1、母兔配種年齡
1. Mating age of female rabbit
母兔初次配種，年齡不宜過早，以5~7月齡進行初配為宜，小型兔5月齡且體重達到5斤以上時進行初配，中型兔6月齡且體重達到7斤以上時進行初配，大型兔7月齡且體重達到8斤以上時進行初配。另外初配母兔不宜采用體型較大的公兔配種，應采用不同的公兔進行復配。
For the first breeding of female rabbits, the age should not be too early. It is appropriate to carry out the initial mating at the age of 5 to 7 months. The initial mating should be carried out when the small rabbit is 5 months old and weighs more than 5 kg. The initial mating should be carried out when the medium rabbit is 6 months old and weighs more than 7 kg. The initial mating should be carried out when the large rabbit is 7 months old and weighs more than 8 kg. In addition, male rabbits with larger body size should not be used for initial mating of female rabbits, and different male rabbits should be used for compounding.
2、配種前調理
2. Pre breeding conditioning
夏季氣溫高易造成兔子采食量大幅下降，膘情較差，因此可先對母兔進行調理之后再進行配種。可適當增加飼料及青綠多汁飼料喂量，給母兔免疫兔出血癥敗血癥(兔瘟)、巴氏桿菌病等疫苗，在母兔空懷期注射疫苗更為且免疫效果好，后可在兔子飲水中添加電解多維，并在飼料中添加增蛋散，可以有效增強兔子的繁殖能力。
The high temperature in summer is likely to cause a sharp decline in rabbit feed intake and poor fat. Therefore, the female rabbit can be conditioned before breeding. The feeding amount of feed and green and juicy feed can be appropriately increased to immunize the female rabbits against rabbit hemorrhagic sepsis (rabbit plague), Pasteurellosis and other vaccines. It is safer and has good immune effect to inject the vaccine into the female rabbits during the empty period. After that, the electrolytic multidimensional can be added to the rabbits' drinking water, and zenggen powder can be added to the feed, which can effectively enhance the reproductive ability of the rabbits.
3、母兔配種時間
3. Mating time of female rabbit
秋天白天溫度高，而公兔只有在25℃以下才有較高的活力和良好的精液質量，母兔才有較高的繁殖力，因此應在早晚涼爽時進行配種，這樣才有良好的配種受胎率。另外避開飼喂時間段，以免公兔和母兔互相搶食而拒絕配種。家兔秋繁管理
In autumn, the daytime temperature is high, but only when the temperature is below 25 ℃ can male rabbits have high vitality and good semen quality, and female rabbits have high fertility. Therefore, breeding should be carried out in the morning and evening when it is cool, so as to have a good breeding conception rate. In addition, avoid the feeding period, so as to avoid the male rabbit and the female rabbit competing for food and refusing to breed. Autumn breeding management of rabbits
4、母兔發(fā)情鑒定
4. Oestrus identification of female rabbits
母兔發(fā)情周期為8~15天，發(fā)情持續(xù)期為2~3天，整個發(fā)情周期可分為早期、中期及末期，未發(fā)情母兔水門可視粘膜為白色，發(fā)情早期可視粘膜為粉紅色，發(fā)情中期可視粘膜為大紅色，發(fā)情末期可視粘膜為紫紅色，以發(fā)情中期配種受孕率高。
The oestrus cycle of female rabbits is 8-15 days, and the oestrus duration is 2-3 days. The whole oestrus cycle can be divided into early, middle and late stages. The Watergate visible mucosa of non oestrus female rabbits is white, the early oestrus visible mucosa is pink, the middle oestrus visible mucosa is bright red, and the late oestrus visible mucosa is purplish red. The pregnancy rate of mating in the middle oestrus is high.
5、合理安排配種
5. Reasonably arrange breeding
長毛兔母兔發(fā)情中期進行配種，一般多將母兔抓入公兔籠內進行配種，若母兔不接受配種，可先將母兔抓回原籠10~20分鐘待原公兔氣味消失后，再抓入另一只公兔籠內進行配種。為了保證良好的配種受胎率可進行復配，母兔次配種后20~30分鐘再用另一只公兔進行配種，或者母兔次配種后6~8小時再用同一只公兔配種一次，前者由于血緣關系不清一般只能用作生產商品兔。
Long haired rabbits are bred in the middle of estrus. Generally, the female rabbit is usually caught in the male rabbit cage for breeding. If the female rabbit does not accept breeding, the female rabbit can be caught back in the original cage for 10~20 minutes. After the smell of the original male rabbit disappears, the female rabbit can be caught in another male rabbit cage for breeding. In order to ensure a good mating conception rate, the female rabbit can be mated with another male rabbit 20~30 minutes after the first mating, or with the same male rabbit 6~8 hours after the first mating. The former can only be used to produce commercial rabbits due to unclear blood relationship.
6、加強飼養(yǎng)管理
6. Strengthen feeding management
母兔配種后應加強飼養(yǎng)管理，以免母兔出現(xiàn)流產，及增加產出仔兔質量。兔子生性膽怯，對一切驚擾的應激反應比較大，驚嚇、抓兔、摸胎等均可能造成母兔流產、死胎，因此母兔應盡可能避免驚嚇，當需要抓兔、摸胎時動作一定輕緩。其次，母兔懷孕后需要充足的營養(yǎng)來滿足自身及胎兒生長發(fā)育的需要，應適當增加飼料和青綠多汁飼料喂量才可以;做好兔舍內的衛(wèi)生工作，糞污及時清理并定期進行，加強通風換氣以降低兔舍內的濕度、粉塵等。
The feeding and management of female rabbits should be strengthened after breeding to avoid abortion of female rabbits and increase the quality of newborn rabbits. Rabbits are naturally timid and have a large stress response to all disturbances. Scaring, grasping and touching the fetus may cause abortion and stillbirth of the mother rabbit. Therefore, the mother rabbit should avoid scaring as much as possible. When it is necessary to grasp the rabbit and touch the fetus, the action must be slow. Secondly, after pregnancy, the female rabbit needs sufficient nutrition to meet the needs of her own and fetal growth and development, and the feeding amount of feed and green juicy feed should be appropriately increased; Do a good job in the sanitation and disinfection of the rabbit house, clean up the feces in time and disinfect regularly, and strengthen the ventilation to reduce the humidity and dust in the rabbit house.
