Quebec dairy cows in flax experiment
Thirty of Quebec's dairy farms are participating in an experiment designed to reduce the gaseous emissions from their cows.
On a yearly basis, a cow can put out about as much in the way of greenhouse gases as a car, 99% of it emitted in burps. Adding ground flaxseed to the cows' food reduces the emissions by about 12-percent, according to previous studies in other countries.
The Journal de Montreal reports that for the Quebec experiment, flax will make up about 10-percent of the feed, The 100 tons of flax needed will be imported from France.
As a side effect, the addition of flax will boost the omega-three content of the milk the cows produce.
