18/06/2014
Main tasks
WG1
Work Group 1
…to compile :
a) an inventory and discuss possible factors associated with
variation in methane production
b) standardized definitions for methane measurements
c) combined and integrated data into novel genetic models

WG1
Inventory, next steps (according to tasks)
1) …discussing possible factors associated with variation in methane
production
2) …standardization between methane measurement methods????
 Collaborative work with WG 2 necessary!!!
Transfer into yields?
 Quality and relationship between direct measurements and indicators???
 Collaborative work with WG 3 necessary!!!
Relationship between CH4 concentration and CH4 yield ?
M. Chagunda, Animal 2013
 Relationship between rumen CH4 and whole-body CH4 ? (Range 3-12%!)
 Same issue with methane indicators (WG3)
 Persistency and Repeatability ?
