| dc.description | In the recent years poultry rising has become a growing and prospective
industry in Bangladesh. Poultry rearing can play a vital role in the country
like Bangladesh where most of the people are landless, disadvantaged and
devoid of formal education or skill to participate in income generating
activities. 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. 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. At present there are more than about
30,000 commercial broiler and layer farms are supplying 260 thousand
metric ton poultry meat and 5.21 billion table eggs per year (Rahman,
2003). The current investment in poultry sector is about 22 billion taka and
a total of about 5 million people are working presently in this sector
(Rahman, 2003). 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). Poultry can be an
important tool to fight poverty not only for this group of people but also for
the distressed women as poultry requires minimum land, short capital and
skill. Despite the special emphasis of the state on this sector, the
development of poultry industry is seriously threatened by the outbreaks of
acute contagious and fatal diseases. Among them Newcastle diseases (ND),
also known as Ranikhet diseases, is one of the major problems in the
development of poultry industry in Bangladesh. | en_US |
| dc.description.abstract | The study was designed to investigate the pathological conditions of NDV
in the small scale commercial broiler farms at different region in Dinajpur
district. The duration of experiment was 6 months from July, 2012 to
December; 2012.The objectives of the study were clinical sign, gross lesion,
microscopic lesion, and the prevalence of the diseases. Different organ
mainly proventiculus, intestine were collected, preserved and processed for
histopathological examination. The clinical signs were sneezing, caughing,
depression, torticolis of neck, white greenish diarrhea, and paralysis of leg.
At necropsy severe haemorrhages in the proventiculus, caecal tonsils,
intestine and trachea. Histopathologicaly in proventiculus distortion of the
normal structure of the tissue, globular destruction, haemorrhage and sever
epithelial layer destruction. Total 250 diseased and dead birds (From 35
farms) were examined out of which 135 birds were found to be positive for
NDV.The mortality was higher in nonvaccinated than in vaccinated birds, | en_US |
