Evaluation of microbial contamination of feces and soil on a laying-hen farm depending on sampling site and season

Abstract: -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 ¼ and ½ length of the building. Soil and bird feces samples were evaluated by bacteriological qualitative and quantitative analyses. The largest bacterial load wa… Show more

“…The type of the house has direct effect on hygienic status of quails, as the different housing facilities (feeders, drinkers, litter/wire floor, equipment's) shedding different number of microorganisms. The higher feed, water, and litter bacterial contamination were recorded at the 4 th week of the study duration in FS than CS, a result that agreed with (Trawińska et al, 2016)they reported that the highest bacterial count in the litter was detected at the late rearing period of birds. The significant increases in bacterial load (TAB, E.coli, and TFC) in feed, water, litter, and nasal swabs were from living birds reared on FS might be due to open feed troughs, and drinkers that easily to be contaminated with litter, birds, dust, and fecal matter (Ezekiel et al, 2011).…”

“…This finding is in agreement with an investigation that reported high heterotrophic bacteria population in poultry farms in Ilorin, Kwara State [15]. However, the total heterotrophic count in our study is higher than the previously reported count in faeces of poultry birds located in some farms in Ogbomoso, Oyo State, Poland and Bangladesh [16][17][18]. This high count across the investigated farms could be due to poor environmental practices around poultry litter [18].…”

This high count across the investigated farms could be due to poor environmental practices around poultry litter [18]. It could also indicate that poultry feed or water is contaminated by large pool of commensal and opportunistic bacterial species [15].…”

“…This phenomenon could be due to a lower concentration of antibiotics used by the farmers, the potential antibiotic resistance capability of E. coli , and other possible management (feed and water troughs) and environmental sources (soil, water, scavenging feed resource) of bacterial contamination. Soil, water, and air have been reported as high-risk sources of E. coli contamination in poultry farms, and these sources may be affected by location, season, and agroecology [ 49 , 50 , 51 ].…”
