1、 Choose seeds correctly

　　不同用途家兔的繁殖力存在明顯差異。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。在育種品種的田間選育初期，應注重生產性能(生長率、毛產量等)，生殖性能應作為重要內容

　　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

　　二是全價供應，飲食均衡

　　Second, full price supply and balanced diet

　　為種兔提供全價、均衡營養和保持良好的身體狀況是提高生育力的重要措施。目前,大多數兔子生產商準備膳食能量、粗纖維可以滿足需求的兔子,但是等微量元素缺乏或不合理使用,導致女兔子不發情,不排卵,受孕率低,即使懷孕,胎兒死亡率、畸形率、流產率也很高,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，增加母兔在群體中的比例

　　Third, increase the proportion of female rabbits in the population

　　3歲以上的老兔子出生率低，幼兔體弱多病，死亡率高。老齡兔在家兔種群中所占比例較大，是部分養兔場年肥力較低的重要原因。及時淘汰老兔子，保持年輕和成熟雌性的優勢，可以提高兔子的繁殖能力。因此，每年必須選擇和培養足夠的備用兔子作為補充。

　　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，改進育種技術

　　Fourth, improve breeding technology

　　兔媽媽發情時，繁殖受孕率高，所以要經常對兔進行發情檢查，及時發現，及時繁殖。交配可以采用重復、重復、血液匹配等自然交配方式，有條件的也可以采用人工授精技術。對長期不發情的個體，除了加強飼養治理外，還要用物理或化學方法進行催情劑。

　　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.

　　科學地控制光線和溫度

　　Scientific control of light and temperature

　　冬季、春季光照時間延長，補充光照每天16小時，有利于兔媽媽發情。各種降溫措施在夏季高溫季節應采取減少高溫的不利影響在繁殖兔子,避免在夏季和縮短懷孕,可有效增加女性兔子”年度生殖胎兒,以提高生育的人口。降低溫度的方法有:在兔房前種植藤本植物;增加兔房通風量。據報道，每100公斤種兔日糧中添加10克維生素C粉，可增強雌雄兔的耐熱性，提高受孕率，增加子代數量。此外，根據埃及的相關報道，在環境溫度達到37℃，濕度為42%的情況下，每公斤飼料中添加35毫克鋅，使母兔的受孕率提高了13.1%，產仔數增加了1.3窩。

　　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.
