Number of duck and its breeding facilities have been steadily decreasing for financial and social issues in Korea. Therefore, the ‘turning point’ forduck industry is strongly demanded. In this study, the questionary survey was carried out to provide backgrounds for developing policy and technologyfor duck breeding farms. The questionary survey aimed to investigate the information of operation strategy of farm, ventilation, cooling and heating. The total number of survey respondents was 74. In case of facility type, 55.4% of respondents stated they used greenhouse type, 31.3% forwinch-curtain type, and 2.7% for windowless type (mechanically ventilated facility). More than 85% of the facilities were using ‘natural ventilation’,it meant that these situation can restrict the not only environmental control but also the supply policy for ‘smart farm’ of the Government. 44.6% usedthe combination of the cross-ventilation method and roof-ventilation method for ventilation operation in summer season, and 31.1% followed only thecross-ventilation method. In case of winter season, 36.5% used the cross-ventilation method, and 33.3% used the combination of cross androof-ventilation, method. For the ventilation strategy, about 86.5% depended on farmer’s experience. In case of heating and cooling, 79.7% were usingkerosene heater for winter season, and 43.2% were using mist-spray for summer season, respectively. More than 75% stated that cooling and heatingstrategies were based on farmer’s experience. From the analyses of the survey results, a few proposals for developing policy and technology for duckbreeding farm was suggested.
