    在(zai)養兔(tu)(tu)(tu)(tu)生(sheng)(sheng)產(chan)中(zhong)，往(wang)往(wang)會遇到(dao)有的(de)母兔(tu)(tu)(tu)(tu)在(zai)交(jiao)配后１６～１８天(tian)出現臨產(chan)行為，母兔(tu)(tu)(tu)(tu)的(de)乳房發生(sheng)(sheng)膨(peng)脹，并開始叼(diao)草拉(la)毛作窩，但等了(le)幾天(tian)并無仔兔(tu)(tu)(tu)(tu)產(chan)出，這種現象是假(jia)孕。假(jia)孕不(bu)但耽誤繁殖仔兔(tu)(tu)(tu)(tu)，而且(qie)還會影響和消(xiao)耗母兔(tu)(tu)(tu)(tu)的(de)體力，造成經濟損失。為了(le)減少或杜絕假(jia)孕發生(sheng)(sheng)，可采(cai)取以下措施：

　　１．對繁殖(zhi)種(zhong)兔(tu)(tu)，建(jian)譜立系(xi)首(shou)先分(fen)組編號，公(gong)兔(tu)(tu)、母兔(tu)(tu)分(fen)別建(jian)立繁殖(zhi)卡(ka)片，使交配、產仔有記錄(lu)，做到近親不配，未發育成熟不配，換毛高(gao)峰期和風雨雪炎熱天氣(qi)不配。

　　２．采取重(zhong)復配(pei)(pei)(pei)種(zhong)(zhong)(zhong)和(he)雙(shuang)重(zhong)配(pei)(pei)(pei)種(zhong)(zhong)(zhong)的方(fang)法，一般種(zhong)(zhong)(zhong)兔(tu)場(chang)采用(yong)重(zhong)復配(pei)(pei)(pei)種(zhong)(zhong)(zhong)法，即在(zai)第(di)１次配(pei)(pei)(pei)種(zhong)(zhong)(zhong)５～６小(xiao)時(shi)再用(yong)同(tong)１只(zhi)種(zhong)(zhong)(zhong)公兔(tu)進行第(di)２次交(jiao)配(pei)(pei)(pei)。商(shang)品(pin)兔(tu)場(chang)可采用(yong)雙(shuang)重(zhong)配(pei)(pei)(pei)種(zhong)(zhong)(zhong)法，即在(zai)第(di)１只(zhi)公兔(tu)交(jiao)配(pei)(pei)(pei)后過１５分鐘再用(yong)另(ling)一只(zhi)種(zhong)(zhong)(zhong)公兔(tu)交(jiao)配(pei)(pei)(pei)１次。長期沒用(yong)的種(zhong)(zhong)(zhong)公兔(tu)，必須在(zai)配(pei)(pei)(pei)種(zhong)(zhong)(zhong)后的６～８小(xiao)時(shi)內再進行復配(pei)(pei)(pei)。

　　３．加(jia)強飼養管理，搞好(hao)清潔(jie)衛(wei)生和消毒工作，對種(zhong)兔(tu)(tu)(tu)增加(jia)運動(dong)時間，防止(zhi)過度(du)肥胖。不要隨意捕捉(zhuo)、撫摸母(mu)(mu)(mu)兔(tu)(tu)(tu)。除促(cu)使(shi)母(mu)(mu)(mu)兔(tu)(tu)(tu)發情(qing)外，一般(ban)不讓(rang)試情(qing)公兔(tu)(tu)(tu)隨意追(zhui)逐爬(pa)跨(kua)母(mu)(mu)(mu)兔(tu)(tu)(tu)。種(zhong)母(mu)(mu)(mu)兔(tu)(tu)(tu)應分籠飼養，保持(chi)一兔(tu)(tu)(tu)一籠，防止(zhi)有的母(mu)(mu)(mu)兔(tu)(tu)(tu)發情(qing)后(hou)爬(pa)跨(kua)其(qi)他(ta)母(mu)(mu)(mu)兔(tu)(tu)(tu)。

　　４．母(mu)兔(tu)交配后(hou)５～７天進(jin)行(xing)復配，１０～１２天進(jin)行(xing)摸胎(tai)檢查，以便及時(shi)補配，防止不孕(yun)或假孕(yun)
