Adaptative changes of insulin, glucagons, and mRNA level of PEPCK-C occurred in ketotic dairy cows, which were in favor of increased gluconeogenesis and restoration of NEB.
A low ratio between insulin and glucagons due to hypoinsulinemia which occured in ketotic dairy cows (Table 2), and which often appears during negative energy balance in early lactation, would stimulate fat mobilization (Herdth, 2000) leading to a great amount of NEFA being mobilized from fat tissue and, exceeding the oxidative capacity of the liver, increased ketone body formation, and occurrence of ketosis (Hayirli, 2002).
