Congenital Malformations in Bovine

Abstract

The paper documents congenital malformations in bovine presented during last 15 years. An overall
incidence of 0.4% of bovine congenital malformations was recorded. The percentage of malformation was
higher in male calves (54.72%) than female calves (44.84%). Highest prevalence of congenital
malfonnations (49.4%) was recorded in cross bred Jersey calves followed by 30.4% and 19.76% in cross
bred Holsteins and local non- descript calves, respectively. Congenitally defective calves were born more
to primiparous dams (56.24%) than to pleuriparous dams (43.32%). Still born defective calves recorded
were 7.6%, where as only 5.3 % cases were born with dystocia. Highest number of congenital defects
(31.16%) was related with digestive system with Artesia ani as the single most prevalent deformity
(13.68%) among all recorded defects. Only 3.04% udder defects were recorded in Primiparous heifers.
