Monocephalic Sternopagus Tetrapagus Tetrapus Dicaudatus Monstrosity in a Surti Buffalo: A Case Report

Dystocia is the common sequel of foetal monstrosities. Teratologic abnormalities or developmentalarrests of the ovum, embryo or foetus may result in death or malformations of the antenatalindividual. The defect of conjoined twins is non-inherited teratologic, which arises from a single ovumdue to incomplete division during the primitive stage development and is monozygotic. Number offactors being influenced by genetic and environmental conditions may cause development ofconjoined twins. Various genetic factors were predicted to be responsible for the failure of theseparation of twins after the 13th day of conception (Srivastava et al., 2008). They are most commonin cattle but are seen rarely in sheep, pigs, dogs and cats and are exceedingly rare in horses.
