Harbin White Pig

Harbin White Pig

　　Abbreviated as Harbin White Pig, it is mainly distributed in the southern and central regions of Heilongjiang Province. It was developed through progressive crossbreeding of the original Harbin White Pig with the Soviet White Pig, followed by intercrossing in the second generation to fix the traits. There are currently around 100,000 breeding sows, distributed along railway lines such as the Binzhou, Binsui, and Mudanjiang-Jiamusi routes. The Harbin White Pig has strong cold resistance and good feed utilization capabilities.
