| dc.description | Household duck keeping has a significant contribution in the economy of rural
Bangladesh. There are about 44.12 million ducks in Bangladesh of which 85%
reared in rural households under semi-scavenging system (Ajnber and Mia, 2002).
Most of the ducks in Bangladesh (90-95%) are of native types (Ahmed, 1986).
Ducks are important source of nutritious food, source of income and therefore,
their rearing and production has became means of breaking out poverty trap of
resource for the poor small holds of low income countries (Pym et al., 2002). So,
duck farming is an important option of livelihood available to land less farmers
because of the fact that duck can exploit common feed resources in natural water
bodies, like wet and marshy lands, beefs, haors, rivers, cannels etc. Duck farming
is increasing in the recent days in Bangladesh and about 26000 duck farms have
already been set up in private sectors (FRYP, 1998).
Household ducks rearing has a significant contribution in the rural economy of
Bangladesh. The average annual income in different categories of duck raisers
ranged from Tk.79121 to Tk. 382667 (Khanum et al., 2005). Whereas, Huque and
Sultana (2003) stated that a farmer with 200 layers with or without hatchery may
make an annual profit of Tk. 55353 to Tk. 116722. But there are many constraints
for, the development of large scale duck farming either in the rural or urban areas
of Bangladesh. Among these, occurrences of diseases are the major hindrance for
the development of duck farming in Bangladesh and thereby causing significant
economic losses. The cause of mortality of ducks in Bangladesh were due to duck
plague (Baki et al., 1986, 1991; Das et al., 1988, 2005). | en_US |
| dc.description.abstract | Clinicopathological status of duck plague was investigated at different
upazila of Dinajpur district during the period from January to June, 2014.
The clinical features emphasiging the mortality and prevalence, necropsy
for gross morbid lesions, histopathological features were examined. The
farm and flock history, managemental aspects, vaccination status, nutrition,
etc. were recorded carefully. The data was collected and statistically
analysed. Farmer’s complaint’s about their affected birds were also
considered and emphasized. The average mortality rate was recorded as
14.42% and prevalence was 19.81%. The sick birds clinically showed
moderate to severe depression, ocular and nasal discharges, ataxia, dypsnia.
The affected organs were pathologically characterized as mild to moderate
congestion and haemorrhages; misshapen, ruptured cystic ova, and
histopathologically characterized as mild to moderate architectural
destruction, reactive cell infiltration. | en_US |
