⑴ 根據(jù)母兔發(fā)情表現(xiàn)確定配種時(shí)間。肉母兔的發(fā)情周期變化較大，一般在8-15天，發(fā)情期一般是3天左右。發(fā)情表現(xiàn)為舉止不安，食欲減退，常以前肢扒箱或后肢"頓足"，有時(shí)還有銜草做窩現(xiàn)象，外陰部潮濕紅腫。整個(gè)發(fā)情期分為前期、中期、后期，其判斷主要看陰戶的變化情況：發(fā)情前期變得較濕潤(rùn)、微腫、粉紅色；中期濕潤(rùn)、腫大、呈大紅色（俗稱老紅）；后期濕潤(rùn)、腫大、紫黑色。更佳的配種時(shí)間是發(fā)情的中后期。
To determine the mating time according to the female rabbit estrus expression. Mother rabbit meat estrous cycle changes larger, generally in the 8-15 days, the estrous period is generally 3 days. Estrus behavior manner discomfort, loss of appetite, often in the forelimb or hindlimb grilled box "stomp", and sometimes Pyrolae nest phenomenon, vulva damp redness. The entire season is divided into prophase, metaphase, anaphase, the judgment mainly to see the changes: vulva proestrus become more moist, slightly swollen, pink; mid moist, swelling, a big red (commonly known as the old red); the late wet, swelling, purple black. The best time is the late estrus in breeding.
⑵ 試情法確定交配時(shí)期。把母兔放入公兔欄內(nèi)，當(dāng)公兔追逐爬跨時(shí)，如母兔作接受交配姿勢(shì)，說(shuō)明母兔已發(fā)情，即可進(jìn)行配種。否則，未發(fā)情，不能交配。
The determination of the mating period test conditions the method. The mother rabbit into the male rabbit column, when the male rabbit chase intromission, such as mother rabbit accepts the mating posture, illustrate the mother rabbit has estrus, can be breeding. Otherwise, not in estrus, not mating.
⑶ 血配。即母兔產(chǎn)仔后1-2天進(jìn)行配種。
The blood distribution. That the mother rabbit litter performed 1-2 days after mating.
