South Dakota Beef

You don't have to wonder where your beef comes from. You have a choice. EcoSun Prairie Farms is now offering grass-raised beef for sale. Seventy-five Black Angus x Hereford cross yearling heifers have been grazing since mid-May (175 days) on the restored grasslands of the Prairie Farm south of Brookings, in eastern South Dakota. The cattle grew up on the restored 20,000 acre Mortenson Ranch west of the Missouri River near Eagle Butte, South Dakota. The Mortenson family was awarded the prestigious Aldo Leopold Conservation Award for 2011, so you know these cattle have had great care and great grass. We've picked out the best heifers to sell.

Beef from grass pasture or feedlot?


Evidence is mounting that the healthiest meat to eat comes from free-range animals raised on grass pastures (Mother Earth News). Not only is the meat healthier, but the animals are too. Meat from animals "finished" on grass for the six weeks before slaughter contains significantly more omega-3, poly-unsaturated fatty acids than meat from grain (British Journal of Nutrition 2011). Eating as little as three portions of grass-raised meat per week (18 ounces cooked) can increase the blood levels of these good, protective fats as much as some fish oils. Pasturing longer than 6 weeks may further raise dietary omega-3 blood levels. In short, grass pasturing meats are leaner and contain proportionally more of many important nutrients that relate to good health.
