linPRO®-BR as a source of Omega 3 and Bypass Protein for dairy cows
As is well known, Omega-3 fatty acids are a very important element in modern 
human nutrition circles. In times past, however, flaxseed (as reported in older books) was widely used in the diets of all dairy animals, being the main “oil meal”. Of course, it was almost always the by-product of oil extraction from flaxseed, but today the interest is more focused on the whole seeds which contain the full complement of oil (over 40%) of which about 50% is the important Omega-3 fatty acid called alpha-linolenic acid (ALA).
Interest in feeding cows Omega-3 enriched diets stems from several reports 
indicating improved overall reproductive performance, animal health and reduced methane. Omega-3 fatty acids are linked to improved immunity and given the sensitivity of today’s cows to even subclinical forms of several diseases, any help is welcome among dairy producers. In order to feed whole flaxseed, it is important that it is thermally processed; one such treatment is extrusion. It appears that feeding extruded flaxseed may have more benefits in terms of being a good source of bypass protein, thus competing with bypass soy.
