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 breeding method for breeding pigs, which is an improvement on the traditional method for dividing bloodlines of boars. The traditional blood relationship classification considers that the great-grandfather of an individual is his or her blood relationship number, which leads to the three generations of grandparents and grandchildren being divided into different blood relationships, which has great disadvantages. The present invention develops a new method, which can not only classify boars with the same great-grandfather into the same blood lineage, but also classify boars with close kinship into the same blood lineage, which greatly improves the accuracy of boar blood lineage classification, thereby ensuring The selection of breeding pigs is more accurate and the loss of genetic resources is 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...
