摘要
为探究彩钢结构卷帘羊舍能否适应夏季农区肉羊舍饲生产,对彩钢结构卷帘羊舍与彩钢结构封闭式羊舍夏季环境参数进行测定与比较分析。结果表明,彩钢结构卷帘羊舍舍内日均温度29.4℃,比彩钢结构封闭式羊舍日均温度低0.1℃,低于同期舍外环境温度0.7℃。卷帘羊舍内湿度(日均湿度81.2%)高于封闭式羊舍(日均湿度79.7%),更接近于舍外环境。彩钢结构卷帘羊舍内CO2和NH3日均含量均低于彩钢结构封闭式羊舍,两种羊舍均没有检测到H2S含量,羊的心率和呼吸频率均高于正常水平,日增重低于正常水平。研究结果提示,彩钢结构卷帘羊舍防暑散热效果好于封闭式羊舍。夏季通风换气效果好于封闭式羊舍,空气质量优于封闭式羊舍;夏季高温高湿对肉羊正常生产有一定影响,应采取适当防暑降温措施,以保障肉羊正常生产。
To investigate whether the rolling sheep shed of colored steel structure can fit mutton sheep production of drylot feeding on summer in farming areas,the environmental parameters of the rolling sheep shed of colored steel structure and the closed sheep shed of colored steel structure were measured and compared in summer.The results reveal the daily average temperature in the rolling shed was 29.4℃,0.1℃lower than the closed shed and 0.7℃ lower than outdoor temperature.It suggests the heat radiating effect of rolling shed is better than closed shed.However,the daily average humidity of rolling shed(81.2%)is higher than closed shed(79.7%)and closer to the outdoor humidity.The results of inner air quality measurement reveal the daily average content of CO2 and NH 3 are both lower in the rolling shed than closed shed;and no H 2S is detected in two sheds,showing that the air quality is better in the rolling shed than closed shed.Physiological indexes of sheep in the two types of sheep shed are determined,revealing the heart rate and respiratory rate both higher than the normal levels and average daily gain lower than the normal levels,which suggests the high temperature and high humidity in summer have a certain influence on the regular production of mutton sheep.Appropriate measures should be taken to prevent heatstroke so that the regular production can be guaranteed.
