Over the last 5 years a number of methods have been developed and adapted to measure and quantify methane emission from individual animals. Their approaches show similarities and yet also differences. In general they focus on being noninvasive measuring in the cow everyday environment. In order to make genetic selection for methane emission it will be necessary to make large scale measurements in commercial farms. International collaboration, comparison and validation are essential to make progress in this area. It will be necessary to have strategic collection and exchange of data. More work is needed on how to get small scale phenotypes in to large scale genomic selection
