Important systemic and miscellaneous diseases associated with morbidity and mortality in commercial poultry in Bangladesh

Abstract

History and necropsy methods were used to study the systemic and miscellaneous diseases among 1751 moribund and dead commercial chickens submitted for diagnosis at the BRAC Poultry Disease Diagnostic Centre, Gazipur, during one year period from January to December 2002. Of the 1751 chickens examined, 554 (31.64%) birds were affected with 15 different types of systemic and miscellaneous disorders. These included omphalitis (5.25%), enteritis (9.08%), pneumonia (0.80%), egg peritonitis (2.74%), egg bound (8.28%), salpingitis (0.40%), malabsorption syndrome (0.17%), ascites (0.74%), visceral gout (0.86%), neoplastic disease (1.54%), hydropericardium-hepatitis syndrome (0.23%), big liver and spleen disease (0.06%), fatty liver-haemorrhagic syndrome (0.80%) and cannibalism (0.17%). The possible etiology, single and concurrent occurrences influence of age and seasons on the occurrence of these disorders are described and discussed. It may be concluded from this study that the systemic and miscellaneous disorders are associated in the high rate of morbidity and mortality in commercial poultry with possible complex etiology. Thus further detailed studies are needed to understand the role of etiology in these disease process which would help in designing logical control strategies.
