ABSTRACT
The treated waste water [Tww] from Helwan sewage treatment plant was used with and without dilution by tap water as only source of drinking of broiler chickens. The effect of Tww on sanitary condition as well as on immune response to vaccination against NDV and IBDV was recorded. It was found that the non diluted Tww contains heavy metals which are precipitated in muscles, organs and bones of chickens. The precipitaiton gradually decreased by dilution of Tww. The Tww had an immunosuppressive effect correlated with the rate of Tww dilution
