Abstract: Objective To monitor the environmental factors of experimental minipig facilities in Beijing and provide the basic data for local environmental and housing standard setting for experimental minipigs. Methods Examinations were conducted according to the appendix A-H of National Standard in Experiment Animal Environment and Facilities (GB14925-2001). The environmental factors, such as temperature, humidity, work-lighting, animal-lighting, noise, airflow velocity, ventilation, fallen bacteria, air cleanness, pressure, ammonia contents (dynamic), in 5 conventional and 3 barrier facilities, were examined. Results All the environmental factors were controlled at the range set by the National Standard (GB14925). Conclusion The environmental factors controlled in minipig facilities in Beijing meet the GB14925-2001, and it is necessary to give much more attention to the environmental requirements of minipigs in different growth stages.

摘要： 目的检测北京地区实验用小型猪设施环境因子控制状况,为制定北京市实验用小型猪环境设施等级标准提供基本数据。方法GB14925-2001附录A～H规定的检测方法。结果普通环境小型猪设施5个,7次静态检测,3次动态检测。屏障环境小型猪设施3个,3次静态检测。检测指标包括温度、相对湿度、工作照度、动物照度、噪声、气流速度、换气次数、落下菌、空气洁净度、压力梯度、氨浓度(动态)等环境因子。检测结果基本控制在GB14925-2001要求范围内。结论北京地区实验用小型猪设施环境控制基本符合国家标准的要求,现在没有小型猪普通环境及屏障环境的国标与地标,但且忽略了小型猪不同生长阶段对环境因子的特殊要求。
