北京市气候变化对奶牛热冷应激的影响
气候变化对奶牛养殖的影响日益凸显,一些地区奶牛养殖的热应激或冷应激外部环境有所加剧。该文采用温湿度指数(temperature humidity index,THI)和风寒温度(wind chill temperature,WCT)2个指标,分析了北京地区1951-2012年逐日的THI和WCT的变化特征,重点分析了气候变化对奶牛养殖应激环境变化规律的影响。结果表明:近62a来北京地区温度提升了1.93℃,气候变暖特征明显快于全国,气候变化加剧了北京地区热应激温度环境,降低了冷应激温度环境,综合考虑相对湿度和风速等气象因素,气候变化对北京地区热应激综合环境影响小,对冷应激综合环境影响大。但值得...

| Summary: | 气候变化对奶牛养殖的影响日益凸显,一些地区奶牛养殖的热应激或冷应激外部环境有所加剧。该文采用温湿度指数(temperature humidity index,THI)和风寒温度(wind chill temperature,WCT)2个指标,分析了北京地区1951-2012年逐日的THI和WCT的变化特征,重点分析了气候变化对奶牛养殖应激环境变化规律的影响。结果表明:近62a来北京地区温度提升了1.93℃,气候变暖特征明显快于全国,气候变化加剧了北京地区热应激温度环境,降低了冷应激温度环境,综合考虑相对湿度和风速等气象因素,气候变化对北京地区热应激综合环境影响小,对冷应激综合环境影响大。但值得关注的是,2008年以来,北京地区热冷应激环境呈现"双升"态势,尤其冷应激环境明显增强,2012年冷应激天数为近10a来最高,对北京地区的奶产量产生了不利影响。研究结论对以开放或半开放式牛舍养殖为主的北京地区的牛舍改造和应激设施设备改善提供了科学决策依据。 |
