For large-scale farming farmers, the selection of species must not be too random, at the same time, the selection of excellent young rabbits as backup rabbit breeding can effectively improve the reproductive rate. Here's a look at the key points of selecting and retaining rabbits.
Female rabbit in the first embryo production of the rabbit generally should not be left as a kind of rabbit, because most female rabbit in the first embryo when the body development is not fully mature, the reproduction of the rabbit is small, slow growth and other problems, it is best to choose the second embryo after the rabbit as a kind of rabbit.
In the case of low reproductive rate of female rabbits, their offspring should not be kept as rabbits. If the female rabbits produce only 5 rabbits in each successive embryo, and the estrus is slow and estrus is not obvious, the reproductive rate is low. The selected rabbits should choose female rabbits to give birth to more than 6-7 rabbits.
Breeding rabbits also need to be checked for genetic diseases, such as abnormal tooth growth, figure-leg and deformity, as rabbits suffering from such diseases are often difficult to feed and will have a certain impact on reproduction, so it is not advisable to keep them as breeding rabbits.
In the case of poor maternal rabbit, its offspring should not be left as a kind of rabbit. In addition to human factors, most of the offspring bred by the mother rabbit with large correlation of poor maternal sex are more poor, prone to postpartum not tearing hair, no milk, bite and other problems.
To be a little bigger rabbit will be selected again, male rabbit generally 4 months of age will “drop eggs”, for no “drop eggs” male rabbit to be eliminated, female rabbit is to see the number of nipples, generally the number of female rabbit nipples is 6~8.
Mengyin long-haired rabbit mother rabbit a fetus may appear to give birth to less, do not tear hair, not breastfeeding, bite the phenomenon of young rabbit, and the second, the third is still so the case needs to be eliminated.
General small and medium-sized rabbit 5~6 months of age for the initial match, large rabbit 7 months of age above the initial match, for the weight of rabbits should be eliminated according to the situation. In addition, male rabbits trained not to climb, female rabbits repeatedly induced estrus is still not estrus or refuse to accept mating should be eliminated.
The above is the selection of rabbits in the process of reserving some points of rabbit introduction, I hope to help you. For more information, please visit www.myxinhua.com!
