Linseed meal is the byproduct of extracting the oil from flaxseed. It is used as a protein supplement and contains somewhat less TDN than soybean meal. A good source of selenium, it averages 1.0 ppm.

Linseed meal is very palatable. It may be included in the grain mix at a level of up to 25 percent of feed to milking herds at a rate of up to 9 pounds (4kg) per head per day.
