Keywords:
Water buffalo, dicephalus, Mozambique
Abstract
In March 2007, in Nicoadala – Quelimane, province of Zambezi, a calf of water buffalos (Buballus buballus) was borne with two heads. The calf was born within a herd of 320 water buffalos and lived one day. The body was send to the Central Laboratory of National Directorate of Animal Sciences (DCA) in Maputo. A team of this institution and Veterinary Faculty of Eduardo Mondlane University, made the study of morphological alterations present by dissecting the corpse after fixation by infiltration with formalin solution 10%. The findings of this study show that congenital anomalies involving head duplications can happen variably by individual and by species. The anomalies present in this case was of great severity that led to animal death within hours.
