【摘要】 本研究对接坝地区3种不同类型的犊牛舍内不同季节的环境参数进行监测，分析不同类型犊牛舍内环境参数季节性变化的特征，并统计分析不同牛舍、不同季节的犊牛平均日增重及其发病率。结果发现：（1）春季舍内CO₂浓度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01），保温犊牛舍显著高于阳光犊牛舍（P<0.05）；春季舍内NH₃浓度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01）。（2）夏季舍内CO₂和NH₃浓度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01）；夏季舍内温度，传统犊牛舍显著高于保温犊牛舍（P<0.05）；夏季牛舍内噪音，保温犊牛舍极显著高于阳光犊牛舍、传统犊牛舍（P<0.01）；夏季舍内风速，传统犊牛舍显著高于阳光犊牛舍（P<0.05）。（3）秋季舍内CO₂和NH₃浓度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01）；秋季舍内湿度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01），保温犊牛舍极显著高于阳光犊牛舍（P<0.01）；秋季舍内噪音，阳光犊牛舍和传统犊牛舍显著高于保温犊牛舍（P<0.05）；秋季犊牛平均日增重，保温犊牛舍显著高于传统犊牛舍（P<0.05）。（4）冬季舍内的CO₂浓度，传统犊牛舍极显著高于保温犊牛舍、阳光犊牛舍（P<0.01）；冬季舍内的NH₃浓度和温度，保温犊牛舍、阳光犊牛舍极显著高于传统犊牛舍（P<0.01）；冬季舍内湿度，传统犊牛舍、阳光犊牛舍显著高于保温犊牛舍（P<0.05），冬季舍内犊牛平均日增重，保温犊牛舍显著高于传统犊牛舍（P<0.05）。（5）四个季节的犊牛发病率均是传统犊牛舍最高，夏、秋、冬的犊牛发病率保温犊牛舍最低。基于试验结果，使用保温犊牛舍更有利于犊牛舍内环境参数的控制，更有利于提高犊牛生产性能、降低发病率。更多还原

【Abstract】 This paper monitors the environmental parameters of three different types of calf sheds in Dam-connected area across different seasons. It analyzes the seasonal variation characteristics of environmental parameters in different types of calf sheds. Through statistical analysis of the average daily weight gain of calves in different seasons and their health and growth conditions, the following findings were obtained.（1） In spring, the CO₂ concentration in traditional calf sheds was extremely significantly higher than that in insulated and solar calf sheds（P<0.01）, and the insulated calf shed was significantly higher than the solar calf shed（P<0.05）. The NH3 concentration in traditional calf sheds was extremely significantly higher than that in insulated and solar calf sheds（P<0.01）.（2） In summer, the CO₂ and NH₃ concentrations in traditional calf sheds were extremely significantly higher than those in insulated and solar calf sheds（P<0.01）. The temperature in traditional calf sheds was significantly higher than that in insulated calf sheds（P<0.05）. The noise level in insulated calf sheds was extremely significantly higher than that in solar and traditional calf sheds（P<0.01）. The wind speed in traditional calf sheds was significantly higher than that in solar calf sheds（P<0.05）.（3） In autumn, the CO₂ and NH₃ concentrations in traditional calf sheds were extremely significantly higher than those in insulated and solar calf sheds（P<0.01）. The humidity in traditional calf sheds was extremely significantly higher than that in insulated and solar calf sheds（P<0.01）, and the insulated calf shed was extremely significantly higher than the solar calf shed（P<0.01）. The noise level in solar calf sheds was significantly higher than that in insulated and traditional calf sheds（P<0.05）. The average daily weight gain of calves in insulated calf sheds was significantly higher than that in traditional calf sheds（P<0.05）. In winter, the CO₂ concentration in traditional calf sheds was extremely significantly higher than that in insulated and solar calf sheds（P<0.01）. The NH₃ concentration and temperature in insulated and solar calf sheds were extremely significantly higher than those in traditional calf sheds（P<0.01）. The humidity in traditional and solar calf sheds was significantly higher than that in insulated calf sheds（P<0.05）. The average daily weight gain of calves in insulated calf sheds was significantly higher than that in traditional calf sheds（P<0.05）. Based on the experimental results, the use of insulated calf sheds is more conducive to the control of environmental parameters in calf sheds, and more beneficial to improving calf production performance and reducing the incidence of diseases.更多还原
