In recent years, due to the deterioration of the natural environment, coupled with the excessive hunting of wild boars by humans, excessive killing has led to a sharp decline in wild boar population. Under such circumstances, artificial breeding of wild boars not only protects the resources of wild animals, but also can better serve humanity. This is a major event that benefits the country and the people. At present, domestication of wild boars has just started in China, and Guangzhou, Shenzhen, and Hong Kong are in great demand. 1. Breeding of wild boar After purchasing wild boars, wild boars and wild boars are housed in cages for domestication. Wild boars were timid and initially afraid of people. In order to change this weakness, it is generally adopted to purchase small wild boars for domestication, and its body weight is generally 10 to 22 kg. This kind of wild boar is small in age, easy to domesticate, and highly malleable. In the domestication process, it is best to feed more than half of the wild boar and a juvenile domestic pig in a mixed ratio of 8:2. In this environment, young wild boars and domestic pigs of the same age will quickly gregarize, allowing domestic pigs to carry out activities and feeds with young boars. Wild boar is an omnivorous animal and is usually fed twice a day as a domestic pig. Because of their wild habits, they are good at picking raw food. The tender corn, red sorghum, wax gourd, potatoes, sweet potatoes, peanut pods, sweet potatoes, corn ears, pumpkins, and eggplants that are common in farms are all foods that they like to eat. When you start your family, you should feed your staple food. After one month, feed half of the raw food, feed the other half of the feed, such as cornmeal, wonton skin, bean curd residue, and powdered residue, and add the appropriate amount of salt until the wild boar basically adapts to the captive environment, and use compound feed for feeding the domestic pig. To feed boars Serve. However, some root plants should also be properly fed. 2. It is best to build wild boar sheds in high-lying areas, easy to drain, and convenient for lighting and ventilation. The original domestic pig house can also be reared with minor modifications. The new enclosure outside the nest requires cement paving. The shed asks for a nest room and an outside nest room. The Liwo Room is for wild boar sleeping and laying, about 3 meters long, about 2.8 meters wide, plus a shed to build a typical pig house style. The outer nest room for wild boar urine, diet, exercise and sun, about 3 meters long, about 2.8 meters wide, the wall with cement plaster surface, building height of 1.7 to 1.8 meters. A drinking pool can be built with masonry cement at the root of the wall for drainage. It is 1 meter long, 0.5 meter wide and 230 meters deep. It should be noted that the drinking pool should not be too deep or narrow, otherwise, when the hot weather in summer, the piglet cool in the pool, will cause pregnant sows to suffocate stillbirth phenomenon. A 1 meter wide passageway should be left between the inner and outer chambers to facilitate the free access of wild boars. The gates are generally left in front of the nest room. 3. Breeding Technique Wild boars are coarse and thin, usually gray or grayish yellow. Adult sows weigh between 90 and 130 kilograms and are sensitive to the external environment. Nipples are generally 6 to 7 pairs. Under artificial rearing conditions, the female wild boar produces 2 children each year, and each child has an average of 6 to 10 litters. Suitable breeding time is from 5 to 6 months after birth and the body weight is 40 to 60 kg. Generally, the principle of using early sows with early sows and sows with late sows is adopted. When the wild boar is estrus, the external genitalia is markedly red and swollen. When the external genitalia changes from red to dark purple, the swelling changes to slightly shriveling, or the sow's hindpaw is held by hand, and the best breeding time is when it stands still. . The mating time of male and female boars takes about 40 minutes, which is slightly longer than that of domestic pigs. Based on experience, it is advisable to adopt a compounding method, that is, to repeat the mating once every 6 to 8 hours, so that the sow fertility rate can be significantly increased. When wild boar estrus is suitable for mating, male wild boars can also be taken to the sows for 1 to 2 days. At this time, boars can be crawled and mated several times at night. After confirming the successful mating, the wild boar was expelled. After 20 days, the female wild boar was observed for estrus. Normal female wild boar estrus cycle is 18 days, if not estrus, prove that the female wild boar has been successfully mated. 4. Breeding pigs The wild boar farm must have 1 to 2 purebred wild boars. As the saying goes, the sows are good and they have a good nest. The boars are good and good. This shows the importance of breeding pigs. The selection of good wild boars is of crucial importance to the post-representation. The purebred wild boar that meets the characteristics of the wild boar, such as a body length, a leg height, and a tip of the mouth, is generally kept in mind. The offspring produced by the crossbreeding of wild boar and domestic pigs are used as species, and offspring produced by offspring have the phenomenon of returning to the ancestors. That is, the pigs produced are not like wild boars but like domestic pigs. Therefore, binary hybrids of wild boars are not suitable for seed use. In kinship, we must also prevent inbreeding in order to help our offspring become more resistant and grow quickly. 5. Development value The use of wild boar and domestic pig crossbreeding, using purebred wild boar as a male parent, and using the Duroc and Changbai as maternal females to produce hybrid special wild boars, which have the characteristics of stable genes, rapid growth and development, and they are extremely popular in the market. Good momentum for development. Experts determined that wild boar meat is fresh, nutritious, and has a high lean percentage. The carcass lean rate is 6 to 8 percentage points higher than that of domestic pigs, and the content of linoleic acid in muscles is 1.5 to 2 times higher than that of domestic pigs (linoleic acid). Currently considered to be one of the most important fatty acids to the human body). Wild boar is rich in protein and unsaturated acids and contains 17 amino acids. Wild boar ham and wild boar taste bacon processed with wild boar are well sold both at home and abroad. Each 500 grams of wild boar in Nanjing, Shanghai, and Guangzhou is priced at 15 to 30 yuan. After being domesticated, the wild boar has maintained its original appearance and characteristics of wild game, strong disease resistance, resistance to rough feeding, and strong gregariousness, and it has been favored by people. As China's accession to the WTO and the improvement of our people’s living standards, health-care meat products will surely be favored by more and more people. Based on this, wild boar aquaculture will have unlimited business opportunities.
