内蒙古地区自然通风羊舍的冬季环境研究

Environment analysis of naturally ventilated sheep house in winter in Inner Mongolia

  • 摘要: 选择内蒙古赤峰市东郊的羊场对自然通风羊舍进行了冬季环境测试和分析。结果表明,夜间舍内平均温度为-2.8~1.2℃,平均相对湿度64.5%~73.5%;舍内的温湿度随舍外温湿度的变化而变化,但舍内温度比舍外高9~12℃,舍温平稳,舍内温差显著小于舍外;同时舍内风速、CO2、NH3浓度的测试表明,舍内空气质量在羊的适宜范围之内。不同朝向的羊舍舍内温、湿度有显著差异,南向羊舍舍温一般较东向羊舍高2~3℃;羊舍夜间全封闭时舍温一般比北窗敞开时高2~4℃。内蒙古地区采用自然通风羊舍,可在一定程度上改善羊只的饲养环境条件,减轻冬季严寒对养羊业造成的危害,但无任何供暖设备的羊舍尚不能完全满足冬季产羔的需求。

     

    Abstract: The environment of naturally ventilated sheep house was tested and analyzed at a sheep farm in Inner Mongolia in winter. The results show that the average indoor temperature and relative humidity of sheep house at night are -2.8~1.2 ℃ and 64.5%~73.5%, respectively. The indoor temperature and the relative humidity of sheep house are influenced by the outdoor temperature and the outdoor relative humidity. The indoor temperature is 9~12℃ higher than the outdoor one, and the temperature indoor fluctuates less than that outdoor. The air velocity, CO2 and NH3 concentration are suitable for sheep requirement. The results show that the indoor temperature and the relative humidity are obvious different when the sheep house orientation is different. The indoor temperature of houses facing to the south is 2~3℃ higher than that to the east. The indoor temperature of houses with the windows closed is 2~4℃ higher than that with the north windows opened. The naturally ventilated sheep house improves the environment situation to some degrees and alleviates the hazard of inclement weather to the sheep industry. But the house without any heating system can not meet the environment requests of lying lamb in winter.
