WehkeS.N. 52013135Diseases and infections have always been a major concern to intensive poultry production industry. Pathogen contamination of farming environments can be prevented using proper health care products such as disinfectants. This study evaluated the efficiency of commonly used disinfectants against bacteria occurring in intensive poultry farming environments in Imo State, Nigeria. The efficacy of six commercial disinfectants namely; Izal®, Z-germicide®, Diskol®, Virkon®, Vox® and CID 20® in reducing the number of micro-organisms was assessed. Among the tested disinfectants, Virkon® (oxidizing agents) was the most efficient, reducing the micro-organisms by 95%. The in vitro test carried out to verify the effectiveness of disinfectants did not consider the adverse conditions found in the poultry farms. Therefore, the evaluation of the efficacy of on-farm reconstituted disinfectants over time was also carried out. The results indicated that efficacy of all the disinfectants was reduced during the afternoon. However, efficacy gradually increased during the evening for all the disinfectants but not as much as was observed in the morning. Temperature, it seems affects the activity of the disinfectants against the bacterial organisms.]]>Allen, M.J., G.F. White and A.P.
