Wild boar (scientific name Sus scrofa), also known as mountain pig, is an animal of the genus Pig. Wild boar can be divided into European wild boar and Asian wild boar. There are 27 subspecies in the world, and there are some differences between subspecies. The chromosome number (2n) is between 36 and 38, such as 2n=36 or 37 in western European wild boar and 2n=38 in Japanese wild boar, but there is no reproductive obstacle between them.
They can have offspring and are widely distributed in the world. However, due to the sharp reduction of human hunting and living environment, the number has decreased sharply, and it has been listed as an endangered species by many countries. Wild boar is an omnivore and eats whatever it can. There are generally 2-3 sows and a group of piglets in the wild boar herd, and boars only join the herd in estrus.
Nowadays, as one of the main sources of human meat food, domestic pigs were domesticated by wild boars 8,000 years ago. Wild boar is not only very different from domestic pig in appearance, but also much slower and heavier than domestic pig.

Wild boar breeding technology
First, feeding
Generally, small wild boar is purchased and domesticated when working, and its weight is 10 ~ 22kg. In the process of domestication, it is best to adopt the polyculture mode of domestic pigs accounting for 20% and wild boar accounting for 80%. Usually feed it twice a day like a domestic pig. In the initial stage of domestic feeding, raw food should be used for feeding. After a month, half of them were fed raw food, and the other half were fed domestic pig feed.
Such as corn flour, bran, bean curd residue and powder residue; Add the right amount of salt, mix and feed. After the wild boar is basically adapted to captivity, it can be fed with domestic pig feed, but some rhizomes and foliage plants should also be properly fed.
Second, disease prevention.
Wild boar has the characteristics of clean nature, strong disease resistance and not easy to get sick. Wild boar pens should be disinfected regularly and kept clean. Usually disinfected once every half month. Disinfection can be carried out with 10% ~ 20% lime water, 10% potassium permanganate solution and 5% ~ 10% bleaching powder.
Clean the pigsty at least once a day. Feed water in time, and do a good job of heat preservation and heatstroke prevention in winter and summer.
Piglets should be injected with piglet edema disease vaccine within 15 days old, piglet paratyphoid vaccine at 20 days old, and triple vaccine of swine fever, swine erysipelas and swine pneumonia at 30 days old. The dosage of each vaccine should be used according to the instructions. Wild boar is injected with the triple vaccine of swine fever, erysipelas and pneumonia once every six months, 2ml/ head.
