What is the cause of female rabbit infertility?

Whether pet rabbit or meat rabbit, rabbit has a certain market demand in our country, and now it has a large breeding area in our country. The most important thing in breeding rabbits is to do a good job of keeping species, so the breeding of female rabbits is very important. However, many farmers often find that female rabbits are infertile in the process of breeding. So what is the cause of female rabbit infertility? Let's take a look at it with the editor.

1. Improper feeding

Improper management is the main factor leading to female rabbit infertility, so we should pay attention to control the proportion of nutrition in feed when feeding. To prevent breeding rabbits from getting fat and fat, feed should be reasonably prepared according to the actual situation, and the proportion of concentrate should be adjusted appropriately. The proportion of crude fiber in feed was kept at about 16%. Then focus on postpartum female rabbits, some female rabbits because of more litter size, lactation pressure increased. As a result, the nutrition loss of female rabbits is too large, and the fat condition will also be affected, so we should reasonably increase the amount of feeding and the proportion of nutrition.

2. Lack of technology

When raising rabbits, we must master the time of oestrus of female rabbits. If the time of oestrus of female rabbits can not be determined in time, resulting in improper mating time, it will easily lead to infertility. After the female rabbit is in estrus, the food intake will be significantly reduced, fidgeting, and will lift the tail from time to time. If there is a male rabbit around, it will approach the male rabbit and mate. And we can also observe the vagina of the female rabbit, after estrus, the vagina is moist and swollen. Therefore, we must ensure that there are mature techniques to find the estrus of female rabbits in time and improve the pregnancy rate.

3. Improper use of drugs

In order to improve the pregnancy rate of female rabbits, many farmers often use various drugs such as oxytocin to promote oestrus of female rabbits. Although the rational use of this drug can effectively promote oestrus in female rabbits, we must pay attention to control the dosage. If used too much or used too many times, it will lead to the disorder of the reproductive system of female rabbits. Not only can not promote estrus, but also lead to estrus is not obvious, irregular and so on. Even if the female rabbit is found to be in estrus in time, the follicles will be affected and reduced, resulting in infertility.

4. Reproductive tract diseases

The disease resistance of female rabbits is relatively poor, and it is very easy to cause female rabbits to get sick if they are not well managed. Especially when there are some reproductive tract diseases, it will seriously affect the breeding work of female rabbits. If the female rabbit's vagina is inflamed, inflamed, or even ulcerated, it is very likely that she has suffered from reproductive tract disease. In this case, the success rate of pregnancy of female rabbits is very small. So when found, be sure to use potassium permanganate and other agents to clean and disinfect in time, and then internal sulfadiazine, at least twice a day. Mating can not be carried out until the inflammation has fully recovered.

The above is a brief introduction to the causes of female rabbit infertility. Female rabbit infertility may still be a congenital cause, which can be used to promote the excretion of follicle hormone, such as diethylstilbestrol. If you do not have estrus for a long time and the treatment effect is not good, then it should be eliminated in time. That's all for today's introduction. This article is for reference only.
