Abstract
The prevalence of diseases in broiler encountered in commercial broiler
farms at Dinajpur district of Bangladesh was pathologically investigated.
The course of the study was one year from September, 2009 to August,
2010 under the Department of Pathology and Parasitology, Hajee
Mohammad Danesh Science and Technology University, Dinajpur. The
diagnosis of different disease conditions was done based on history,
clinical signs, characteristic gross morbid lesions and histopathological
study. In the present investigation, a total of 264 dead birds were
collected for necropsy from different broiler farms. The highest
proportional incidence of the diseases in broiler in the present
investigation was recorded 25.75% which was due to Infectious bursal
disease (IBD). This was followed by Newcastle disease (17.72%),
Colibacillosis (14.01%), Coccidiosis (8.71%), MC complex (8.71%),
Salmonellosis (7.57%), Aspergillosis (4.92%), Deficiency disorders
(4.92%), Aflatoxicosis (4.54%) and Miscellaneous disease conditions
(3.40%). The findings indicate that Infectious bursal disease (IBD) is the
major disease problem in broiler farming at Dinajpur.
Description
Poultry industry is the most promising sector in Bangladesh which will
not only generate employment opportunity but also encourage the
unemployment youths to take up this type of farming as a means of self employment. Now a day, the poultry farming is a popular enterprise in
every body. This poultry is providing animal protein for our large people.
Protein is the most important constituent of humans' food. Animal protein
is required for promotion of growth, disease resistance, body
maintenance, mental development etc. We get animal protein from milk
and its by-products, meats, eggs and fishes. Poultry meat contributes
approximately 38% of the total animal protein supplied in Bangladesh
(FAO, 1999). Broiler meat is one of the major sources of animal proteins. It
is calculated that in our country total demand of meat per year is 6.40
million metric tons but production is only 0.62 metric tons, i.e., deficit is
around 90.31%. In 1998-99, meat production was 515 thousand metric tons
and estimated target till 2010 is 1177 thousand metric tons (DLS, 1999).
