What effect does Oxytocin have on sows during the farrowing process?

Oxytocin plays a crucial role during the farrowing process in sows by causing uterine contractions. This hormone is released naturally during labor and is essential for the progression of the birthing process. It stimulates the smooth muscles of the uterus to contract, which helps in pushing the piglets through the birth canal and facilitating a smoother delivery. The rhythmic contractions induced by oxytocin also help in ensuring that the piglets are delivered successfully and efficiently.

Other options do not accurately represent the role of oxytocin during farrowing. For instance, while appetite may be affected by various factors during pregnancy and lactation, oxytocin is not primarily known for decreasing appetite. Similarly, oxytocin does not have a direct impact on increasing body temperature or enhancing immune response, which are related to different physiological processes. Thus, the significance of oxytocin in promoting uterine contractions makes it a vital hormone in the farrowing process for sows.
