Description
Technical Field
The invention belongs to the technical field of animal breeding, and particularly relates to a hybrid breeding method of Yulong black pigs.
Background
With the economic development and the improvement of living standard, the demand of people for food is only enough in quantity, and more people begin to pay attention to the quality and safety of food. The ecological identification food without pollution and safety is produced at the same time. In China, the ecological identification food mainly comprises three types of organic food, green food and pollution-free food, the scale of development of the ecological identification food in China is still very limited, the ecological identification food entering the market cannot be accepted by most consumers, and the market share is very low. Secondly, the original environment of the rural area is changed due to the fact that the urbanization process is accelerated. The breeding industry is initially large-scale, the combination of concentrated breeding and scattered breeding is adopted, the cooperation mode of companies and farmers is more, and the quantity of large-scale breeding is relatively small. The existing live pigs mostly adopt a centralized captive breeding mode, the meat quality and the nutrition value are not high, and the disease resistance of individuals is not high.
In a high-altitude area at Lijiang province, the mountain bodies are numerous, and the original country atmosphere is kept in many places, while the breeding base selected by the rural village of the Yao garden is located in the deep mountain abdominal land and far away from the urban area in the Yongsheng county Sabaxiang and the Yulong county Taian county, and the natural growth conditions of Yulong Xiaohei and the Naxi Tuxiang pig are met no matter the altitude, soil or water quality and vegetation. The cultivation mode is mainly ecological cultivation, and by applying the ecological principle, the biological diversity and stability are protected, and various resources are reasonably utilized, so that the optimal ecological benefit and economic benefit are obtained. Ecological breeding is a production mode advocated in rural areas in China. Compared with intensive and industrial culture modes, the ecological culture method is characterized in that livestock and poultry naturally grow in natural ecological environment according to the original growth and development rule of the livestock and poultry, and the growth environment is not artificially manufactured and the livestock and poultry rapidly grow by using a growth promoter in violation of the original growth and development rule of the livestock and poultry.

s3: cultivating a quaternary female parent, driving the two-dimensional female parent and the two-dimensional male parent in the oestrous period into the same pigsty and isolating the two-dimensional female parent and the two-dimensional male parent from each other through a fence, hybridizing the two-dimensional female parent and the two-dimensional male parent one by one after the two-dimensional female parent is familiar with the surrounding environment, and collecting the sow piglets as the quaternary female parent for feeding after the two-dimensional female parent farrowing;
s4: breeding five-element piglets, selecting the Bakha pig in an estrus as a male parent, driving a quaternary female parent in the estrus into a pigsty of the Bakha pig, mutually isolating the Bakha pig male parent and the quaternary female parent by using a fence, and driving the quaternary female parent into a colony house of the Bakha pig male parent for hybridization after the Bakha pig male parent and the quaternary female parent are familiar with the surrounding environment;
s5: feeding five-element piglets, and breeding after the four-element female parent farrowing to obtain five-element Yulong small black piglets as commercial pigs.
Preferably, the yulong black pig in step S1 is a black pig in the high-altitude area of lijiang.
Preferably, after the first hybridization of the male parent and the female parent is performed in steps S1, S4 and S5, the mating is repeated once more at an interval of 6-8 hours to improve the conception rate of the female parent.
