摘要
为了探索黑龙江省散栏式泌乳牛舍存在的环境问题,试验采用现场测试的方法,测定了散栏式泌乳牛舍的温热环境和空气质量。结果表明:散栏式泌乳牛舍的平均气温为0.2℃,平均相对湿度为96.3%,CO2浓度为4 189 mg/m3,均不符合奶牛舍环境的行业标准。说明散栏式泌乳牛舍的通风量严重不足,而舍外围护结构的保温隔热能力差是牛舍内气温低、空气潮湿和污浊的根本原因,通风换气设施不完善、水气产生量大是泌乳牛舍环境恶劣的辅助原因。
To explore the environmental problems existed in the free -stall barns for lactating cows during winter in Heilongjiang province, a method of on - site test was used to determine the thermal environment and air quality environment of free - stall barns for lactating cows. The results showed that the average air temperature, average relative humidity and carbon dioxide concentration of free - stall barns for lactating cows were 0.2 ℃, 96.3%, and 4 189 mg/m3 , respectively, however, all of them were under the industry＇s environment standards of barns for dairy cows. The results indicate that the ventilation is not enough in the free - stall barns for lactating cows, while poor insulation capability of build- ing shell is fundamental reason of low air temperature, humid and foul air in the barns, and imperfect ventilation facility and high production of moisture are secondary reason of bad environment of free - stall barns for lactating cows.
