1. Mating age of female rabbit
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. Pre breeding conditioning
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. Mating time of female rabbit
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. Oestrus identification of female rabbits
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. Reasonably arrange breeding
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. Strengthen feeding management
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.
