Abstract

Although the occurrence of dystocia in swine is generally low, it is usually associated with fetal static presentation or secondary uterine atony. This manuscript presents two unusual cases of dystocia in pigs. The first case describes a dystocia associated with persistent hymenal membrane, detailing its resolution and subsequent success during the delivery process. The second case reports a dystocia caused by primary uterine inertia in a non-toxic female, outlining its progression and pharmacological treatment while preserving maternal integrity. Both cases illustrate potential obstetric management approaches in sows under conditions that may occur in extensive or semi-extensive production systems practiced by small producers.
