Abstract

This study aimed to replace liquid foot pan in the poultry farm, with a novel model that is used more effectively in biosecurity program convenient with the workers in Egyptian farms that avoid foot pan. This novel model dry foot pan, semiliquid (wet) foot pan and floor mat that enabled the disinfectants to be worked for a longer time. In the present study authors are looking for a durable footbath, stable, fast, easily applied and log acting in the reduction of salmonellae. The efficacy of powder disinfectant (calcium hypochlorite powder, Halamid, Staldren, Virkon S and paraformaldehyde) were tested against salmonellae in a novel form of foot pan dry, semi-liquid and floor mat models. The disinfectants were diluted by calcium carbonate or sodium chloride powder in the dry form, surfactant in the semiliquid form and use of the sponge as a mat in the third form. Daily measurement of the active principle of the tested disinfectants and the log reduction of the Salmonellae were done. The dry form and semi liquid form of the Calcium hypochlorite was successfully effective for 10 days in dry form and 9 days in semiliquid form. However, Halamid and Staldren were successfully effective in dry form for 14 days and 17 days respectively, semiliquid form was worked for 21 day and 3 days and floor mat was effective for 21 days and 3 days respectively. Paraformaldehyde powder was also effective for 6 days in the dry form, but in the semiliquid form was effective for 10 days, floor mat was effective for 12 days. 5% Virkon S could be effective for 3 days in the dry form and semi-liquid form but only 2 days in the floor mat form.
