Fetal sheep research involves studying the development and physiology of sheep fetuses during pregnancy. This research area is often used to investigate fetal growth, organ development, and responses to various stimuli or interventions. Fetal sheep are commonly used as a model for studying human fetal development due to similarities in anatomy, physiology, and gestational processes. Researchers may use techniques such as ultrasound imaging, blood sampling, and surgical procedures to study fetal sheep development and responses. Fetal sheep research can provide valuable insights into prenatal conditions, developmental disorders, and the effects of maternal nutrition or exposure to substances on fetal health.
