Abstract: After the outbreak of African swine fever (ASF), the number of breeding sows were decreased sharply. Many farms used three-breed cross (DLY) sows as breeding, and the pig production capacity was restored, but the production efficiency of DLY sows was about 20% lower than two-breed cross (LY) sows. With the normalization of AFS, farms have strengthened the construction of biosafety system, and improving the production efficiency has become the main goal of farms. The number of two-breed rotaterminal cross sows are gradually increasing, replacing DLY sows with poor production performance is becoming a trend. This paper mainly reviewed the characteristics, nutrition and management of two-breed rotaterminal cross sows, in order to provide reference for farms.

Key words: ASF, two-breed rotaterminal cross sows, nutrition, management
