| dc.description.abstract | The present study was conducted to identify the organisms
in feces of sheep and their effects on growth performance
of sheep at Gobindogonj Upazilla, Gaibandha. The samples
were analyzed to determine the total viable count,
prevalence of gram negative bacteria, Eschrechia coli and
Salmonella spp. The sheep were categorized into three (3)
groups namely group A, group B and group C according to
their body weight gain at same age. For the determination
of bacterial load a total of 45 samples were tested where
E.coli present in 20 sample and prevalence was 44.44%, (
group A- 60%, Group B -40% and group- C 33.33%), and
Salmonella spp was present in 11 samples and prevalence
was 24.44% (group A- 33.33%, Group B- 26.67% and group
C-13.33%). From this study the result represented that the
total viable counts/g feces in group A, group B and group C
were 9.8 x 106, 4.9x 104 and 3.4x 103 CFU/g sample
respectively, the E. coli counts/g feces in group A, group B
and group C were 4.24 x 106, 2.4x 104 and 5.5x 102 CFU/g
of sample respectively and Salmonella spp. counts/g sample
on group A, group B and group C were 3.2 x 103, 2.1x 102
and 1x 102 CFU/g feces respectively. The study showed
that group A had highest bacterial load (6.99 Log 10/g) and
group C had lowest bacterial load (3.53Log10/g).In
conclusion it is evident that E. coli and Salmonella spp was
successfully detected through different bacteriological agar
viii
media and biochemical reaction indicating the isolated
organisms were responsible for possible faecal pollution
and also a negative effect on growth performance of sheep
