most cows mostly eat grass for most of their lives. whole corn is fed as a treat to entice them to eat the rest of the silage it's sprinkled on (in my experience).
No. Most cows do not because most cows are not free range.
instead of platitudes, maybe you could provide some facts about cattle diets. maybe a link from the USDA or FAO.
You just shared an infographic which showed that animal feed accounts for 76% of global soy production vs only 20% for direct human food. The point we were discussing was that eating meat is a less efficient use of land which appears to be supported by what you shared.
Judging by the other comments and profile, it's clear that you're not trying to have a discussion in good faith and may be a troll. I'm not going to engage further.
this is poisoning the well and name-calling. what i said is true, whether you want to engage with it or not.
that graphic shows that the feed that is given to animals is almost entirely the industrial waste from oil production. it's called "soy meal" or "soy cake"
