yes, industrial feedlot farming and they also on top of that feed them almost exclusively on GMO grains.
it's not even only just about how unnatural and unpleasant it is for the animals, not eating grass changes their meat in ways that makes it less good for you, or even allergenic. i can't eat the eggs produced on this island because they are mostly fed on GMO corn and it gives me a severe allergic reaction after a few days of 4 eggs a day.
the thing is, this style of farming is NOT any more efficient. it just funnels money to the big agricultural biotech companies. feed your sheep and cattle on grass and they are cut out of the deal.
none of it is necessary, regenerative herding is better for the land as well as producing a better product and less unnatural and cruel to the animals.
one of the most insulting things about the whole vegan meme is the idea that all farmers are cruel psychopaths. no, actually, they are not, but the big scale ones kinda are, and they are really just captured serfs serving the big agra oligarchy, and those are the customers, not us, we are parrt of the product. as in, making us sick is part of the plan.
