After sexual maturity, the ovaries of female rabbits will mature a batch of follicles every other period of time, making them estrous. If they cannot ovulate without the stimulation of mating, these mature follicles will gradually shrink and degenerate under the synergistic effect of estrogen and progesterone. Later, the new follicles began to mature and oestrus, so that the female rabbit was always in the state of periodic oestrus. The heat of a cycle starts from the beginning of the previous heat to the beginning of the next heat. The estrous cycle of female rabbit is not fixed, and it is easy to be affected by the external environment, such as feeding, light, nutrition, weather, male rabbit effect, etc. Generally speaking, it is common for females to have estrus after childbirth and weaning. During lactation, oestrus is affected by lactation intensity and nutritional level. The estrus cycle of lactation is about 5-7 days, and each estrus lasts about 48 hours. Female rabbits should choose to mate in the breeding period, with a higher pregnancy rate; if female rabbits do not have estrus, forced mating, with a lower pregnancy rate. According to incomplete clinical statistics, the pregnancy rate of forced mating is between 10-50%.

　　在实际生产中，经常会有农场问，长毛兔产后多少天配种好？根据我的经验，现在将在实际生产中用到的养殖模式如下，希望对广大农场有所帮助:

　　In the actual production, often there will be farms to ask, how many days after the birth of long hair rabbit breeding good? According to my experience, the breeding mode that will be used in the actual production is as follows, hoping to be helpful to the vast farms:

　　一、血配

　　1、 Blood match

　　“血配”又称频密繁殖，即在母兔交配完成后3天内分娩。

　　"Blood matching" is also called frequency dense reproduction, which means that the female rabbits give birth within 3 days after mating.

　　优点:1、检查情况容易，兔产后发情普遍，不需要光照或激素刺激;2. 轮胎年利用率高。缺点:1。这种交配方式，哺乳和怀孕可以同时发生，很容易使母兔体重下降，身体变差;2. 2. 泌乳对生殖性能有负面影响，导致产仔数减少;3.母兔淘汰率高。

　　Advantages: 1. It is easy to check the condition, and the oestrus is common in rabbits after childbirth, which does not need light or hormone stimulation; 2. The annual utilization rate of tires is high. Disadvantages: 1. This kind of mating mode, lactation and pregnancy can occur at the same time, it is easy to make the female rabbit lose weight and become worse; 2. 2. lactation has a negative impact on the reproductive performance, leading to a decrease in the number of offspring; 3. the elimination rate of female rabbit is high.

　　如果你想使用这种方法，你必须满足以下要求:2. 兔妈妈的材料应该是高档的，含有足够的能量和蛋白质。3.储备的兔妈妈可以自己饲养。

　　If you want to use this method, you must meet the following requirements: 2. The material of the mother rabbit should be high-grade, with enough energy and protein. 3. The reserve mother rabbit can be raised by herself.

　　二、产后12天匹配

　　2、 12 day postpartum matching

　　这种方法也被称为半频繁繁殖，即在雌性兔子分娩后12天内，在交配完成之前和之后。有的兔场在产后7-9天，有的兔场在产后18天，均属于半频密集繁殖，一般按兔群质量选择。这种养殖方式，是目前规模化养兔场使用更多的养殖方式，也是笔者的主要养殖方式。

　　This method is also known as semi frequent reproduction, i.e. within 12 days after delivery, before and after mating. Some rabbit farms are 7-9 days postpartum, and some are 18 days postpartum. They are all half frequency intensive reproduction, generally selected according to the quality of rabbit population. This kind of breeding mode is the most widely used one in large-scale rabbit farms, and also the main breeding mode of the author.

　　优点:1.在这种交配模式下，雌兔的年出生数和产仔数是理想的。2、幼兔可在35天内断奶，保证断奶重量和断奶成活率。缺点:兔妈妈在哺乳期发情不固定，需要反复检查情况，工作量大。

　　Advantages: 1. In this mating mode, the annual birth and litter size of female rabbits are ideal. 2. Young rabbits can be weaned within 35 days to ensure weaning weight and survival rate. Disadvantages: the mother rabbit's oestrus is not fixed during the lactation period, which needs to be checked repeatedly, and the workload is heavy.

　　建议:采用这种配种方式来养殖兔场，可以配合使用灯光来激发热量，减少查房的工作量，提高立柱的均匀性。

　　Suggestion: using this kind of breeding method to breed rabbit farm, we can use light to stimulate heat, reduce the workload of rounds, and improve the uniformity of columns.

　　三、断奶后比赛

　　3、 Post weaning competition

　　断奶后，饲养正常，即断奶后3-5天。

　　After weaning, feeding is normal, that is, 3-5 days after weaning.

　　优点:1。兔宝宝断奶后，兔妈妈发情规律强，不需要光照或激素刺激，易掌握;2. 信息核查工作量相对较小;3.兔妈妈体质好，利用时间长，淘汰率低;4、幼兔断奶时间不限，确保幼兔断奶体重和成活率;4、兔妈妈对饲料的要求不高，可以和商品兔一起吃一种材料(注意多放点花生)，管理简单。缺点:每年轮胎数量少。

　　Advantages: 1. After weaning the baby rabbit, the mother rabbit has a strong estrus law, which is easy to master without light or hormone stimulation; 2. The workload of information verification is relatively small; 3. The mother rabbit has a good constitution, a long utilization time, and a low elimination rate; 4. The weaning time of the baby rabbit is unlimited to ensure the weaning weight and survival rate of the baby rabbit; 4. The mother rabbit does not have high requirements for feed. She can eat a kind of material together with the commercial rabbit (pay attention to put more peanuts), and the management is simple. Disadvantages: fewer tires per year.
