Problems solved by technology
But in fact, D and G are more closely related, but they are divided into different blood lines. Therefore, the relationship between blood lines is closer than that within blood lineages, which once again shows the irrationality of the traditional blood lineage classification method.
[0003] In addition, assuming that a certain individual is relatively good, its offspring or relatives are often also relatively good. If they are divided into different bloodlines according to the traditional method, they may all be reserved for breeding, resulting in closer kinship between the boars in stock. would lose a lot of genetic diversity

Embodiment Construction
[0018] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and embodiments, but the present invention is not limited to the scope of the embodiments.
[0019] by figure 2 The boar pedigree and presence in the field is illustrated as an example. Where GG, FF, KK, LL, MM and NN are the boars present, assuming the date of birth from front to back is in the same order as above. Firstly, according to the traditional blood relationship classification method, that is, the great-grandfather is the traditional blood number of the individual, and the results in Table 1 are obtained. Then divide the new blood number: the 6 individuals in Table 1 are arranged from top to bottom according to the date of birth, so the 6 individuals have new numbers from 1 to 6 respectively. Individual 1 is the oldest boar in the field, so the traditional bloodline number B is used as its new bloodline number; the great-grandfather B of indiv...

The invention discloses a method for breeding boars and is improvement of a conventional boar blood relationship classification method. Conventional blood relationship classification regards that thegreat-grandfather of an individual is just the blood relationship number of the individual, so that three generations of grandparents and grandchildren are classified into different blood relationships, and great defects are resulted. The invention develops a novel method, not only are boars of identical great-grandfathers classified into identical blood relationships, but also boars of close genetic relationships are classified into one same blood relationship, so that accuracy of blood relationship classification of the boars is greatly improved, accurate breeding of the boars can be ensured, and loss of genetic resources can be reduced.
Description
technical field [0001] The invention relates to the field of breeding pigs, in particular to a new method for breeding boars. Background technique [0002] Consanguinity is usually defined as a group of subpopulations that share a common genetic basis, tend to be more similar in characteristics, and are more distantly related between different consanguinity than within consanguinity. However, due to the difficulty of division, people usually use the great-grandfather as the blood number of the individual. Although this method is simple to operate, it is very unreasonable. by figure 1 For example, the great-grandfathers of individuals D and F are A and B respectively. According to the traditional blood relationship, the blood relationship numbers of the two are A and B respectively. However, D and F are father-son relationships, but it is obviously unreasonable to be classified into different blood relationships. . Another example is G's great-grandfather is B, so accordi...
