Cows eating grass has nothing to do with organic agriculture. This is nothing more than spin by the organics people because they got proven to be charletans recently.
That "to be considered organic" statement is just about a flat out lie (can't be definite as it depends under what certification). Organic milk has little to do with a cows access to grass, or the implied lack of said same in conventional ag. Organic is to do with the use of herbicides, pesticides and chemical fertilisers.Quote
Conventional dairy and cattle production has been shown to be superior to organic, both from a gross production, animal health and efficiency standpoint. There is no difference in the actual nutritional value of the meat or milk!!!
Addressing this specific finding: They were comparing cows who ate grass with those that don't. They were not comparing organic and conventional ag, that is subversion. Grass fed is superior. I haven't seen any data on cows fed on a silage/hay ration, which a large proportion of the industry does (especially in the colder areas of America where they have to shed the animals most of the year). At a guess I'd say it would be slightly inferior to grass fed due to the difference in feed quality compared with fresh grass.
