊娠期子宮,陰道發生炎性病變,危及子宮黏膜,出現化胎現象。
        Inflammatory lesions occurred in the uterus and vagina of giant Angora rabbits during pregnancy, endangering the uterine mucosa and causing fetalization.

        (五)妊娠期飼發霉變質飼料
        (5) Feed moldy and deteriorated feed during pregnancy
        有些飼養場給妊娠母兔飼喂發霉變質的飼料、草粉等,引起母兔腹瀉,導致體質下降而出現化胎。
        Some feeding farms feed the pregnant female rabbits with moldy and deteriorated feed, grass powder, etc., which causes the female rabbits to have diarrhea, resulting in the physical decline and the emergence of fetuses.
        (六)飼料中長期缺乏與生育有關的維生素
        (6) There is a long-term lack of vitamins related to fertility in the feed
        飼養時常年不喂青綠飼料,以干草粉補充纖維時又不重視補充維生素,特別是不重視補充維生素A、維生素E、維生紊B1,等及微量元素,導致化胎。
        When feeding, they often do not feed green fodder every year, and do not pay attention to the supplementation of vitamins when supplementing fiber with hay powder, especially the supplementation of vitamin A, vitamin E, vitamin B1, etc. and trace elements, resulting in the formation of fetuses.
