A full term crossbred jersey cow at its fifth parity was presented to the Madras Veterinary College Teaching Hospital with the history of serosanguinous discharge from the vulva. Owner reported that the animal was straining and anorectic since two days. On general clinical examination, all the clinical parameters were in normal range. Vaginal examination revealed the presence of fetal forelimbs in the vaginal passage with head deviated laterally and the fetus in right dorso-ilial position. After correcting the position and postural abnormality a male dead fetus was relieved by simple traction. Further ex- amination of birth passage of the dam revealed the presence of second fetus in anterior presentation and dorso-sacral position with fore limbs extended and a female dead fetus was relieved by simple traction. On careful examination, the external genitalia of female fetus revealed prominent clitoris and the vagina were found to be a blind pouch. The present case was diagnosed as a dystocia due to twins and further, the condition of the female fetus was found to be to be freemartinism on clinical and karyotypic analysis. The present case will be discussed in detail.enVeterinary ScienceArticle
