개요
Most of broiler houses in Korea have the trouble of environmental control such as suitability, stability, and uniformity of internal climate, resulting in serious on chickens. Accordingly, it is very urgent to develop optimum designs of naturally and mechanically ventilated broiler houses for korean climate. In the study, the internal climates such as temperature, humidity, dust, ammonia gas, and air velocity were measured at a naturally ventilated broiler house. The data were collected during summer season including local weather data. It was found that the difference between measured and optimum air temperatures was 14.0oC in maximum during the summer time. The daily maximum range of internal averaged air temperature was found 10.5oC while the uniformity was 5.2oC in maximum. The maximum, average, and minimum internal averaged relative humidity were 89.3%, 73.7%, and 49.2%, respectively while locally measured were 95.1% and 47.2%, respectively in maximum and minimum. Considering Temperature-humidity index, during summer season, over 97% of totally rearing period was shown that counter pln is needed for thermal stress while it was very dangerous situation for 22% of the rearing period. The ammonia gas and dust concentration were seriously affected by the broilers activity, growth level, and relative humidity.
