Breeding technique of Rex Rabbit

Rex rabbit is a very important kind of fur rabbit in China, and its breeding area is second only to meat rabbit in our country. The economic value of Rex rabbit is also very high, so there are more and more breeders. When breeding Rex rabbits, mating is very important, which directly affects the yield of Rex rabbits. So how to breed the Rex rabbit exactly? The following editor brings you the breeding technology of Rex rabbit, let's have a look!

1. Identify estrus

When breeding Rex rabbits, it is necessary to find the oestrus of Rex rabbits in time, which is convenient to arrange the mating time and can effectively improve the mating conception rate. When in estrus, the Rex rabbit's food intake will decrease, its vitality will increase, and it will run around. When entering the peak estrus, the rabbit will climb across the same cage, and if there is a male rabbit nearby, he will flirt with the male rabbit. And will raise the tail and accept the mating behavior of the male rabbit. At this time, when you look at the female rabbit's vulva, you will find that it is red and swollen, moist and so on. The initial color is pink, and the later stage is black and purple.

2. Natural mating

Natural mating is to mix male and female rabbits together and let them mate naturally. Natural mating can make Rex rabbits breed in time and avoid missing mating. But there are also many disadvantages, that is, they are unable to choose their own mating, which is prone to inbreeding, resulting in the degradation of varieties and the reduction of hair quality. And if mixed together, the male rabbit will continue to catch up with the female rabbit, resulting in excessive physical exertion, reducing the semen quality of the male rabbit, resulting in insufficient litter. Finally, it will also cause fights between male rabbits, which will not only reduce the quality of breeding, but also easily lead to various diseases.

3. Artificial mating

Artificial mating is to raise separately raised estrus female rabbits and male rabbits to promote mating, and then put the female rabbits into the original cage after successful mating. This method is divided into mono-mating and group mating, in which a female rabbit is put into a cage to mate with a male rabbit, and then put into other female rabbits in about two hours. Group mating is to put 6-7 estrus female rabbits at once, let them mate freely, and then separate them after about a day or so. In this way, we can select and mate, avoid inbreeding, improve the overall quality of Rex rabbits, and reasonably arrange the breeding of male rabbits and improve the physique of breeding rabbits. But it is time-consuming and laborious, and it is mainly used in all kinds of large-scale breeding farms.

4. Artificial insemination

Artificial insemination is a newly developed technique for breeding Rex rabbits in recent years, which can maximize the value of breeding male rabbits. Improving the utilization rate of semen and pregnancy rate can quickly enhance the overall quality of rabbits and reduce the incidence of disease. Moreover, the breeding ability of male rabbits is enhanced, the amount of feed can be reduced and the breeding cost can be reduced. However, artificial insemination in semen collection and insemination need to be carried out manually, there is a more complex process, there are certain technical requirements. It is difficult to complete under general conditions, and it is only suitable for modern farms with strong technology and complete facilities.

The above is a brief introduction to the breeding technology of Rex rabbit. We have to choose reasonable breeding methods according to our own culture technology and scale, for example, farmers with small scale and simple management usually give priority to natural mating. That's all for today's introduction. This article is for reference only. I hope it can help you all.
