摘要

集约化畜舍系统可以在减少氨(NH3)和温室气体(GHG)排放方面发挥相关作用。气体浓度监测是增加对大气中气体释放及其减少的认识的第一步。在文献中,很少有研究调查了地中海背景下的测量技术和采样策略,其中奶牛场的特点是大开口。调查的目的包括研究参数的设置、每次测量的重复次数、采样点的位置以及评估低成本气体浓度监测仪器的使用情况。利用红外光声光谱仪和基于电化学和红外传感器的低成本便携式仪器,在温暖时期在开放式谷仓中获取了NH3、甲烷(CH4)和二氧化碳(CO2)的浓度。应用统计分析评估数据变异性。提供了具体资料,说明如何收集数据和获得可靠的测量结果,重点是利用这两种不同的装置获取和监测谷仓环境中的气体浓度。发现监测优化受到测量技术、采样策略(即采样频率、采样地点的数量和位置以及仪器的设置)和监测目的(即气体测量、排放估计、缓解策略评估)的影响。

Gas concentration monitoring techniques by using an infrared photo-acoustic multi-gas analyser and low-cost devices in an open dairy barn.

Intensive livestock housing systems can play a relevant role in the reduction of ammonia (NH3) and greenhouse gases (GHG) emissions. Gas concentrations monitoring represents the first step to increase knowledge on the release of gases in the atmosphere and their reduction. In the literature few research studies have investigated the measurement techniques and sampling strategies in Mediterranean context where dairy barns are characterized by wide opening. The objectives of the investigation involve the study of the parameters' setting, number of repetitions for each measurement, position of the sampling points as well as assessing the use of low-cost instrument for gas concentration monitoring. Concentrations of NH3, methane (CH4) and carbon dioxide (CO2) were acquired in an open barn during warm periods by the use of an infrared photoacoustic spectroscope and low-cost portable instruments based on electrochemical and infrared sensors. Statistical analyses were applied to assess data variability. Specific information was provided on how to collect data and obtain reliable measurements by focusing on the acquisition and monitoring of gas concentrations in the barn environment by the use of the two different kinds of devices. The monitoring optimization was found to be affected by the measurement techniques, the sampling strategy (i.e., sampling frequency, number and position of sampling locations, and set-up of the instrument) and monitoring purposes (i.e., measurement of gas, emission estimation, assessment of mitigation strategies).

期刊介绍: Journal of Animal Science and Technology (J. Anim. Sci. Technol. or JAST) is a peer-reviewed, open access journal publishing original research, review articles and notes in all fields of animal science. Topics covered by the journal include: genetics and breeding, physiology, nutrition of monogastric animals, nutrition of ruminants, animal products (milk, meat, eggs and their by-products) and their processing, grasslands and roughages, livestock environment, animal biotechnology, animal behavior and welfare. Articles generally report research involving beef cattle, dairy cattle, pigs, companion animals, goats, horses, and sheep. However, studies involving other farm animals, aquatic and wildlife species, and laboratory animal species that address fundamental questions related to livestock and companion animal biology will also be considered for publication. The Journal of Animal Science and Technology (J. Anim. Technol. or JAST) has been the official journal of The Korean Society of Animal Science and Technology (KSAST) since 2000, formerly known as The Korean Journal of Animal Sciences (launched in 1956).
