The idea that herbivores should eat grass shouldn?t seem radical, but due to a combination of subsidies and surpluses the grain feed lot?where meat animals are fed corn and soybeans?has become the norm over the last generation. In 1984 a Mississippi farmer named Alan Nation visited New Zealand where he saw farmers raising sheep and cattle in pastures. Nation realized that grazing animals on pasture had benefits for animal, humans, and the environment; he returned home to found a magazine called The Stockman Grass Farmer, which became the bible for a new movement in management-intensive grazing, also known as rotational grazing..Management-intensive grazing is not just about leaving animals in the field all day; it focuses on the nurturing and care of productive pastures. Thus, grazers refer to themselves as ?grass farmers,? with animals being a by-product of good stewardship of the grass. If the feed lot is an animal city, then management-intensive grazing represents a new urbanism, where animals graze at high stocking rates simulating the type of grazing and land use naturally practiced by large herds of migratory herbivores. Advocates of pasture-raised livestock promote grass-fed meats as being higher in omega-3 fatty acids and better for the environment..
