| dc.description | Bangladesh is one of the most densely populated country in the world with 152.5 million
people (P.D, EU, 2011). About 31.5 percent people live under malnutrition (Brad Field, -
2010). The average quantity of protein uptake by people is insufficient per head per day
where as desirable requirement is decreasing daily per head day by day. Poultry
production is an easy and efficient way of producing animal protein. With less capital
investment relatively more profit could be earned by producing poultry. The poultry
population of Bangladesh has increased from around 71 million in 1986 to around 188
million in 2006, an increase of about 164 percent in 20 years (FAO, 2008; BBS, 2006).
The increasing demand and economic aspect has created a lot of interest among the
people to raise poultry either through backyard or intensive commercial farming system.
There is a vast need for developing poultry farming both in rural and urban areas for the
fulfillment of protein supply. But poultry farming in Bangladesh faces various types of |
hindrance among them coccidiosis is considered as one of the most serious problems for
poultry development. Commercial poultry production has increased manifold during last
decade but at the same time, coccidiosis which was primarily a sporadic disease in 1976
has become a diseases of high occurrence in 1986 (FAO/WHO/OIE, 1976, 1986). The
coccidia of the genus Eimeria is an obligatory intracellular parasite with a complex life
cycle. The availability of a suitable host is probably the only limitation to the distribution
of coccidia. Eimeria is distributed throughout the world (Macpherson, 1978). | en_US |
| dc.description.abstract | The study was designed to investigate the pathological conditions of avian
coccidiosis in the small scale commercial broiler farms at different region at
Dinajpur districts in a short six month duration starting from July, 2012 to
December, 2012. Total 338 diseased and dead birds (From 100 farms) were
examined out of which 44 (8.32%) birds were found to be positive for coccidiosis.
A thorough clinical and necropsy examination was done and the characteristics
clinical signs and gross lesions were recorded. The clinical signs of the affected
birds were bloody diarrhea, anemia, depression, ruffled feather, reduction of feed
and water intake, drooping wings. At necropsy, enlargement and discoloration of
caecum with numerous hemorrhage spots, blood mixed intestinal contents in the
intestinal lumen, reddish to brown contents in the intestinal lumen, hemorrhage on
the intestinal wall, and profuse hemorrhage on intestinal mucosa were found.
Different organs mainly caecum and intestine were collected, preserved and
processed for histopathological examination and histpathologically, distortion of
normal architecture of intestine and desquamation of lining epithelia, formation of
tissue debris on the intestinal mucosa and necrotic cells infiltration in the lamina
proprea and submucosa, degeneration of epithelial cells, glands, intestinal villi
and Infiltration of inflammatory cell in the musculature were also present. | en_US |
