The rupture of the prepubic tendon results in the loss of support of the ventral floor of the animal's abdomen. A pregnant, four-year-old Santa Inês breed was seen, complaining of apathy, progressive weight loss for ten days and prolonged pregnancy. On clinical examination, the abdomen was excessively pendulous, mild ventral edema between the udder and the umbilical scar, reluctance to stand up, udder displaced cranio-ventrally and with wounds, limited mobility, asymmetry of the pelvis, tachycardia and tachypnea. The presence of ketone bodies was detected in urinalysis. The viability of the fetuses was confirmed by ultrasound and the possibility of total rupture of the abdominal muscles was ruled out. Delivery was induced after eight days of hospitalization, with dexamethasone (20mg, IM, single application). Three days after the application of the corticoid, she went into labor, requiring obstetric maneuvers to remove the fetuses, as the sheep did not present abdominal contractions. The patient recovered, but as the clinical picture is compatible with rupture of the prepubic tendon, it was recommended that the animal be removed from reproduction to avoid problems for the sheep and lambs. It is concluded that gestational follow-up is indispensable for animals with this condition and that, through clinical evaluation, the diagnosis of this condition can be reached.
Prepubic tendon rupture may lead to the loss of pelvic floorsupport. A four-year-old Santa Inês ewe had been reported suffering fromapathy, progressive weight loss throughout ten days, and prolongedpregnancy. Physical exams showed an excessive pendulous abdomen, amild ventral edema between the udder and the umbilical scar (xiphoidregion). Also, the udder was cranially displaced and with hematomas.Other symptoms noticed were walking reluctance, pelvic asymmetry,tachycardia, and tachypnea. The urinalysis findings indicated the presenceof ketone bodies. The ultrasound examination confirmed the presence offetuses with normal development, and a potential rupture of theabdominal muscles was excluded. Eight days following its hospitalization,labor induction was carried out using dexamethasone (20mg, IM, singleapplication). She went into labor three days after the initial dose ofcorticosteroid. The ewe had difficulty expelling the lambs, making theirtraction necessary. Although the animal has recovered from its injuries,the clinical picture shows prepubic tendon rupture, and in order to preventfuture complications, the ewe is not going to breed anymore. The report ofthis case works as an alert to the possibility of the occurrence of thisaffection in ewes and demonstrates the need of parturition assistance inanimals with this condition, which can be diagnosed through clinicalevaluation
