- Enteric methane (CH4) emissions were measured from six lactating dairy cows using the sulfur hexafluoride tracer technique. Three diets with different proportions of highly digestible grass silage/concentrates were fed: 500/500, 700/300, or 900/100 g /kg dry matter (DM). The average daily CH4 emissions were 282, 300, and 321 g /animal, respectively and the methane conversion factor (Ym) from gross energy (GE) ranged from 0.051 to 0.056. However, the statistical power of the study was weak and the differences between diets were not significant (P=0.149 and P=0.293, respectively). A linear regression analysis showed a trend (p=0.08) toward higher enteric CH4 emissions with higher proportion of high quality grass silage in the diet. A definite conclusion is not possible and further studies are needed as a base for concrete advice on how to mitigate enteric CH4 emissions from high yielding dairy cows in Scandinavia
