Weiyang Pig, a high-end pork brand launched by Ding Lei, mainly uses whole grains and black pigs that are slowly raised for one year. Because it is more nutritious than the commonly eaten white pig, it has been highly praised by the health care and food circles. When raising weiyang pigs, breeding should be carried out according to the breeding period. The breeding cycle of Weiyang pigs is 6 months. After more than 6 months, the breeding effect will be different. The reproductive cycle is a complete reproductive process.
