温室气体（GHG）的产生作为气候变化的原因之一，被认为是当今社会面临的最大问题之一。畜牧业是人为温室气体排放的主要来源之一。此外，大量的氨（NH3），导致土壤硝化和酸化，由牲畜产生。因此，目前正在考虑其他动物蛋白质来源，如可食用昆虫。进行了一项实验，以量化生产的二氧化碳（CO2）和平均日增重（ADG）作为饲料转化效率的措施，并量化的温室气体甲烷（CH4）和一氧化二氮（N2O）以及NH3的生产由五种昆虫，其中前三种被认为是可食用的：黄粉虫，Acheta acuticus，飞蝗，Pachnoda marginata，和Blaptica dubia。物种之间的差异很大，关于他们的二氧化碳和温室气体的生产。本研究中的昆虫具有更高的相对生长率，并且排放的温室气体量与文献中描述的猪相当或更低，并且比牛的温室气体量低得多。每公斤代谢体重和每公斤增重的CO2产生量也是如此。此外，昆虫产生的NH3也低于传统牲畜。因此，这项研究表明，昆虫可以作为一个更环保的替代生产动物蛋白的温室气体和氨排放量。本研究的结果可作为基本信息，通过生命周期分析比较昆虫与传统牲畜的生产。
Greenhouse gas (GHG) production, as a cause of climate change, is considered as one of the biggest problems society is currently facing. The livestock sector is one of the large contributors of anthropogenic GHG emissions. Also, large amounts of ammonia (NH3), leading to soil nitrification and acidification, are produced by livestock. Therefore other sources of animal protein, like edible insects, are currently being considered. An experiment was conducted to quantify production of carbon dioxide (CO2) and average daily gain (ADG) as a measure of feed conversion efficiency, and to quantify the production of the greenhouse gases methane (CH4) and nitrous oxide (N2O) as well as NH3 by five insect species of which the first three are considered edible: Tenebrio molitor, Acheta domesticus, Locusta migratoria, Pachnoda marginata, and Blaptica dubia. Large differences were found among the species regarding their production of CO2 and GHGs. The insects in this study had a higher relative growth rate and emitted comparable or lower amounts of GHG than described in literature for pigs and much lower amounts of GHG than cattle. The same was true for CO2 production per kg of metabolic weight and per kg of mass gain. Furthermore, also the production of NH3 by insects was lower than for conventional livestock. This study therefore indicates that insects could serve as a more environmentally friendly alternative for the production of animal protein with respect to GHG and NH3 emissions. The results of this study can be used as basic information to compare the production of insects with conventional livestock by means of a life cycle analysis.
