Causes and prevention methods of fetal transformation in long-haired rabbits

Long-haired rabbit is an important economic rabbit breed, and its hair is mainly used for weaving. nowadays, there is a huge demand for it all over the world, and its breeding prospect and economic value are very high. However, in the process of breeding, there will be a phenomenon of fetal transformation, which affects the development of long-haired rabbits. It means that the embryo dies early in the uterus of long-haired rabbits and then is absorbed by the uterine mucosa without any symptoms of abortion. So what is the reason for the transformation of long-haired rabbits? How to prevent and cure it? Let's take a look.

First, reasons

1. The temperature is too high

In the early stage of pregnancy, the temperature and humidity of the breeding environment are higher, especially when the temperature exceeds the bearing point, the resistance of pregnant rabbits will decrease, resulting in the phenomenon of fetal transformation.

2. The female rabbit has a weak physique.

During pregnancy, the female rabbit is emaciated, the physique is weak, and the nutrition is insufficient. During the embryonic development, it should lead to fetal transformation due to the lack of adequate nutrition.

3. Fertilized eggs are weak.

Weak insemination will cause the embryo to stop developing when it grows to a certain extent, resulting in metamorphosis, which generally occurs when the breeding rabbit is aging, the productivity is insufficient, or when the breeding rabbit has not yet reached the time of mating, forced breeding will also occur.

4. Disease

During the pregnancy of the female rabbit, if inflammatory diseases occur in the uterus and vagina, it will endanger the growth of the embryo and lead to fetal transformation.

5. The feed is not fresh

When pregnant, the female rabbit should be fed enough feed to ensure its nutritional needs, but if the feed is deteriorated and moldy, the female rabbit will lead to diarrhea and other symptoms after eating, resulting in physical weakness and fetal transformation.

6. Vitamin deficiency

Do not pay attention to uniform nutrition when feeding, do not feed green fodder for a long time, or do not pay attention to the role of vitamins when feeding, resulting in long-term lack of vitamins and transformation of the fetus.

II. Prevention and control methods

According to the above reasons leading to the transformation of the fetus, the right medicine for prevention and treatment, the temperature caused by high temperature, the mother rabbit pregnancy should be strictly controlled temperature, long-haired rabbits can survive in the temperature between 5-30 degrees, the highest temperature can not exceed 35 degrees, otherwise it will cause metamorphosis, it is recommended to control the temperature at 15-28 degrees. During pregnancy, it is necessary to strengthen nutritional supply and increase the proportion of concentrate, so that female rabbits have enough nutrition to promote embryo growth, but keep in mind that the feed must be fresh, and pay attention to balanced nutrition, especially vitamins. When mating, we should pay attention to the age of breeding rabbits, the over-old breeding rabbits should be eliminated in time, and the young breeding rabbits must reach the breeding age before breeding. It is necessary to strengthen the prevention and control of diseases, keep the breeding environment clean and clean, disinfect regularly, restrain the growth of bacteria, and reduce the incidence of diseases.

The above are the reasons and prevention and treatment of long-haired rabbits, hope to help you, want to know more about the breeding knowledge of long-haired rabbits, please pay attention to us.
