1、 Choose seeds correctly

　　不同用途家兔的繁殖力存在明显差异。例如，有肉、有皮、有肉的兔子的繁殖力一般高于有皮、有毛的兔子。在育种品种的田间选育初期，应注重生产性能(生长率、毛产量等)，生殖性能应作为重要内容

　　There were significant differences in the fecundity of rabbits for different purposes. For example, the fecundity of rabbits with meat, skin and meat is generally higher than that of rabbits with skin and hair. In the early stage of field breeding, production performance (growth rate, gross yield, etc.) should be emphasized, and reproductive performance should be taken as an important content

　　二是全价供应，饮食均衡

　　Second, full price supply and balanced diet

　　为种兔提供全价、均衡营养和保持良好的身体状况是提高生育力的重要措施。目前,大多数兔子生产商准备膳食能量、粗纤维可以满足需求的兔子,但是等微量元素缺乏或不合理使用,导致女兔子不发情,不排卵,受孕率低,即使怀孕,胎儿死亡率、畸形率、流产率也很高,男兔子性欲下降,繁殖能力很差。

　　Providing full price, balanced nutrition and keeping good physical condition for breeding rabbits are important measures to improve fertility. At present, most rabbit manufacturers prepare rabbits with dietary energy and crude fiber that can meet the needs, but the lack or unreasonable use of trace elements such as trace elements leads to female rabbits' non estrus, non ovulation and low pregnancy rate. Even if pregnant, the fetal mortality, deformity rate and abortion rate are also very high. The sexual desire of male rabbits decreases and their reproductive capacity is very poor.

　　第三，增加母兔在群体中的比例

　　Third, increase the proportion of female rabbits in the population

　　3岁以上的老兔子出生率低，幼兔体弱多病，死亡率高。老龄兔在家兔种群中所占比例较大，是部分养兔场年肥力较低的重要原因。及时淘汰老兔子，保持年轻和成熟雌性的优势，可以提高兔子的繁殖能力。因此，每年必须选择和培养足够的备用兔子作为补充。

　　The birth rate of the old rabbits over 3 years old is low, the young rabbits are weak and sickly, and the mortality rate is high. The large proportion of aged rabbits in the domestic rabbit population is an important reason for the low annual fertility of some rabbit farms. To eliminate old rabbits in time and maintain the absolute advantage of young and mature females can improve the reproductive capacity of rabbits. Therefore, it is necessary to select and cultivate enough spare rabbits as a supplement every year.

　　第四，改进育种技术

　　Fourth, improve breeding technology

　　兔妈妈发情时，繁殖受孕率高，所以要经常对兔进行发情检查，及时发现，及时繁殖。交配可以采用重复、重复、血液匹配等自然交配方式，有条件的也可以采用人工授精技术。对长期不发情的个体，除了加强饲养治理外，还要用物理或化学方法进行催情剂。

　　When the mother of the rabbit is oestrus, the reproduction and conception rate is high, so it is necessary to check the oestrus of the rabbit frequently, find out in time and breed in time. Natural mating methods such as repetition, repetition and blood matching can be used for mating, and artificial insemination can also be used if conditions permit. For the individuals who do not have oestrus for a long time, in addition to strengthening the feeding management, they should also use physical or chemical methods for oestrogen.

　　科学地控制光线和温度

　　Scientific control of light and temperature

　　冬季、春季光照时间延长，补充光照每天16小时，有利于兔妈妈发情。各种降温措施在夏季高温季节应采取减少高温的不利影响在繁殖兔子,避免在夏季和缩短怀孕,可有效增加女性兔子”年度生殖胎儿,以提高生育的人口。降低温度的方法有:在兔房前种植藤本植物;增加兔房通风量。据报道，每100公斤种兔日粮中添加10克维生素C粉，可增强雌雄兔的耐热性，提高受孕率，增加子代数量。此外，根据埃及的相关报道，在环境温度达到37℃，湿度为42%的情况下，每公斤饲料中添加35毫克锌，使母兔的受孕率提高了13.1%，产仔数增加了1.3窝。

　　In winter and spring, the time of illumination is prolonged, and the supplement of illumination is 16 hours a day, which is beneficial to the estrus of the mother rabbit. All kinds of cooling measures should be taken to reduce the adverse effects of high temperature on breeding rabbits in summer and avoid shortening pregnancy in summer, which can effectively increase the annual reproductive fetus of female rabbits, so as to increase the population of childbearing. The methods to reduce the temperature are: planting vines in front of the rabbit's room; increasing the ventilation of the rabbit's room. It is reported that adding 10 g vitamin C powder to every 100 kg seed rabbit diet can enhance the heat tolerance of male and female rabbits, improve the pregnancy rate and increase the number of offspring. In addition, according to relevant reports in Egypt, when the ambient temperature is 37 ℃ and the humidity is 42%, 35 mg zinc is added to the feed per kilogram, the pregnancy rate of the female rabbit is increased by 13.1%, and the litter size is increased by 1.3.
