② A wild Du (F2) boar crossed with a wild sow with 37.5% wild boar pedigree to produce a fattening boar with 56% wild boar pedigree.

③ Wild Du (F2) wild boar× Wild Guan (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

④ Wild Du (F3) boar× Wild Guan (F 1) sow crossed to produce fattened wild boar with 68.75% wild boar blood.

The special wild boar bred by crossing Guanling pig and wild boar has strong adaptability and delicious meat. It is suitable to slaughter with a weight of 75 ~ 85 kg, and the slaughter rate is high. Fat wild boar with 56% ~ 62.5% wild boar blood is the best. The special wild boar bred by crossing Guanling pig and wild boar is characterized by good tenderness, and the special wild boar with 62.5% wild boar blood is the best, which is suitable for hot pot rinsing and has a good market. (2) Wujin pig ① wild boar Du (F2) boar× wild black sow with 37.5% wild boar pedigree produces fattening wild boar with 56% wild boar pedigree.

② Wild Du (F2) wild boar× Wild Wu (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

③ Wild Du (F3) boar× Wild Wu (F 1) sow crossed to produce fattened wild boar with 68.75% wild boar blood.

The special wild boar bred by crossing Wujin pig and wild boar has fresh meat and rich flavor. Suitable for producing suckling pigs and fattening wild boars, and suitable for slaughtering with a weight of 70-80 kg. The fattened boar with 62.5% wild boar blood has the best meat quality, and the suckling pig with 56% wild boar blood has the best meat quality. Among Wujin pigs, Huomao pig is a hybrid with wild boar, which looks cool, like a pure wild boar. Special wild boar containing 50% wild boar blood is very similar to pure wild boar, which is very beneficial to the breeding pig sales of breeding pig sellers. In order to ensure the quality of special wild boar, although hybrid wild boar has advantages in appearance, it must also ensure the quality. The pedigree of special wild boar shall not be less than 37.5% for females and 68.75% for males. The production performance of the special wild boar bred by crossing between Wuji pig and wild boar is the same as that of Huomao pig in all aspects, but its coat color is not as cool as that of the hybrid offspring of Huomao pig and wild boar, like pure wild boar. (3) Southern Yunnan Small-Ear Pig ① crossbred with improved boar× Southern Yunnan Small-Ear Pig sow to produce fattening boar with 50% wild boar blood.

② Wild Du (F2) boars crossed with Yunnan wild boar and sow with 37.5% wild boar pedigree to produce fattening wild boar with 56% wild boar pedigree.

③ Wild Du (F2) wild boar× wild Dian (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

④ Wild Du (F3) boar× wild Dian (F 1) sow crossed to produce fattened wild boar with 68.75% wild boar blood.

The special wild boar bred by crossing small-ear pig and southern Yunnan wild boar has tender meat and high meat yield, which is suitable for both suckling pig and fattening wild boar. The fattened boar with 62.5% ~ 68.75% wild boar blood has the best meat quality, and the suckling pig with 56% wild boar blood has the best meat quality. The hybrid combination of wild boar and southern Yunnan small-ear pig is the best among the known Xiang pigs, and its production performance and meat quality have achieved satisfactory results. This provides a useful attempt for the protection and development of small-ear pigs in southern Yunnan. It is hoped that breeders who want to cross-breed special wild boar with small-ear pigs in southern Yunnan will not introduce too many foreign pig lineages in pursuit of growth speed and meat yield, which will affect pork quality. In principle, the origin of foreign pigs should not exceed 25%. (4) Baoshan Pig ① Wild Du (F2) boar× wild boar with 37.5% wild boar blood to produce fattening wild boar with 56% wild boar blood.

② Wild Du (F2) wild boar× wild abalone (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

The special wild boar bred by hybridization between Baoshan pig and wild boar is large in size, high in meat yield and good in meat quality. But the growth rate is slow, which is not suitable for large-scale culture. The special wild boar bred by wild boar hybrid has strong resistance to rough feeding, and still has good growth characteristics at low nutritional level, which is suitable for rural fencing and grazing. The fattened wild boar with 62.5% wild boar blood has the best meat quality.

It is worth noting that the litter rate of special wild boar bred by crossing Baoshan pig with wild boar has also been significantly improved, with 7-8 primiparous sows and 0.8 multiparous sows/kloc-0. We should make full use of this hybrid advantage, carry out hybridization between fine-boned pigs and wild boars, and cultivate new varieties of wild excellent special wild boars. In Baoshan pigs, it is necessary to make good use of the hybrid appearance of Huomaoqun pigs and wild boar and the cool image of pure wild boar to produce breeding pigs and expand breeding benefits. (5) Dahewu Pig ① Wild Du (F2) boar× Wild Da (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

② Wild Du (F3) boar× Wild Da (F 1) sow crossed to produce fattened wild boar with 68.75% wild boar blood.

The special wild boar bred by crossing Dahewu pig and wild boar has fast production speed and high meat yield, which is suitable for large-scale breeding. (6) Neijiang Pig ① Wild Du (F2) boar× wild sow with 37.5% wild boar blood to produce fattening wild boar with 56% wild boar blood.

② Wild Du (F2) wild boar× wild nei (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

③ Wild Du (F3) wild boar× wild nei (F 1) sow crossed to produce fattened wild boar with 68.75% wild boar blood.

The special wild boar bred by crossing Neijiang pig and wild boar has strong adaptability, high meat yield, many litters and delicious meat. The suitable slaughter weight is 75 ~ 85 kg, and the fattened wild boar with 68.8% wild boar blood is the best. (7) Yan 'an Pig ① Wild Boar Du (F2) Boar× Wild Boar Ya sow 37.5% wild boar pedigree to produce fattening wild boar 56% wild boar pedigree.

② Wild Du (F2) wild boar× wild Ya (F 1) sow crossed to produce fattened wild boar with 62.5% wild boar blood.

③ Wild Du (F3) boar× Wild Ya (F 1) sow crossed to produce fattened boar with 68.75% wild boar blood.

The production performance and characteristics of special wild boar bred by crossing Yanan pig and wild boar are similar to Neijiang pig. Please refer to Neijiang pig section. (8) Tibetan pig ① A wild Du (F2) boar× a Tibetan sow was crossed to produce a suckling pig containing 35% wild boar blood.

② Wild Du (F 1) wild boar× Tibetan sow crossed to produce fattened boar with 25% wild boar blood.

The special wild boar bred by crossing Tibetan pig and wild boar adapts to the living environment in alpine region and is also suitable for grazing. Suitable for producing suckling pigs, not for fattening wild boars. The suckling pig with 25% wild boar blood is the best, and the fattening wild boar with 35% wild boar blood is the best.

Tibetan pigs are small in size and slow in growth, and the growth rate is even slower after crossing with wild boar. The special wild boar bred by crossbreeding wild boar and Tibetan pig weighs only 40 kg at the age of 12 months, and its captive weight slightly increases to 55 kg. The meat yield is not high, only about 55%.

In practice, Tibetan pigs are not suitable for crossbreeding with wild boar to cultivate special wild boar, and their meat quality and other production traits have not been greatly improved, which is of little significance in terms of economic benefits. If you want to try, you can only produce suckling pigs. There is still a certain production benefit in producing about 5 kilograms of suckling pigs.
