Investigation of Proportionate Prevalence of Newcastle Disease in Chicken, Pigeon and Duck at Selected Veterinary Hospitals in Bangladesh and India

Abstract

A prospective study was conducted to evaluate the prevalence of Newcastle Disease (ND) in pigeon, chicken and duck at selected Veterinary Hospital, in Bangladesh and India during December 2015 to May 2016. A total of 245 ND cases were identified by anamnesis, manifesting signs and clinical and physical examination and occasionally postmortem examination. The aim of the study was to estimate proportionate prevalence of ND in pigeon chicken, duck and investigate the distribution of ND according to different factors. Information about species, age sex, and season’s time required showing clinical signs, knowledge about ND vaccine were composed by extensive cross-questioning through pre-structured questionnaire over the owners. The proportionate prevalence was found higher in pigeon (58.9%) irrespective of study placements. The prevalence of ND was highest in summer season (50.6%) and lowest in rainy season (10.2%). Younger birds 20 to 65% are more susceptible to ND irrespective of age. The proportionate prevalence in male and female was 14.2 to 53.8% and 16.7 to 60.9%, respectively. Among the body system digestive system was more affected (42.04%) than the nervous system (20%).
