In other words, the sows required for the renewal of the sows in the paternal farm 30 are all produced purely in the paternal farm 30, and all the pigs are only born but not entered. Similarly, the phenotype and genotype of the pigs raised in the paternal farm 30 can be determined on a large scale, high-intensity genome selection can be performed, and high-quality purebred boars and sows can be bred. The selected sows may be used for sow renewal in the paternal farm 30 and the selected boars may enter the boar station 40. And selling unselected boars and sows completely.
In this embodiment, the male stock station 40 is used to raise male stocks and provide selective semen based on the raised male stocks. In particular, the sire station 40 is used to produce commercial swine essence. The male stock station 40 breeds the pure male pigs bred from the male parent farm 30, produces commercial semen, and provides the commercial semen to the female parent farm 20 and the female parent farm 30.
Thus, the combination breeding can be realized by the sire station 40, the female parent farm 20 and the male parent farm 30. Further, when the number of the maternal plants 20 is plural, the co-breeding of the maternal plant 20 and the paternal plant 30 refers to the co-breeding of the paternal plant 30 and all the maternal plants 20.
Thus, disease transmission can be minimized by self-circulation production by sows in the maternal and paternal farms 20, 30. Through the stock station 40, realize the joint breeding in female parent field 20 and male parent field 30, can improve the breeding pig speed, promote breeding pig quality.
