What is the breeding method of wild boar? A little more detail?

In recent years, due to the deterioration of the natural environment and the indiscriminate hunting of wild boar by human beings, the number of wild boar has dropped sharply. In this case, raising wild boar artificially not only protects wildlife resources, but also serves human beings better, which is a major event that benefits the country and the people. At present, domestic wild boar domestication has just started, and there is a great demand in Guangzhou, Shenzhen and Hong Kong.

1, wild boar breeding

After buying wild boar, the male wild boar and the female wild boar are put into the fence for artificial domestication. Wild boar was timid at first. In order to change this weakness, it is generally domesticated by buying small wild boar, the weight of which is mostly 10 ~ 22 kg. Because this wild boar is young, easy to domesticate and has strong plasticity. In the process of domestication, it is best to mix more than half of wild boar with a young pig, with a ratio of 8:2. In such an environment, young wild boar and domestic pigs of the same age will soon live in groups, allowing domestic pigs to carry out activities and feed with young wild boar. Wild boar is an omnivore, generally imitating domestic pigs and feeding them twice a day. Because of its wild habits, it is good at picking raw food. Young corn, red sorghum, wax gourd, potato, sweet potato, peanut seedling, sweet potato seedling, ear of grain, pumpkin and eggplant, which are common to farmers, are all his favorite foods. At the initial stage of domestication, we should feed them with staple food. After one month, feed half of raw food and the other half of feed to domestic pigs, such as corn flour, oyster skin, bean curd residue and powder residue, and add appropriate amount of salt. After the wild boar basically adapts to the captive environment, it is fed with compound feed of domestic pigs. However, some root plants should also be properly fed.

2. Build fences and houses

It is best to choose the wild boar pen in a higher place, which is easy to drain and facilitate lighting and ventilation. The original pigsty can also be raised with a little modification. The outer nest of the new fence needs cement floor. The fence requires that the inner nest room should match the outer nest room. The nest room is about 3 meters long and 2.8 meters wide for wild boar to sleep and give birth. Build a general pigsty style with the shed. The outer nest room of wild boar for urination, eating, exercise and sunbathing is about 3 meters long and 2.8 meters wide. The wall is plastered with cement, and the building height is1.7 ~1.8m.. Cement drinking water pool can be built at the root of the wall which is convenient for drainage. It is 1 m long, 0.5 m wide and 230 cm deep. It should be noted that the drinking pool should not be too deep and too narrow, otherwise, when the weather is hot in summer, pigs will lie in the pool to enjoy the cool, which will cause pregnant sows to suffocate and die. A passage with a width of 1 m should be left between the inner nest and the outer nest to facilitate the free entry and exit of wild boar, and the gate is generally left in front of the inner nest.

3. Breeding technology

Wild boar's fur is thick and thin, generally gray or grayish yellow. Adult sows weigh 90 ~ 130 kg and are sensitive to the external environment, with 6 ~ 7 pairs of nipples. Under the condition of artificial feeding, female wild boar gives birth to 2 fetuses every year, with an average of 6 ~ 10 litter per fetus. The suitable breeding time is 5 ~ 6 months after birth and the weight is 40 ~ 60 kg. Generally, the principle of early mating of primiparous sows and late mating of multiparous sows is adopted. When wild boar is in estrus, the external genitalia is obviously red and swollen. When the external genitalia changes from red to deep purple, from swelling to miniaturization, or when the sow's hindquarters are pressed by hand, the best mating time is when it is still. It takes about 40 minutes for male and female wild boar to breed, which is slightly longer than that of domestic pigs. According to the experience, it is best to use the compound method, that is, repeat mating 1 time at intervals of 6 ~ 8 hours, which can obviously improve the conception rate of sows. When the boar is in estrus and suitable for mating, it can also be driven into the sow pen 1 ~ 2 days. At this time, male wild boar can climb and mate many times at night. After confirming the success of mating, the male boar was driven out, and after 20 days, whether the female boar was in estrus was observed. The estrus cycle of female wild boar is 18 days. If it is not estrus, it proves that the female boar has successfully mated.

4. Selection of breeding pigs

Wild boar farm must have 1 ~ 2 pure wild boars. As the saying goes, sows are good, and a litter is good; Wild boar is good, what a good slope. This shows the importance of raising pigs. Choosing a good boar is of great significance to the performance of future generations. Generally, you should pay attention to the pure wild boar, which has a long body, high legs and a sharp mouth, which conforms to the characteristics of wild boar. Using the offspring of wild boar and domestic pig as seeds, the bred offspring have atavism, that is, some pigs look like domestic pigs rather than wild boars. Therefore, the special wild boar of binary hybridization should not be kept as seeds. It is also necessary to prevent consanguineous inbreeding, which will help their offspring to have strong disease resistance and grow rapidly.

5, the development value utilization

A special wild boar produced by crossing wild boar with domestic pig, with pure wild boar as the male parent and Duroc and Changbai as the female parent, has the characteristics of stable genes and rapid growth and development, and has shown excellent development momentum in the market. According to experts' determination, wild boar has tender meat, rich nutrition and high lean meat rate. The lean meat percentage of its carcass is 6-8 percentage points higher than that of domestic pigs, and the content of linoleic acid in its muscle is 1.5-2 times higher than that of domestic pigs (linoleic acid is considered to be the most important fatty acid in human body at present). Wild boar is rich in protein and unsaturated acids, and contains 17 amino acids. Wild boar ham sausage and wild boar bacon processed by wild boar sell well in domestic and foreign markets. In Nanjing, Shanghai, Guangzhou and other markets, the price of boars per 500g is 15 ~ 30 yuan. After domestication, wild boar has maintained its original appearance and shape, and has the characteristics of game, strong disease resistance, rough feeding resistance and strong gregarious, so it is favored by people. With China's entry into WTO and the improvement of people's living standards, health meat food will be favored by more and more people. Based on this, wild boar breeding will have unlimited business opportunities.
