Xifópagus cattle in a slaughter line in Eastern Amazon, Brazil
Keywords:
Congenital defects, Hereditary diseases, Ruminants, TwinsAbstract
This study reports a case of xiphopagus twins (thoracopagus) identified in a slaughterhouse in southeast Pará. During the slaughter inspection line, one of the animals was identified with advanced twin pregnancy and the fetuses were united by the thoracic cavity. Fetuses with this type of duplicity are called Siamese or Xiphopagus. This condition is a rare congenital alteration often considered of undefined etiology, and may be the result of and genetic defects, infectious agents, or environmental factors. The fetuses presented homogeneous and symmetrical morphology and were two equivalent individuals, both males. The report of anomalies, such as the one identified in the fetuses, allows monitoring the occurrence of similar cases, in addition to identifying and reporting possible hereditary defects in cattle.
