    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 in reared in research area.
