I think far fewer people would be vegetarian if any aspect of modern farming looks even remotely the way you describe below. At most a tiny fraction of the cows in milk or meat production (and basically NONE of the pigs or chicken) ever see an open pasture in their lives. Cows are impregnated and kept in small fenced areas,l all their lives. Their babies are removed most often right after birth, sometimes a few days later. The calves are separated and kept with other calves, fed a small share of the milk produced by their mothers (or even just from the tank containing all cows' milk. The males are butchered as babies and the females raised for milk production and share the fate of their mothers - dozens of babies, taken away each time right after birth. All of them are fed various kinds of medicine (steroids, antibiotics, etc) to make sure they grow fast and survive, irrespective of whether they suffer. For slaughter they are usually first stuffed in wagons or trucks and carted hours to whatever abattoir paid the best price. There they are in a long queue where they hear and smell and later see the animals in front of them being killed. The 'shock' is often hit or miss, meaning many are alive when they get the bolt into their skull, others even survive that for a bit. All that just so that you get a cheap burger. Dozens of the quality labels are just lies: e.g. Grass fed means they got grass, not that they were ever outside. Most animals never see the sky in their lives. I appreciate that it could be much more humane, but to ignore that the above is the reality today is just willful denial. Advertisements show you beautiful alps or Argentinian meadows, but these are not the reality in which your animal actually lived.
