[Effects of a surgical reposition of left-sided abomasal displacement on parameters of energy metabolism in dairy cows].

The objective of this study was to investigate whether the surgical replacement of left abomasal displacement (omentopexy) leads to typical stress changes in the energetic metabolism of dairy cows: twenty dairy cows, aged approximately 4.4 years were used. Six blood samples were collected in order to determine concentrations of cortisol, glucose, free fatty acids, L(+)-lactate, and beta-hydroxybutyrate once before, and five times after surgery. The surgical intervention led to a significant elevation in cortisol, glucose, FFA and lactate blood levels. These stress-related changes were observed over a 24 hour-period after surgery. In contrast to these parameters, serum concentration of beta-hydroxybutyrate slowly decreased over the entire observation period (72 hours). The results show that surgical correction of left abomasal displacement has a short-term stress effect on energy metabolism of dairy cows.
