Development of Environmental improvement system of Poultry buildings by Air conditioning and Drinking water

Abstract..A new feeding and management system that is suitable for cool water supply and air conditioning system was developed and analyzed the effect for productivity and meat quality. The cage area is 273m² and the air-to-water heat pump with 20RT capacity was used for heating and cooling. An electric hot water boiler was used for the control. . Heating load such as, heat pump capacity, heating capacity, heat storage tank, and drinking water tank capacity was determined by the case size. HWSS(Hot water supply system) 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(Cool water supply system) 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
