Scope
Main technical content: It often occurs in high-yielding cows. After calving, the milk production increases, but the intake of dry matter is insufficient, resulting in an energy negative balance in the body and low blood sugar levels. The cows use a large amount of body fat to convert it into ketone bodies, which in turn affects the liver's metabolism of blood sugar and leads to the accumulation of ketone bodies in the body.
