The invention relates to the technical field of raise
livestock breeding and cultivating, and in particular relates to a method for cross-breeding a special
wild boar through a domestic
boar and a
wild boar. The method comprises the steps of patriarchal breeding, maternal breeding, patriarchal and maternal cross-breeding, and continuous progeny selection, wherein patriarchal breeding and maternal breeding involve first cross and first backcross; patriarchal secondary
boar contains 75% of
consanguinity of
wild boar, and 25% of
consanguinity of duroc and has the characteristics of being fast to grow and high in
lean meat percentage; maternal secondary
boar contains 75% of
consanguinity of wild boar, and 25% of consanguinity of Jiangkou radish boar and has the characteristics of growing well on the roughest of
forage, and being peaceful, and high in maternity; patriarchal secondary boar and maternal secondary boar which are gained after
backcrossing are crossed to obtain first-generation special boar, and then the three-generation selection is performed for the first-generation special bar to obtain a special boar core group that contains 75% of consanguinity of wild boar, 1.25% of consanguinity of duroc, and 12.5% of consanguinity of Jiangkou radish boar. According to the method, the size and appearance of the special wild boar are close to that of the wild boar, and the special wild bar is peaceful and grows well on the roughest of
forage; white doar and flower boar descendants nearly do not appear; the special wild boar grows fast, the meat is delicious, and the
lean meat percentage reaches 66%;
linoleic acid in meat accounts for 8% to the maximum based on the total
fatty acid, which is 2 to 3 times that of the common domestic boar, and thus the benefit is brought to
human health.
