Special Issue Information
Dear colleagues,
Current environmental concerns require each sector to make efforts to mitigate its greenhouse gases (GHGs) emissions. In this context, more and more research is dedicated to acquiring such values more easily, with the purpose of elaborating strategies to reduce them. The agricultural sector and more especially livestock production are also concerned. As reference techniques to measure GHGs from animals are expensive and time consuming, alternative techniques are developed. The values collected help to define strategies to reduce GHGs emissions.
The aim of this Special Issue of the open-access journal Animals will be dedicated to advances of techniques to measure or to estimate indirectly (by proxies) GHGs emissions from livestock as well as their application to reduce GHGs emissions in practice (nutrition, genetic, etc.).
Original research, systematic reviews, meta-analyses, and model studies related to the theme of are welcome. Example topics include, but are not limited to:
New techniques to measure GHGs emissions from livestock to acquire them more easily
- Development of proxies for indirect estimation of GHGs from livestock at large scale
- Potential to merge reference datasets acquired with different reference methods
- Studies about evolution of GHGs at animal, herd or regional scale
- Integration of measured or estimated values in LCA
- Strategies to reduce GHGs emissions from livestock
We are looking forward to your submissions!

Title: Detection of methane eructation peaks in dairy cows using signal processing
Abstract: Mobile gas analysers provide a potential method for measuring individual animal enteric methane emissions by detecting eructation peaks. The objective of this study was to investigate using signal processing to detect eructations during milking and compare measurements from three gas analysers that differ in volume of air sampled and speed of processing sampled air. A total of 5,512 methane spot measurements were obtained from 65 cows over a 3 week period. Methane in air (parts per million) was measured continuously every second from the feed bin of the milking station using a Guardian SP, Guardian NG both sampling at 0.75 L/min and IRMAX at 0.75 L/min in week 1, 375 L/min in week 2 and 750 L/min in week 3. Peak analysis software was used to extract the maximum methane amplitude (in parts per million) during each milking. A linear mixed model was including the fixed effects of analyser × week of study, lactation number, days since calving and the random effect of individual cow was used for the analysis. The study found that at the same air sampling volume there was no difference in methane concentration between analysers. Increasing volume of air sampled by the IRMAX resulted in a higher concentration measured by the IRMAX and a lower concentration measured by the SP (P<0.001). The Guardian SP provided the most repeatable measurement and detect more variation among cows.
