一、受配母兔年龄选择
One, with female rabbits by age
母兔繁殖年龄一般出生后养到6月龄以上，体重在4公斤左右就可以进入配种繁殖，根据饲养实践证明，上胎比例青年兔要高于成年母兔，以后配种上胎率较低，一般秋、冬季节受孕率在25%左右，春季在45%之间，如果在一周岁内的青年母兔秋、冬季节受孕率在60%左右，春季在80%以上，所以我们在选择受配母兔的年龄上应在8月龄至2周岁以内的母兔为最佳，对3周岁的母兔要逐步淘汰或进入产毛群体。
Mother rabbit breeding age after birth in June raised to age, body weight 4 kg can enter the breeding, feeding on according to the practice, the proportion of young rabbit fetus is higher than that of adult female rabbits, after mating on pregnancy rate is low, generally fall, winter conception rate at around 25%, in the spring of 45%, if the age of young female rabbit autumn, winter conception rate at around 60%, in the spring of 80%, so we are with the mother rabbit age in August age to 2 years of age within the mother rabbit is the best choice, to 3 years old female rabbit to the phasing out of or into the wool group.
二、配种前要做好母兔检查关

为提高母兔上胎率，尽是做到不浪费配种季节，繁殖前选择好配种母兔是至关重要的一环，必须要把握好3关；①空怀母兔检查关；用手摸母兔下腹部子宫有否肿涨发炎，生死器及外阴部有否炎症，这种兔是常配不孕的，凡此种症状的兔待治好后再配种。②剪毛关；配种母兔身毛不能留养过长，要求离配种前20天把身毛剪去，这样不影响公兔配种，使母兔举尾相迎来提高上胎机会。③母兔抚养关；对繁殖前不论任何雌兔一概而言全部配种，要检查母兔乳头有否齐全，正常兔乳头在4对以上，有的雌兔在剪毛时已剪掉乳头不能哺乳；要检查原来母兔有否患过严重乳房炎，要掌握原来母性好坏，有否有吃食仔兔习惯等对以上不符合要求的全部不能进入配种。
As the birth rate in female rabbits, all do not waste the breeding season, pre breeding selection breeding female rabbit is a very important link, must grasp 3; the nonpregnant female rabbit examination; touch the mother rabbit abdomen and uterus has inflammation and swelling, and whether there is inflammation of vulva the rabbit is often, sterility, these symptoms of rabbit to be cured after mating. The shearing off; breeding female rabbit body hair can't keep long, requirements from the mating of 20 days before the body hair cut, so that does not affect the male rabbit mating, the female rabbit tail phase in improving on fetal the chance. The mother rabbit raising; the pre reproductive regardless of any female rabbits all all breeding, to check the nipples are not complete, normal rabbit papillary in 4 of the above, some female rabbits in wool has cut nipple can not breast-feeding; to check the original female rabbits have you suffered from severe mastitis, to master the original maternal quality was there a young rabbit, eating habits on the do not meet all requirements to enter the breeding can not.
三、母兔要配种

根据我市实际，长毛兔配种季节从农历的9月份起到次年的5月份止9个月为繁殖季节，6－8月3个月为夏季高温季节应停止母兔繁殖，一般情况一年一只母兔可繁小兔3－4胎，兔子怀孕期一个月，每月有二次排卵，兔子发情有三个方面；一是自然发情每月二次，二是引诱发情，通过公母兔关在一起让公兔自行爬跨促使发情，三是可用促排3号或绒毛膜激素注射后刺激发情。配种前要检查母兔有否发情，母兔外阴部红肿增大则说明已发情，一般雌兔发情持续期3天左右，以外阴部经转紫配种最适明，上胎比率较高。母兔配种后在12天左右，要及时摸胎检查上胎率，对不上胎母兔继续进行重配。
According to the actual city, Angora rabbit breeding season from the September to May only 9 months for the breeding season, from 6 to August 3 months for the summer high temperature season should stop mother rabbit breeding, generally a year a mother rabbit breeding rabbit 3 - 4 fetal, rabbit pregnant a month two times per month, ovulation, the rabbit in three aspects; one is the natural estrus two times a month, two was to induce estrus, close together let male rabbit creeping cross promote estrus by male and female rabbits, three is available to 3 or chorionic hormone stimulated after injection of estrus. Before hybridization to check whether the estrus female rabbit, rabbit vulvar redness increases is already estrus, generally the female rabbit estrus duration of 3 days, the genitals by turn purple breeding optimal Ming, higher ratio of tire. Mother rabbit after mating in about 12 days, to touch the pregnancy rate of fetal examination, not on fetal rabbit continued reassortment.
四、母兔不能养得过肥过瘦

注意对空怀母兔的饲养管理，掌握兔子体膘，不能养过肥过瘦，特别是养得过肥，引起母兔子宫增厚，扰乱排卵规律，大大地降低受胎率，同时经常会出现假孕现象，假孕兔配种后20多天会做巢、拉毛、手去捉摸母兔 会发出咕咕叫声，症状与正常受孕母兔相似，用手去摸胎都是空孕，对已经养得过肥的母兔要减少饲喂日量，降低饲料营养，多喂粗纤维饲料或添加维生素A、E的药物，增加青饲料的补充，如胡萝卜、黑麦草、野生草料等对兔提高上胎率都有好处。
Pay attention to feeding and management of nonpregnant female rabbit, rabbit fat master, can not raise too fat too thin, especially to raise too fat, cause the mother rabbit uterine thickening, disrupt ovulation, greatly reduce the fertility rate, at the same time, often appear in pseudopregnant phenomenon, pseudopregnant rabbit breeding after 20 days will do nest, napping, hand to grasp females emit cooing, symptoms and normal pregnant female rabbits similar, hand to touch the fetus is empty of pregnant, had kept too fat to reduce the amount of female rabbits fed diet decreased feed nutrition, medicine, feed more roughage or add vitamin A, E, increasing added green feed, such as carrots, ryegrass, wild forage on rabbit increase pregnancy rate are good.
五、要保证公兔有效精子
Five, to ensure effective sperm of male rabbit
母兔上胎最重要的关键是公兔精子是否有效，一般采用体配的户开始都会带来一定盲目性，要求配种前对公兔精子活率用显微镜放大400倍进行检查，在显微镜中观察精子密度高，活力强，呈直线运动，有效精子在70%以上可投入使用，如果精子原地摆动，转圈、双头双尾属于无效精子不能投入配种。
The most important key tire mother rabbit is the male rabbit sperm is effective, generally use the body with the users will begin to bring certain blindness before mating, requirements on the male rabbits live rate of sperm with the microscope magnified 400 times were examined under the microscope, the sperm density, vigor, in a straight line, effective sperm put into use in 70% above, if the sperm autochthonous swing, circle, double tail to void the sperm can not be put into service.
