Surprisingly, more than a third of all world’s methane emissions (around 900 billion tonnes/year) is generated by gut bacteria in farm animals such as cows, sheep and goats.
Scientists now say that feeding fish oil to flatulent cows can help fight climate change.
The new study suggests that including two per cent fish oil in the diet of cattle can significantly reduce the animals’ methane emissions.
Fish oil contains omega-3 fatty acids which have been shown to help the heart and circulatory systems of livestock as well as improve meat quality.
