Problems solved by technology

[0010] 3. There are not many breeding and domestication of purebred wild boars
[0012] 1. The current method of domestication and reproduction of wild boars may be a variation in the characteristics of wild boars, which may cause this species to lose the characteristics of the original species
[0013] 2. Some areas adopt free-range breeding and hybridization with domestic pigs. This method lacks norms and science, and the breeds cultivated are not stable enough and relatively blind
[0014] 3. The current method of domestication and breeding of wild boars is not the domestication and breeding of purebred wild boars, but the hybridization and improvement of domestic pigs and wild boars

Embodiment 1

[0050] Example 1: Binary crossbreeding method of wild boar: select the male parent (A) of the Longdong wild boar variety and the female parent (B) of the Changbai wild boar variety to hybridize to generate the first generation of hybrid F1: A variety contains ♂ (male) × B variety ♀ (female), F1 hybrid wild boar (50% A, 50% B), the lineage of hybrid F1 is 50% of the male parent and 50% of the female parent, and the heterosis rate of this hybrid can reach up to about 20%. The ratio of the dominant offspring can reach 100%, its heredity is relatively stable, the hybridization effect is reliable, and all of them can be used as commercial meat wild boars. Using foreign breeds as male parents not only increases the cost of commercial pigs, but is also not as simple and easy as binary hybridization. Therefore, each pig farm should choose the hybridization method according to the specific situation.

[0051] Embodiment 2, the binary backcross breeding method of wild boar: select the male parent (A) of Longdong wild boar variety and the female parent (B) of Changbai wild boar variety to carry out crossbreeding and produce F1 of hybrid generation, select excellent hybrid first generation F1 sow, and The boars of the original parent breed are backcrossed to produce the first generation of backcross, and then the first generation of backcross will continue to be backcrossed with the boars of the original parent breed to produce the second generation of backcross. After three generations of reincarnation, the bloodlines of the two breeds contained in the offspring basically tend to be balanced, each accounting for 1 / 3 or 2 / 3 and interchanging from generation to generation: A♂×B♀, B♂×Za 1♀ (A 50%, B 50%), A ♂ × Miscellaneous 2♀ (A 25%, B 75%), B ♂ ​​× Miscellaneous 3♀ (A 62.5%, B 37.5%), Miscellaneous 4 (A 31.25%, 68.75%). The reincarnation hybridization of the two breeds only ne...

Abstract

A hybridization method for naturalizing and reproducing pure-breed wild boar features that the diphyletic hybridization, diphyletic backcross, and triphyletic hybridization are used to increase bearing rate, ablactative survival rate and the weight of ablactative individuals.

Description

technical field [0001] The invention belongs to the field of animal husbandry and relates to the breeding of a wild animal, in particular to a breeding method of a purebred wild boar. technical background [0002] As a new breed in the pig family, wild boar has strong aroma, high lean meat rate, and rich nutrition (contains 17 kinds of amino acids, and the most important and necessary fatty acid linoleic acid in the human body is 2.5 times that of domestic pigs.), fat content Low in fat (the fat of the ham is only 50% of that of domestic pigs), it has characteristics and value that domestic pigs cannot match. [0003] Biological characteristics of wild boar: [0004] (1) Wildness, feeding habits and moulting. Wild boars are wild, aggressive and easily frightened, sensitive to nerves, and aggressive when angry. Breeders should pay attention to safety; wild boars have a mixed diet, mainly including branches and leaves, weeds, green feed, and grains There are two ways to mol...
