Abstract: Abstract: In order to ascertain the environmental condition of goat shed and its existing problems in South China, this study had been conducted for two years to detect and analyze the air environmental indicators in double-sloped airtight goat houses with windows and slatted floor, which was the most commonly seen type of goat house in Southern China, in summer in Jianghuai Region. The results showed that: ① daily mean temperature, relative humidity, airflow velocity, illuminance, noise and concentration of nitrogen and carbon dioxide in such goat houses in the hottest month in summer were 30.5℃、70.2%、0.16 m/s、99.45 lx、49.82 dB、1.98 mg/m3、0.060% respectively. All indicators met the required standards of environmental hygiene except for the daily mean temperature. ②Measurement in different sampling points of goat houses showed that characteristics of space distribution of each above-mentioned parameters were not very apparent. ③As outside environment changed, daily mean temperatures and relative humidity in the sampling points also changed apparently. The shift was relatively steady in January, while temperatures in rainy days dropped fairly significantly (6.9℃). Average temperature difference between days and nights during the trial period was 2.3℃. Average indoor and outdoor temperature difference in the goat houses was 1.8℃. ④ Daily and monthly concentration of nitrogen and carbon dioxide in the sampling sites shifted slightly. ⑤There was a significant negative correlation between temperature and relative humidity of the air in the sampling sites (r=-0.9818, P<0.01), while a significant positive correlation was detected between the concentration of nitrogen and the temperature and relative humidity of the air (r=0.8702, P<0.05). It is recognized based on the comprehensive evaluation that microclimatic environment of double-sloped airtight goat house with windows and slatted floor is basically in accordance with biological characteristics of environmental hygiene and goats. Thus, this type of goat house is suitable to be promoted and applied in Jianghuai Region, and it is only necessary to take certain measures to lower the temperature in the houses in hot summer weather.
