Abstract: The appropriate use of disinfectants in poultry farm is an important and major component of a successful bio-security program. The objective of the study was to determine the most effective of all the disinfectant in reducing microbial load, the effect of time on disinfectant and the effect of organic waste on disinfectant. Salmonella organism place in a broth and the disinfectant reconstituted with distill water in 1:10 dilution was introduced. The opacity tube was used as a standard for clearing. Salmonella gallinarum was used to represent pathogenic gram negative bacteria commonly found in poultry farms. The first study is to determine the most effective of all the disinfectant in reducing the microbial load. The disinfectant used are phenol, gluteraldehyde and quaternary ammonium compound. The second study deals with the effect of time (0, 2, 4, 8 and 12 weeks) on the efficacy of disinfectants diluted to working concentrations. The third study determined the effect of organic waste on the concentration of freshly prepared disinfectants and 12 weeks old disinfectantsin the presence of organic waste. The result of the first study showed that the most effective of all the disinfectants under consideration is quaternary ammonium compound. While the result of the second study show that time affected the efficacy of disinfectant as freshly reconstituted disinfectant gave better efficacy than 12 weeks old disinfectant, against Salmonella organism. The result of the third study show that organic waste reduces the efficacy of disinfectant (p≤0.05) remarkably.
