title: Congenital duplication of the caudal region (monocephalus dipygus) in a kid goat.
abstract: A case of congenital duplication (monocephalus dipygus) in a goat is described. Two pelvis and four pelvic limbs were observed in the kid. Conjoined or fused symmetric twins were diagnosed. Associated abnormalities were cleft palate and anal atresia. Most of the classically recognized teratogens were ruled out by history and serology. However, progenitors were related in the second degree. Thus, genetic factors could be suspected in this case. To the authors' best knowledge, this is the first report of monocephalus dipygus in a goat.
