| Summary / Zusammenfassung | Approximately 3% of all bovine fetuses die during or shortly after birth. In the majority of cases the reason for this peripartal mortality is dystocia, which causes a protraction in the birth progress. This bears the risk of fetal damage caused by hypoxia, hypercapnia and acidosis. In the field methods for monitoring the well-being of the bovine fetus during parturition are almost lacking. The evaluation of vitality is based mainly on reflexes, meconium staining of the fetus and the amniotic fluid or the detection of a heart beat in the fetus, but they do not allow an accurate estimate of fetal acidosis. The aim of the projekt is to develop new methods which may help to recognize fetal distress. | ||||||||
