In this study, environmental new feeding and management system that are suitable for hot and cool water supply and floor heating system was developed and analyzed the effect for productivity and meat quality with supplying hot water in winter, the results were as follow as. HWSS was not affecting improvement with broiler productivity in initial time. Supplying hot water made the temperature inside broiler barn not go down rapidly as time went by from former term to latter term and continuous supplying hot water made boiler be adapted properly to the temperature and humidity of breeding environment that was requiring at its own growth phases. With unsaturated fatty acid / saturated fatty acids, HWSS was higher in broiler breast but CWSS was higher in the leg. With AST, ALT in blood, HWSS is higher than CWSS but with neutral lipid, protein, glucose, albumin, cholesterol, HWSS is higher than CWSS. Water circulation heating system gave an impact on meat quality and PH showed a higher in CWSS system. Also, redness and yellowness of the meat color was confirmed to be greater in HWSS. It was proved that the temperature difference of drinking water affected farm productivity, the blood and flesh quality, therefore, that could be estimated to be utilized successfully, if that should be used appropriately for productivity improvement according to the week-old of growth phase.
