摘　　要：试验旨在研究不同频率喷洒抑氨菌液对笼养蛋鸡舍环境的影响。3间鸡舍分别饲有900只54周龄新杨褐、白羽（新杨绿、海兰灰）和海兰褐蛋鸡。试验1、2、3期分别按照3d1次、2d1次、1d1次的频率以0．5％比例喷洒抑氨菌液；每天4次记录温度、湿度、NH3浓度和CO2浓度，并记录每日风机开关时间，测定硼酸吸收液中氨氮浓度和生理盐水中细菌和真菌数量。结果表明：NH3浓度、CO2浓度、吸收氨氮浓度、细菌和真菌数量不同程度地受到鸡舍内温度、湿度、风机运行时长和测定位置的影响；各环境参数受测定时风机开关状态的影响；鸡舍内NH3浓度在1-3d内明显随鸡粪堆积时间的延长而升高；每天喷洒一次抑氨菌液能明显降低有害气体浓度。结果表明，笼养蛋鸡舍环境受多种因素的影响，每天喷洒1次抑氨菌液能明显改善舍内空气质量。结果表明，每天喷洒一次抑氨菌液能明显改善舍内空气质量。To study the effect of ammonia-inhibiting bacterial liquid through different spraying frequencies on environment of caged layers＇ houses. Three houses were selected with feeding 900 healthy Xinyang brown layers, white feather layers and Hy-line brown layers, respectively. Trial 1, 2 and 3 were carried out with spraying 0.5% ammoniainhibiting bacterial liquid every three days, every two days and every day, respectively. Temperature, relative humidity, concentrations of ammonia and carbon dioxide were determined; time of turning on or off and runtime of exhaust fans were recorded, concentration of absorption ammonia-nitrogen in borate absorption liquid and numbers of bacteria and fungi sampling by saline solution were determined each day. Results showed that concentrations of ammonia, carbon dioxide and absorption ammonia-nitrogen, numbers of bacteria and fungi were affected by temperature, relative humidity, runtime of exhaust fans and determination positions in layers house in varying degrees; environmental parameters were affected by running state of exhaust fans at that time; concentration of ammonia increased with overtime of manure accumulation in 3 days; ammonia-inhibiting bacterial liquid can decrease concentrations of harmful gases by spraying each day. These results indicated that environment of caged layers＇ house was improved by spraying ammonia-inhibiting bacterial liquid every day.
