Breeding technique of meat donkey

Raising donkeys is now a popular special breeding project in China. The nutritional value of donkey meat is very high, and donkey skin is one of the main raw materials of donkey gelatin, and all parts of the body, such as hair, bones, fat and so on, have a wide range of uses. So when we raise meat donkeys, how do we breed? The following editor brings you the breeding technology of the meat donkey, let's have a look!

1. Estrus identification

The estrus period of the meat donkey is relatively long, so when we breed, in order to ensure the appropriate breeding time and minimize the breeding times of the meat donkey, we can improve the conception rate. We must do a good job in identifying the estrus of the meat donkey, such as an ovulation test for the female donkey. First of all, you can carry out external observation, testing and other work, and then check the vagina, rectum and other work, generally focusing on the rectum.

2. Estrus season

The estrus season of the meat donkey is variable, and it is a kind of animal with multi-season oestrus. Estrus usually reaches its peak season from March to June every year, but the estrus phenomenon weakens slightly during this period because the temperature is very high from July to August, which can cause hardness to the growth of donkeys. After the donkey is in estrus, it usually extends to the late autumn of each year before gradually weakening. In the estrus season, it is the best time to breed the donkey. If the climate is right and the feeding and management methods are proper, then the female donkey can be in estrus for many years.

3. Mating process

When the meat donkey is mating naturally, the male donkey will slowly approach the female donkey, showing a series of phenomena such as sexual impulse, courtship, genital erection, climbing across the female donkey and so on. After climbing, mating begins, usually for about a minute. After the female donkey is in estrus, the cervix is fully opened, and then the male donkey breeds the fertilization rate through natural mating. However, artificial insemination can also be carried out, but there are certain technical requirements. Because the estrus time of the female donkey is relatively long, so the mating time can not be well controlled, but the fertilization ability of the sperm of the male donkey can reach about 4 days. Therefore, mating every other day has little effect on the conception rate of female donkeys.

4. Pregnancy examination

About 20 days after insemination, donkeys should have their first pregnancy test to avoid empty pregnancy caused by recessive estrus. Or miscarriage caused by wig estrus. In pregnancy examination, there are generally methods such as observing the outside and examining the vagina and rectum. For example, the observation of the vagina is mainly to check the mucous membrane, cervix and so on, while the rectum is also to check the ovaries and other conditions to determine whether it is pregnant or not. The main thing is to do different operations according to the method used.

The above is a brief introduction to the breeding technology of meat donkeys. As a matter of fact, the reproduction of meat donkeys is similar to that of domestic animals, and it is mainly necessary to do a good job in estrus identification and breeding. That's all for today's introduction. This article is for reference only. I hope it can help you all.
