| dc.description.abstract | The present study was conducted to identify the bacterial load in feces of rabbit and to
identify their effects on growth performance of rabbit of Dinajpur Upazilla, Dinajpur.
The samples were analyzed to determine the total viable count, prevalence of gram
negative bacteria, Eschrechia coli and Salmonella spp. The rabbit were categorized into
three (3) groups namely group A, group B and group C according to their body weight
gain at same age and different feeding management. They reared in intensive system.
For the determination of bacterial load a total of 30 samples were tested. From this study
the result represented that the total viable counts/g feces in group A, group B and group
C were 1.2 × 104
, 2.4 × 106
, 3.5 × 107
CFU/g sample respectively, the E. coli counts/g
feces in group A, group B and group C were 2.5 × 103
, 5.5 × 105
and 4.5 × 106
CFU/g of
sample respectively and Salmonella spp. counts/g sample on group A, group B and group
C were 1 × 102
, 2.1 × 102
and 3 × 103
CFU/g feces respectively. The study showed that
group C had highest bacterial load 3.5 × 107
CFU/g (7.54 Log 10/g) and average body
weight these group rabbits 1 kg. In group A had lowest bacterial load 1.2 × 104
CFU/g
sample (4.08 Log10/g) and average body weight these group rabbits 1.5 kg. where the
prevalence of E. coli present in 13 sample was 43.33%, group A- 30%, Group B -40%
and group- C 60%, and the prevalence of Salmonella spp was present in 7 samples was
23.33%, group A- 10%, Group B- 20% and group C-40%. In conclusion, it is evident
that E. coli and Salmonella spp was successfully detected through different
bacteriological media and biochemical reaction indicating the isolated organisms were
responsible for possible fecal pollution and also a negative effect on growth performance
of rabbit reared in research area. | en_US |
