[Objective]To investigate the incidence and control status of ketosis in dairy cow on large-scale pastures in China in 2021. [Method]A total of 105 large-scale farms were selected to investigate the basic situation of ketosis,including the incidence,diagnosis and monitoring methods,treatment methods,cure rate,prevention and control methods,and treatment costs. [Result]The results showed that the average yield of dairy cow was 9.7 t per unit area,and the average incidence of ketosis was 17.9%,which was higher than the control target required by foreign countries. The detection of blood β-hydroxybutyric acid concentration is the main method for the diagnosis and monitoring of ketosis in dairy cows in most pastures. The cure rate of ketosis in dairy cows is more than 90% regardless of single or comprehensive measures,and the effect of comprehensive prevention and control of ketosis in dairy cows is significantly better than that of single measure. At the same time,the corresponding summary and suggestions are given. However,more research is needed on the incidence control target,diagnosis and monitoring,treatment,prevention and control of ketosis in dairy cow on large-scale pastures in China,and the corresponding technical specifications need to be improved and formulated to provide technical support for the efficient prevention and control of ketosis in dairy cow on large-scale pastures.
