| dc.description | Poultry is considered as an important source of animal protein all over the world. The
production and consumption of eggs and poultry meat has been increasing worldwide
over the last three decades as the consumption of eggs has doubled and that of chicken
meat has tripled (Jordan and Pattison, 2001). In Bangladesh, poultry contributes a
major share of animal protein simply because of the limitations and religious taboos in
case of pork and beef. Bangladesh is a country the people of which consume the
lowest percentage of protein than the minimum requirements because of inadequate
supply of protein-generating food products. Poultry meat and eggs are two major
sources of animal protein. The average per capita availability of meat and eggs
are 12.51 gm/day and 0.485/week, respectively against the minimum requirement
of 120 gm/day and 2.0/week (BBS, 1995). Each person should take 56 kilograms of
meat and 365 eggs every year. But in Bangladesh, per head intake of meat is only
11.27kg and egg 30 per year. As a result, people suffer from malnutrition. Poultry
meat and eggs provide approximately 38% total animal protein in the country (FAO,
1999). The country’s pervasive poverty may limit the number of people who can
afford to consume chicken as suggested by the simple relationship between per capita
GDP and chicken consumption. If population growth continues at this rate, protein
deficiency will rise ( Dobson and Quarder ,2005). The magnitude of the contribution
of the livestock sub-sector to the country’s gross domestic product (GDP) is 3.1
percent and to agricultural GDP it is about 11 percent. | en_US |
| dc.description.abstract | This study was carried out to evaluate the seroprevalence of Infectious Bursal Disease
Virus (IBDV) antibody with clinico-pathological investigation in different small scale
commercial broilers in Dinajpur. The clinical manifestations of the affected flocks
were anorexia, depression, ruffled feathers, diarrhoea and death. Swollen, soft and
edematous with yellowish discoloration bursa of fabricious were observed in
pathological investigarion. Petechial and ecchymotic haemorrhages were also observed
in the leg and breast muscles. Bursae of fabricius were collected aseptically and
were used for histopathological investigation. Mild to heavy necrosis and
depletion of bursal follicle and inflammation of follicular septa were found on
histopathological investigation. Inoculum were inoculated on the CAM route of 10
days old, 10 embryonated chicken eggs. Mortality of the one embryo was observed as
early as 48 hours post infection .While mortality of the other embryos occurred between
days 3 to 6 of inoculation. This indicated that IBDV causes mortality in inoculated
embryo through CAM route. A total of 90 broilers were randomly sampled for sera
collection. The indirect Enzyme Linked Immunosorbent Assay (ELISA) was the
technique used for antibody detection. The result showed the presence of IBDV
antibody in 25 (27.78 %) of birds evaluated while 65 (72.22%) were negative. Most of
birds show seronegative but the antibody level is very low that’s might be
unvaccinated or ineffective vaccine used resulting protective antibody level is not
increased. So the birds might be infected any time with IBDV and shows high
mortality. | en_US |
