| dc.description.abstract | This study was designed with a view to investigate the prevalence of poultry
diseases in sadar upazila of Dinajpur district of Bangladesh. The research was
conducted from September 2016 to August 2017. Commercial birds which were
registered for the diagnosis and treatment as well as the birds registered during
direct field visit, were considered as the experimental birds. A total Number of
245 clinically affected or dead birds were diagnosis for the disease. Along with
the postmortem lesion, clinical history of vaccination, flock size, previous history
of disease and clinical sings were recorded for the tentative diagnosis of the
disease. The common diseases encountered in birds were viral diseases 60.38%
(New castle disease 23.67%, Infectious Bursal disease 35.51%, Fowl Pox 1.2%),
bacterial disease 25.29% (Salmonellosis 6.53%, Colibacillosis 13.46%, Necrotic
enteritis 3.67%, Chronic respiratory disease 1.63%), Mycoplasmal disease
(Mycoplasmosis 8.2%) and parasitic disease (Coccidiosis 6.13%).In respect of
season the highest prevalence was found in rainy season (47.51%) followed by
summer season (35.48%) and winter season (17.21%). Among the infectious
diseases Necrotic enteritis was significantly (P<0.05) higher in rainy season
(3.26%) but Mycoplasmosis was significantly (P<0.01) higher in winter season
(4.49%) and other infectious diseases were not significantly differed among
seasons.Age had significant (p<0.05) effect on the prevalence of New castle
disease, Infectious bursal disease, Fowl pox, Salmonelloss, Nectrotic enteritis,
Coccoddiosis, but no significant (p>0.05) effect on the prevalence of
Collibacillisis, Chronic respiratory disease and Mycoplasmosis. It concluded that
viral disease are very high at study which is big problems to develop poultry
