Abstract
Poultry industry has been fully integrated in Sri Lanka during last two decades and the overall production and consumption has increased. With the improvement of the industry, occurrence of diseases has increased and Salmonellosis is reported as one of the prevalent diseases. Fowl Typhoid (FT), also known as Klein’s disease, is caused by Salmonella gallinaruni , and is host specific for chicken and turkey. FT creates serious economic losses to producers, since it effects on any stage of chickens. Chicks infected through trans- ovarian transmission experience to high mortality. Vaccination against FT is only allowed for commercial layers, in Sri Lanka, but with strict post vaccination monitoring. Hence, poultry producers are on constant look out for better and innovative remedy. The bacterium is fairly resistant to normal climate, surviving for months, but is susceptible to normal disinfectants (McMullin, 2004). Therefore, prevention of microbial contamination is one possible solution and can be achieved through proper disinfection which is one of the important practices in every unit of poultry industry. Most importantly, disinfection offers long-term benefits and has combined properties of detergents and sanitizers. Disinfectant chemicals act to disrupt cellular structures or processes in order to kill or eliminate microorganisms. A number of different chemicals have been commercialized as disinfectants and those can be grouped as alcohols, halogens, quaternary ammonium compounds, phenolic, aldehydes, and oxidizing agents and other. Not all disinfectants are suited for every situation. Therefore, evaluation of different disinfectants against infective agents may result benefits. Many disinfectants of similar composition ai e sold under different trade names (Saif, 2003). Therefore, five farm-use-disinfectants which represent five chemical groups were selected and tested to identify most effective concentration- contact time combination of highest effective disinfectant, for Salnionello gallinarum.
