| dc.description | Bangladesh is an agricultural country with a large number of domestic
chickens and ducks. About 80% of the total population of 140 million is
living in the 68,000 villages of Bangladesh, and almost each and every
village home holds 6-7 chickens. It is estimated that there are about 153
million chickens in Bangladesh. There are about one lac poultry farms in
Bangladesh, of which 20% rearing 1000 to 50,000 birds and remaining
80% are small in size with 100 to 1000 birds. Currently there are about
130 hatcheries (65 hatcheries with breeding farm) in Bangladesh, with
two million broilers and 0.3 million layer parent stock which producing 4
to 5 million commercial day-old-chicks per week. The commercial broiler
and layer farms supplying about 0.2 million metric ton of poultry meat
and 5210 million table eggs per year in Bangladesh. (Samad, M.A. 2005). | en_US |
| dc.description.abstract | The present research work was conducted to detect and characterize the bacterial
contaminants in the poultry litter and feed, For this study samples were collected
from the different broiler farms namely Israful Poultry Farm, Basherhat; Harun
Poultry Farm, Basherhat; Tarikul Poultry Farm, Basherhat; Vai-Vai Poultry Farm,
Kornai (Katapara), under the district of Dinajpur. Six litter samples and equal
number of feed samples were collected from each poultry farm. A total of 48 samples
were collected and brought to the Laboratory of Microbiology for laboratory assay.
The amples were inoculated in to nutrient broth and nutrient agar media followed by
culture on selective media such as Eosin Methylene Blue agar, MacConkey agar,
Brilliant Green agar, Salmonella-Shigella agar. Biochemical properties of the isolates
were also studied and reaction in TSI agar slant was observed. MIU test, MR test
and VP test etc. were also performed. Gram's staining techniques were also
performed. Total numbers of 48 samples were examined and 30 samples were found
to be positive for E. coli and the prevalence of EF. coli in this study was 62.50 %.
Total 9 (37.50%) of feed samples were found positive for E. coli within 24 tested
samples where as 21 (87.50%) of litter samples were positive within equal number of
tested samples for this bacteria. On the other hand 23 samples were found positive to
Salmonella and the prevalence of Salmonella in this study was 47.92 %. Total 7
(29.17%) of feed samples were positive for Salmonella within 24 tested samples
where as 16 (66.67%) of litter samples were positive within equal number of tested
samples for this bacteria. The widespread occurrence of FE. coli and Salmonella in
poultry feeds and litter reinforces the need for effective control measures, biosecurity, hygiene in processing and handling of feeds and litter. | en_US |
