I'm human, but one of the ones who likes to study and learn. Cattle are ruminants, they eat grasses and forbs, and grains at the end of the season. 'Grain Fed' was sold to us as better tasting, better for us beef, turns out it's a horrible way to raise cattle for consumption, other than making money faster. We are eating muscle filled with inflammation, the antibiotics are needed to keep them from dying of the infection brewing in their rumens, where it's a race to feed the steer and get him to market weight before that infection kills him - it's nasty. The ratio of omegas is off because they should be eating the grasses that are full of Omega-3s, instead they're eating corn that's full of Omega-6s, that sends our cholesterol off - but someone is making money!! I guess that's the more important thing here, not good food production but profit margins. We've been sold a bill of goods, it's the root of so much of the health problems in this country (obesity, high cholesterol, diabetes - heck, diabetes is a lifestyle now!).
Brian, you and your brother had it right - Joel Salatin is working that system pretty well for himself down in Virginia.
