北京市种鸡场平养密闭式鸡舍环境因素观测分析

本文通过对北京市种鸡场平养密闭舍1986年夏至1987年春环境因素观测分析,指出该舍内气流速度、气流方向、光照时间及光照度等基本符合鸡的生理要求;但夏季舍内呈现高温、高湿,冬季呈现低温、高湿有待改进。经研究提出措施是:夏季可采用湿帘降温,冬季可根据温、湿度、氨气浓度综合控制风机运转等。

OBSERVATIONS AND ANALYSES OF THE ENVIRON MENTAL CONDITIONS OF THE CLOSED HEN HOUSE AT BEIJING HEN BREED FARM

The paper states the results of observation and analysis of the environmental conditions of the closed floor-managed hen house at Beijing Hen Breed Farm from the summer of 1986 to the winter of 1987. The factors to be studied are room temperature, room humidity, ammonia and bacteria content in the air, room air flow velocity and room illumination intensity.After observation, the velocity and direction of air flow and the duration and intensity of illumination in the raising room are all reached the level as requyied by the physiology of hen. Unfortunately, the room temperature and the room humidity within the raising room are both too high during the summer time and on the contrary, the temperature is too low and the humidity keeps too high during the winter time in the room.The author suggests to use the wet curtain system to lower the room temperature during the summer time and to control the room temperature, room humidity and ammonia content by suitable ventilation during the winter time.
