Reduce emissions by 20% with the Methane Index
Breeding cows that permanently emit less methane is now a reality thanks to the Nordic Methane Index.
Methane emissions from cows are one of the most pressing challenges for dairy farming’s green transition.
Scientific studies have shown that 20% of a cow's methane production can be attributed to her genetics. This means that by selecting and breeding cows with favourable genetic traits, cattle’s methane emissions can be reduced by 20%.
Starting from the May 2025 proof run, methane breeding values is calculated for all VikingHolstein bulls born after 2008. The methane indices for VikingJersey and VikingRed animals will be released in 2026.
