NEFA) and blood (BHB) in early lactation cows. Glucose levels rise during childbirth. Caused by hormonal changes in the body to support the creation of milk by a process of glucose and the breakdown of glycogen in the body) level BHBA increases in the postpartum period due to the breakdown of energy from fat tissue volume to meet the yield. plenty of milk The concentration of the enzyme protein made by the liver (SGOT) increases in labor. And a decline in the birth before a gradual increase in the 42 postpartum (P = 0.0066) levels SGOT increased during childbirth due to a breakdown of the fatty tissue to meet a lot of energy in. Creating milk And the increase of liver function in the process of synthesis of glucose in the postpartum period
