北方农牧交错区一种大型双坡式奶牛舍温热环境的评价

Evaluation of thermal environment of a large dual-slope barn for dairy cattle in the agro-pastoral interlaced region of Northern China

为了评估北方农牧交错区奶牛舍的温热环境是否满足奶牛生产需要,试验对内蒙古西部农牧交错区一种大型双坡式奶牛舍内外夏冬两季空气温热环境指标进行了监测与评价。结果表明:所测奶牛舍夏季中午时段舍内温度较高,其他时间温热环境基本适宜;冬季舍内温度偏低。说明所监测奶牛舍夏季时温热环境基本满足奶牛生产需要,而冬季则应加强牛舍的封闭性以保证舍内温度。

To evaluate whether the thermal environment of the barn for dairy cattle could meet the productive requirements of dairy cattle in the agro -pastoral interlaced region of Northern China, the thermal environment indexes of inside and outside the large dual -slope barn for dairy cattle in summer and winter were monitored and evaluated in the agro - pastoral interlaced region of western Inner Mongolia. The results showed that the thermal environment of the monitored barn was suitable except higher temperature at noon in summer; the temperature inside the barn was on the low side in winter. The results indicate that the thermal environment of the monitored barn for dairy cattle can basieally meet the pro- ductive requirements of dairy cattle, in summer, but the closure of the barn should be strengthened to ensure the temperature inside the barn in winter.
