Abstract
Objective: A cross sectional study was conducted to estimate the prevalence of Infectious Bursal Disease (IBD) and Newcastle Disease (ND) in poultry of Narsingdi district, Bangladesh. Materials and methods: Post mortem of a total of 208 dead birds were done for the diagnosis purpose. Different poultry species included in this study included broilers, layers, pigeon, duck etc. Results: Among the examined birds, 38% were found to be affected with IBD, and 11% were affected with ND. Age of the birds for both IBD (19.95; 95%CI: 16-23) and ND (122.23; 95%CI: 98.62-145.83); and flock size only for IBD (1317; 95%CI: 1175-1460) was found significantly associated. The chicks aging between 16-23 days and flock size between 1175-1460 were found to be the most susceptible group to IBD, and adult poultry (98.62-145.83 days old) was mostly susceptible to ND. Conclusion: IBD and ND are highly prevalent in the study area. Therefore, it is necessary to conduct effective control measures to reduce the prevalence of these diseases. This study can help in designing appropriate control measures considering risk factors of these diseases. http://doi.org/10.5455/javar.2016.c181

Summary
It has no reservation that poultry industry in Bangladesh has greatly expanded over the years holding the greatest promise in affordable animal protein supply, food security and alleviation of poverty in both villagers and urban populace. Poultry industry is the fastest budding livestock sub-sector which has the annual growth rate of around 20 per cent in Bangladesh (Islam et al, 2014). Poultry rearing is an industry, superior to other sector in agriculture, has seen a tremendous development in the recent past and is an emerging agribusiness starting practically during eighties in Bangladesh. Previous studies indicated that poultry business is first on the list of currency of doublers among other financial transactions but poultry diseases are the major constraints for developing the poultry industry (Karim, 2003). Many studies reported constraints especially of disease and in particular viral disease have rendered this investment fearful and realistic to both organizations and individuals (Sainsbury, 2000; Islam and Samad, 2004; Musa et al, 2010)
