Abstract:

Combined effects of temperature, relative humidity and litter pH in the presence or absence of organic matter on the survival of S. typhimurium over time was studied. The litter (L: 30 cm x W: 25 cm x D: 6 cm aluminum trays filled with wood shavings) was inoculated with S. typhimurium at initial concentration of 4.8 x 107CFU/ml, then litter trays were placed in a room with microclimate similar to that of a naturally ventilated poultry house. The periodical measurement of S. typhimurium population in poultry litter in relation to the ambient environmental conditions revealed that: in the absence of organic matter; there was a non-significant (pS. typhimurium, a non-significant (pS. typhimurium population and a highly significant (pS. typhimurium. New management practice that will reduce litter pH and relative humidity should be considered in the control plans of Salmonellosis in poultry farms.
