Buffalo Bulletin (October-December 2017) Vol.36 No.4 695 ABSTRACT The present report describes a case of dystocia due to congenital hydrocephalic fetus with incomplete dilatation of the cervix in an aborting pluriparous Murrah buffalo in its last trimester of gestation. The buffalo was successfully handled for dystocia with an uneventful recovery. Keywords: Murrah buffalo, cervix, dystocia, hydrocephalus, pluriparous INTRODUCTION Dystocia due to fetal hydrocephalus is reported in all domestic farm animals (Arthur et al., 1996) and rarely seen in buffaloes (Kumaresan et al., 2003). Congenital hydrocephalus condition has been described in Indian buffaloes by Pandey et al., 2010. Hydrocephalus is an abnormal accumulation of excessive cerebral fuid in cranial cavity (Purohit et al., 2012). There are two types of Hydrocephalus: Internal hydrocephalus due to collection of fuid in the cerebral ventricles, and external hydrocephalus due to collection of fuid in the sub arachnoid spaces (Noakes et al., 2009). Internal and external hydrocephalus may also occur in combination (Roberts, 1986). Hydrocephalus is assumed to arise from disturbances in normal circulation of cerebrospinal fuid resulting from its altered production or absorption (Fride, 1975). An autosomal recessive gene has been reported to be linked with hydrocephalus condition (Roberts, 1986) and it may get exacerbated in its manifestation by a coexisting hypo-vitaminosis (Jubb and Kennedy, 1970). The present communication reports successful management of a case of aborting hydrocephalic fetus causing dystocia due to incomplete dilation of cervix in a pluriparous Murrah buffalo.
