| 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 poultry rearing.
The vast majority of the world's hungry people live in developing countries, where 13.5 percent
of the population is undernourished (WFP, 2015). 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. The industry in Bangladesh is expanding rapidly. A parent population of 5
million produces 52 million day old chicks a year and the annual growth rate is 15 to 20%.
Broiler meat production is currently at 2.2 million tones a year, with 300 million eggs produced.
The country has a population of 14 million people who need a daily protein requirement of 70
to 100 grams a day. Currently, the average poultry meat consumption is just one kilogram a
person a year, while just 28 eggs per person are eaten each year, (Peter, 2014). 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 schemed to investigate the prevalence, pathology, mortality and
clinical features of Newcastle disease in the small scale commercial broiler farms
at Bochaganj upazila of Dinajpur district during the period from January to June,
2014. A total 1950 birds (from 5 farms), among which 160 diseased and dead
birds were randomly selected, out of which 99 (5.35%) birds were found to be
positive for Newcastle disease. Thorough clinical and necropsy examination was
done and the characteristics clinical signs and gross lesions were recorded.
Different organs mainly proventiculus, caecal tonsil and intestine were collected,
preserved and processed for histopathological examination. The clinical signs of
the affected birds were sneezing, coughing, nasal discharge, laboured breathing
and torticolis, Broilers were inactive, weak and rough in appearance, greenish
watery diarrhoea occur severely. Nervous signs includes clonic spasm and
paralysis of the legs and wings. In this observation, the gross pathological lesions
were slight to severe haemorrhages in caecal tonsils, typical lesions were
proventricular haemorrhage, most commonly seen in the surface near the junction
with the proventriculus. Haemorrhages were found in the internal wall of
intestine, liver and lungs during post-mortem examination. Histopathological
lesions in the proventiculus were distortion of normal architecture of tissue,
globular destruction, severe epithelial layer destruction, haemorrhages and
congestion in the mucosa of proventriculus. The prevalence of Newcastle disease
in Bochaganj upazila was 5.35%. Mortality of Newcastle disease in nonvaccinated and vaccinated broiler flock was 20.76% and 4.6%, respectively. The
study indicates that birds of this areas were at high riskof NDV. Further studies
like serological, epidemiological and clinical examination can be done regarding
sex, age and climate to find out the real scenario of ND in the poultry sector at
Bochaganj. | en_US |
