相对湿度对急性偏热处理肉鸡行为、生理、糖脂代谢的影响

Effects of Relative Humidity on Behavior,Physiology and Glucose and Lipid Metabolism of Broiler at Acute Moderate Temperature

研究旨在探讨相对湿度对急性偏热23℃处理肉鸡的行为、生理、糖脂代谢的影响。肉鸡在人工气候实验舱内饲养,采用目标取样法,统计存储视频中的目标鸡各种活动行为、休息行为发生的次数;借助红外热成像仪和FLIR TOOIS分析皮温;检测血清葡萄糖、总胆固醇、甘油三酯含量指标。结果显示:急性偏热环境(23℃)中不同湿度(35%、60%、85%)处理肉鸡的行为、生理、糖脂代谢指标呈现不同的变化。表明急性偏热23℃时高湿和低湿不同程度上影响肉鸡体热调节。

The aim of this study was to reveal the influence of relative humidity on behavior, physiology and glucolipid metabolism of broilers at an acute moderate temperature of 23℃. Broilers were raised in the experimental module under the artificial climate. The target sampling method was adopted to statistically record the frequency of moving and resting of target broilers. The skin temperature was analyzed using the infrared thermal imager and FLIR TOOLS. The serum glucose（GLU）, total cholesterol（TC） and triglyceride（TG） were detected. The results showed that broilers′ behavioral, physiological and glucolipid indexes at different humilities（35%, 60% and 80%） and 23℃ had different changes. It′s suggested that at the acute moderate thermal temperature of 23℃, the high-humidity（85%） and low-humidity（35%） processing could affect the regulation of body heat in broilers.
