A difficult birthing experience is medically referred to as dystocia. This condition may occur as a result of maternal or fetal factors, and can occur during any stage of the labor. Abnormalities of presentation, posture, and the position of the fetus within the uterus can negatively affect the temporal relationship between the birthing offspring and the maternal birth canal, thus causing serious problems.
There are many signs and symptoms of dystocia among ferrets, including:
Much like childbirth in humans, ferret childbirth is fraught with consequences should something go awry. Prolonged labor (lasting more than two to three hours), for example, can result in maternal and fetal death among ferrets. Likewise, abnormal fetal positioning resulting in gestation that is longer than 43 days, can result in fetal death.
Causes for abnormal or malpositioning in the birth canal can include abnormally small (less than three fetuses) or abnormally large litters, and abnormal levels of hormones in the mother ferret. Fetal head deformities can also lead to dystocia, as can poor cervical dilation and insufficient cervical contractions.
Diagnosis may first involve ruling out other causes for abnormal or difficult childbirth or labor such as a false pregnancy. Other tests that may confirm dystocia include ultrasound imaging (which may reveal the viability of the fetuses) or X-rays (which may help reveal the overall fetal size and whether fetal death has occurred in uteri).
