摘　　要：通过监测蛋鸡舍和育成鸡舍内温度、相对湿度、NH3浓度和自然通风情况，探究蛋鸡在不同生长阶段NH3浓度的积累特征。结果表明，试验蛋鸡舍和育成鸡舍中NH3浓度分别为（1．94±0．31）mg／m3，（1．88±0．6）mg／m3。相对于蛋鸡，育成鸡更易受到外界活动的影响，因其活动能力强，新陈代谢快，产生的粪便湿度大，更易释放氨气。蛋鸡舍和育成鸡舍中温度分别为（27．1±1．8）℃和（27．5±0．5）℃，略高于最适温度13～23℃。相对湿度分别为（66．1±5．5）％和（62．1±3．8）％，达到最适湿度范围60％～70％。蛋鸡舍内温度和相对湿度与NH3浓度的Pearson系数分别为0．081和0．031，可见温湿度的变化对鸡舍内NH3浓度未造成明显影响：而通风条件的改变会引起NH3浓度的明显变化。This paper was to monitori natural ventilation,humidity,temperature,ammonia concentration in two different growth cycles house and explore ammonia concentration accumulation characteristics at different growth stages. Daily mean ammonia concentrations in laying house and breeding hen house were （1.94±0.31）mg/m3, （1.88±0.6）mg/m3,respectively. Compared to laying hen,breeding hen is more vulnerable to the impact of external events. It has more activities ability, faster metabolism,resuhing in fecal humidity,easier to release ammonia. Temperatures in laying house and breeding house were （27.1±1.8） ℃ and （27.5±0.5） ℃,slightly higher than the optimum temperature of 13-23 ℃ Relative humidity was （66.1±5.5） % and （62.1±3.8）%,achieve the optimum humidity range 60%-70%. Pearson coefficients of temperature, humidity and ammonia concentration in laying house were 0.081 and 0.031,respectively. The results showed that changes in temperature and humidity wouldn＇t cause significant impact on ammonia concentration inside the house. The ventilation conditions change could significantly cause change of ammonia concentration.
