| 摘 要： | 目的]为了解东北地区冬季育肥牛舍的环境状况。方法]对具有代表性的育肥牛采暖舍进行了为期5d的实地测量试验。所测得的温湿度、风速、CO2浓度、NH3浓度结果]为:舍内平均温度为12.4℃、湿度为83.9%、风速为0.10m/s、CO2平均浓度为3647ppm、NH3平均浓度为14.7ppm。由测量结果]可知:采暖舍内温度、湿度和风速均能很好的满足肉牛的生长和育肥的需要。但是CO2、NH3气体浓度稍高,可能是由于通风系统设计不合理造成的,但没有对牛的生长生活产生影响。由此可见,北方冬季采暖舍环境舒适度较高,可作为冬季肉牛舍有效的保温措施之一。结论]通过本试验的结果,为北方冬季肉牛舍的建筑设计及健康养殖技术的改进提供一定的技术依据。
