Abstract/ Executive Summary:

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 detaileo studies are needed to understand the role of etiology in these disease process which would help in designing logical control strategies.

Objectives:

This paper reports some important systemic and miscellaneous diseases and disorders in commercial poultry birds.

Methodology:

This study was conducted on the moribund and I or dead chickens submitted for the diagnosis of diseases at the Bangladesh Rural Advancement Committee (BRAC) Poultry Disease Diagnostic Centre, Nagapar Gazipur during one year period from January to December 2002. During this one year period, a total of 1751 cases of birds were diagnosed, of which 551 (31.47%) cases were recognized as systemic and miscellaneous diseases on clinical history and post mortem examination as described by Calnek et al. (1997). The influence of age, types of birds ( brooding, growing, pullet and layers ) and seasons on the occurrence of these disorders were analyzed.

Achievement/Findings:

It has been reported that excessive consumption of high-energy diets in birds• whose exercise is restricted in cages is considered to result in a positive energy balance and excessive fat deposition. The occurrence of this syndrome was recorded significantly (p < 0.05) at higher rates during hot weather of rainy (57.14%) and summer (35.71%) in comparison to winter (7.14%) which indicate that excessive fat deposition might be compounded by hot weather. 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 detaileo studies are needed to understand the role of etiology in these disease process which would help in designing logical control strategies.
