Flax to reduce the amount of methane emitted by ruminants



Methane emitted by ruminants contributes significantly to global warming. The researchers therefore focus on this problem and try to find solutions for them: the integration of flax in the diet of ruminants is one of them.

If the amount of methane released into the atmosphere is much less than the amount of CO2, the gas emitted by ruminants is nonetheless extremely harmful to the environment since it is 23 times more on global warming that CO2.

In France, methane or CH4, is 5% of all greenhouse gases and to reduce this rate, it would seem that the integration of flax in the diet of ruminants is particularly effective.

If we now capture the CH4 content in manure, most of the methane emitted by ruminants east during digestion, and that is where the use of flax, rich in fatty acids, occurs.

Researchers at INRA (Institut National de la Recherche Agronomique) incorporated a quantity of seeds or flax oil can be up to 6% of the rations of ruminants, and found that methane emissions have declined by 27 to 37% without their digestion is still disrupted.

This experiment is completed, it must be done on a larger number of animals and the effects of flax long term are not yet known.
