What do you feed them? Take a look at the quality of the pasture. Is it well maintained? Does it appear healthy? "See how they're tending to the animals when they don't have a fresh grazing opportunity," suggests Jo Robinson, editor of eatwild.com. When grazing is not an option, animals should be eating "good-looking grass hay or grass silage, which is fermented grass," she says. Debra English of Jack Straw Farm goes a step further, urging consumers to ask how beef is "finished." She explains that some cows eat grass for most of their lives but grain at the end ("grain-finished"), which negates some of the benefits of grass feeding.
