Raising the donkey industry from the past pure-duty type, to serving both meat and meat, and meat serving to produce meat-based production, is the only way for its development. At present, the time is ripe for the development of meat donkey production. In order to increase the donkey's meat production capacity and speed up the transformation of production, we must adopt comprehensive methods of breeding, crossbreeding and scientific rearing and fattening.
Establishing an excellent breeding base for donkey species
There are many excellent local donkey species in China, which are valuable gene pools for breeding improvement. In the last decade, due to the drastic decline in the number of cultured species, more effective conservation measures have been taken for these local varieties. In order to restore and establish breeding populations for donkeys in Texas (especially the “Auranoi†and Guanzhong donkeys), and strictly follow the “Variety Standardsâ€, the breeding of this species should be carried out, and the cultivation of the young pups should be strengthened to purify and rejuvenate the pups. , Selection and selection of matching, continuously improve the quality of varieties, provide donkey species for the donkey industry.
Develop hybrid improvements
Hybrids can produce "heterosis," meaning that the hybrid generation can exhibit superior growth momentum and adaptability over its predecessors. Hybridization is not only a means of meat production, but also a means of improving the donkey species. It is possible to use local female donkeys and introduce fine donkeys for crossbreeding. In order to avoid the "difficult birth" of mating pregnant female donkeys, large donkey (male) hybrid medium-sized donkey (mother) and medium-sized donkey (male) hybrid small donkey (mother) should be used. Practice has proved that the hybrid improved offspring, major new birth, rapid growth and development, body tall, meat production capacity has greatly improved.
Using scientific breeding methods
According to the actual conditions of their donkey species resources and pasture straw resources, all localities must choose a low-cost, grain-saving, and fast-paid, high-yield donkey breeding road. In the case of family rearing, it is necessary to properly develop a certain amount of professional management and raising, which is the basis for promoting the scientific raising of donkeys and raising the efficiency of raising donkeys. According to the specific circumstances can choose professional breeding, self-cultivation and self-cultivation, concentrated fattening and other methods.
Professional breeding is the purpose of breeding and selling donkeys. The basic female donkey group is selected for improved breeding. Selection and breeding are optional. Grazing is the main factor, and supplementary feeding is provided to cultivate excellent breeding back-up donkeys; self-cultivation and self-cultivation are self-cultivation. The donkey caterpillar has been consistently fattening, using the characteristics of the youngest donkey before 12 months of age to grow and grow rapidly and gaining weight quickly. It is sold directly from the fattening and selling; concentrated fattening is the purchase of shelf donkeys from areas where donkeys are widely sourced and off-site, and centralized donation Intensity of fattening, fattening period of 2 months to 3 months.
The above methods can optimize the allocation of resources, concentrate funds and technology, refine the division of production, and form an industrial chain production system, so as to achieve an overall improvement in the level of production. At the same time, it is also of great significance to improve the selection and breeding of donkey species.
