So, what is grass-fed milk?

“Grass-milk” comes from cows fed a nearly 100 percent forage-based diet. During the grazing season dairy cows consume nearly all their dry matter  from pasture. The cows may consume certain mineral and energy supplements, such as molasses, at low levels. During the non-grazing season, grass-milk cows must consume all forage-based feeds, these may include dried or fermented forages (alfalfa, clovers, grass). Cows may also eat cereal crops harvested prior to the boot stage, such as oats and barley.

Annual and perennial forage crops are managed throughout the year to provide for both grazing and stored winter feed. Many grass-milk farmers harvest feedstuffs that are preserved to be fed as baleage. An increase in grass-based diets for cows requires careful management of pasture composition and forage production, soil fertility, and animal health.

Effect of grass-milk on human diets

Omega-6 and omega-3 fatty acids are essential human nutrients, yet consuming too much omega-6 and too little omega-3 can increase the risk of cardiovascular disease, obesity and diabetes. Research has shown that consuming organic dairy products lowers dietary intakes of omega-6, while increasing intake of omega-3 and conjugated linoleic acid (CLA), a heart-healthy fatty acid.

A recent national study found that cows fed a diet of totally organic grass and legumes produced milk with elevated levels of omega-3 and CLA, which provides a markedly healthier balance of fatty acids. The improved fatty acid profile in grass-fed organic milk and dairy products brings the omega-6/omega-3 ratio to nearly 1 to 1, compared to 5.7 to 1 in conventional whole milk.

Consumer benefits of switching to grass-milk

We modeled daily fatty acid intakes for a typical 30-year old woman consuming a typical diet in the United States to assess the impact of switching to grass-milk dairy products. Shifting from conventional to grass-milk dairy products may have a positive impact on total omega-3 and CLA intake.

• Three servings of grass-milk provide about 300 milligrams of CLA, which is 75 percent of the target intake for adult men and 100 percent of target levels for adult women.
• For omega-3s, three servings of grass-milk would provide about 22 percent of daily needs for adult men and 32 percent   for adult women. Conventional dairy products would supply less than half of these amounts.
• Three daily servings of grass-milk would supply up to 58 percent  of total daily omega-3 intake, making dairy by far the primary source of omega-3 fatty acids across all food groups.

Most of the omega-6 in the American diet today comes from fried foods, vegetable oils and processed foods, with little coming from dairy. For people striving to lower their risk of cardiovascular and other metabolic diseases, for pregnant women, and for infants and children, the greater omega-3 intake from grass-milk may help improve human health.

A2 Milk

We have tested our herd and we have 98% A2 cows.

There is research out there citing a/2 a/2 milk might prevent diabetes and autism along with other illnesses.
This made us decide to transfer our herd , aiming  for all cows to produce milk  with a full string of proteins like it was hundreds of years ago. Thru hair samples send to a lab ,DNA determines if a cow is a truthful A/2-A/2 cow.

You do your research and make a judgement, there is no harm in trying.
