Abstract: Sow reproductive disorder is one of the important factors that restrict the development of Chinese pig industry. It can cause abnormal estrus, repeated infertility, abortion stillbirth, mummified fetus and weak fetus, which leads to the prolongation of sow breeding cycle, the decrease of live (healthy) litter size and the shortening of service life, and seriously affects the economic benefits. Sow reproductive disorder syndrome (SRDS) is affected by many factors such as genetics, functional disorders, environment, nutrition and disease. This paper has reviewed recent studies on the causes, pathogenesis and prevention measures of SRDS. In order to provide new ideas and reference for prevention and control of sow reproductive disorder.

Key words: sow, reproductive disorders, pathogenesis, control measures
