【 摘 要 】

The objective of the present study was to evaluate soil collected from a laying-hen farm and bird manure according to the season of the year and sampling site. Soil samples were taken at the poultry facility wall and at the distances of 15 m and 45 m from the building. Bird feces samples were collected inside the poultry house at the entrance and at 1/4 and 1/2 length of the building. Soil and bird feces samples were evaluated by bacteriological qualitative and quantitative analyses. The largest bacterial load was determined in the samples taken at the poultry facility wall in December/January. Soil microbial contamination degree was low. The highest bacterial count in bird manure was found in the samples collected at 1/2 length of the hen house at the end of December/January. The qualitative study of bird feces showed the presence of E. coli bacteria all through the research period and Enterobacter spp. in the samples taken from July until September. Microbial contamination of soil environment and bird feces is most likely to be affected by winter period as at that time the highest microbial population can be determined. This fact may be linked to the prevailing climatic and microclimatic conditions.
