1、母兔配种年龄
1. Mating age of female rabbit
母兔初次配种,年龄不宜过早,以5~7月龄进行初配为宜,小型兔5月龄且体重达到5斤以上时进行初配,中型兔6月龄且体重达到7斤以上时进行初配,大型兔7月龄且体重达到8斤以上时进行初配。另外初配母兔不宜采用体型较大的公兔配种,应采用不同的公兔进行复配。
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、配种前调理
2. Pre breeding conditioning
夏季气温高易造成兔子采食量大幅下降,膘情较差,因此可先对母兔进行调理之后再进行配种。可适当增加饲料及青绿多汁饲料喂量,给母兔免疫兔出血症败血症(兔瘟)、巴氏杆菌病等疫苗,在母兔空怀期注射疫苗更为安全且免疫效果好,后可在兔子饮水中添加电解多维,并在饲料中添加增蛋散,可以有效增强兔子的繁殖能力。
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、母兔配种时间
3. Mating time of female rabbit
秋天白天温度高,而公兔只有在25℃以下才有较高的活力和良好的精液质量,母兔才有较高的繁殖力,因此应在早晚凉爽时进行配种,这样才有良好的配种受胎率。另外避开饲喂时间段,以免公兔和母兔互相抢食而拒绝配种。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、母兔发情鉴定
4. Oestrus identification of female rabbits
母兔发情周期为8~15天,发情持续期为2~3天,整个发情周期可分为早期、中期及末期,未发情母兔水门可视粘膜为白色,发情早期可视粘膜为粉红色,发情中期可视粘膜为大红色,发情末期可视粘膜为紫红色,以发情中期配种受孕率高。
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.
长毛兔
5、合理安排配种
5. Reasonably arrange breeding
长毛兔母兔发情中期进行配种,一般多将母兔抓入公兔笼内进行配种,若母兔不接受配种,可先将母兔抓回原笼10~20分钟待原公兔气味消失后,再抓入另一只公兔笼内进行配种。为了保证良好的配种受胎率可进行复配,母兔次配种后20~30分钟再用另一只公兔进行配种,或者母兔次配种后6~8小时再用同一只公兔配种一次,前者由于血缘关系不清一般只能用作生产商品兔。
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、加强饲养管理
6. Strengthen feeding management
母兔配种后应加强饲养管理,以免母兔出现流产,及增加产出仔兔质量。兔子生性胆怯,对一切惊扰的应激反应比较大,惊吓、抓兔、摸胎等均可能造成母兔流产、死胎,因此母兔应尽可能避免惊吓,当需要抓兔、摸胎时动作一定轻缓。其次,母兔怀孕后需要充足的营养来满足自身及胎儿生长发育的需要,应适当增加饲料和青绿多汁饲料喂量才可以;做好兔舍内的卫生消毒工作,粪污及时清理并定期进行消毒,加强通风换气以降低兔舍内的湿度、粉尘等。
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.
