I. How to improve the winter reproduction rate of rabbits
1. Strictly screen breeding rabbits. Owners should choose female rabbits that are healthy and disease-free, have strong sexual desire, good motherhood and well-developed reproductive organs to participate in breeding. In addition, it is best to select from the 3rd to the 5th litter of excellent female rabbits with more than 4 pairs of nipples. For female rabbits with small litter size, low conception rate, poor motherhood, and poor lactation performance, it is not suitable for them to be bred. Generally, the suitable breeding age for rabbits is 1 to 3 years old. For rabbits over 3 years old, unless they are breeding rabbits with particularly good body condition, the rest are not suitable for breeding.
2. Strengthen the feeding and management of rabbits. After the owner selects the breeding rabbit, he must pay attention to adjusting the feeding and management of the rabbit before and after breeding. The breeding rabbit should be fed with full-price feed to meet all the nutritional needs of the breeding rabbit and reduce the occurrence of abortion and embryo death of the female rabbit. Committed to improving the breeding capacity of breeding rabbits. Note: The female rabbit’s long-term feeding of a single feed or unbalanced feed, or excessive nutritional supplementation will seriously affect the female rabbit’s reproductive ability.
In addition, improper management will also affect the breeding ability of breeding rabbits, and even lead to infertility of breeding rabbits. For example, the owner usually needs to pay attention to avoid the sudden sound around the rabbit house, which will cause the rabbit group to panic, cause the pregnant rabbit to abort or cause the female rabbit’s libido to decrease.
3. Pay attention to timely breeding. The owner needs to reasonably arrange the mating season and mating time of the breeding rabbits according to the climatic conditions and thermal insulation and cooling facilities of the breeding environment. For example, winter breeding of rabbits should provide more green feed for rabbits, and do a good job of preventing cold and keeping warm in time for rabbits. Under the condition that the female rabbit’s physique is healthy and the conditions are sufficient, the rabbit can be allowed to breed 1~2 litters. Generally, rabbits are more suitable for breeding in spring and autumn. The conception rate in spring and autumn is higher, and the number of litter is more. If you let the rabbit breed in winter, you must control the temperature of the rabbit house, which is the guarantee of whether the rabbit can reproduce normally.
The best mating time of female rabbits is in the middle and late period of estrus, when the female rabbit’s genitals are moist and swollen, and the breeding conception rate is the highest. On the contrary, if the female rabbit is bred too early or too late, the effect is not ideal.
