According to the extension of the anomaly, duplicated cases are classified as monoceophalus tripus dibrachius, monocephalus tetrapus dibrachius and cephalotho- racopagus. A newborn five-legged male kid was referred to the veterinary teaching hospital of Shahid Bahonar University of Kerman, Iran. In ventrodorsal radiography, normal pelvic symphysis was not observed between middle and left or right limbs. Necropsy findings included duplication of the bony pelvic girdle, alimentary tract from the jejunum downward, bladder and urethra. We hereby describe the first report of monocephalus tripus dibrachius in a kid goat. Key words: Duplication – Monocephalus – Tripus – Dipygus – Kid goat INTRODUCTION Embryonic duplications as congenital abnormalities have been reported in small ruminants since 1916 (Dennis, 1975). It is believed that they result from errors happen- ing during development (Noden and de Lahunta, 1985) and form a graded series from slight duplication to near-separation of two individuals (Hiraga and Dennis, 1993). Dipygus is a kind of duplication in which the caudal region of the body has been affected and, according to the extent of the anomaly, has been classified as monoceophalus tripus dibrachius, monocephalus tetrapus dibrachius and cephalothoracopagus (Hiraga and Dennis, 1993). This anomaly has been reported frequently in cattle (Abt et al., 1962; Hiraga et al., 1989; Hiraga and Dennis, 1993; Leipold, 1972; Shojaei et al., 2010; Thakur, 1988) and sheep (Dennis, 1975; Doijode et al., 1992; Hiraga and Dennis, 1993), but not commonly in buf- falos (Antoine et al., 1997; Thakur, 1988), and occurs very rarely in horses (Asquith and Sharp, 1979), dogs (Mazzullo et al., 2007; Nottidge et al., 2007) and cats (Seavers, 2009). As far as our knowledge goes, only three cases of similar anomalies in goats have been reported previously (Corbera et al., 2005; Mitra et al., 1994; Otiang’a-Owiti et al., 1997). In this paper, we present a case of dipy- gus which according to the available literature is the first description of monocephalus tripus dibrachius in a kid.
