Context: Congenital defects can evolve from abnormal genetic make-up or from agents associated with the fetal environment or their interaction. The frequency of individual defect varies depending on species, breed, body system, geographic location and season. It is important to identify the causes of congenital defects and their possible solution as they hamper the economic benefit of the farm. Objectives: The present study was conducted to identify the congenital defects and to determine its prevalence in calves and kids. Materials and Methods: Gross observation and some physical examinations were applied for the presumptive diagnosis of congenital defects in calves and kids. Results: Thirty-two (32) ruminants (calves 29 and kids 3) were found to be affected with different congenital anomalies from January’ 2014 to June’ 2014 in thirteen different selected upazila of Bangladesh. The highest number of cases were recorded in Begumganj upazila in Noakhali district which was 18.75% of the total cases. Among the different congenital malformations atresia ani (58.62%) was recorded as the most prevalent, followed by bent leg (10.34%) and dermoid cyst (10.34%). The digestive system was observed to be the most susceptible (65.52%) to congenital defects than all other systems of the body while ocular system was found to be the least susceptible (13.79%). The study also revealed that 20.69% of studied animals were prone to be affected with congenital defects in Musculo-skeletal system. Conclusion: Different types of congenital defects involving various systems occur in ruminant where Atresia ani is the most prevalent congenital defects in calves and kids. Further experiment should be continued to explore the risk factors that leads such type of defects development and economic losses in farm animal.
