Compare this method of milk production with the same twitter feed last week (?)where the calf is kept with the cow during milking.

Removing the calf and bottle feeding is psychologically damaging to the cow and calf; done so in order to maintain yield. https://twitter.com/FarmersOfTheUK/status/1301039073977565191

Industrial milk production (which is what it is) is not to everyone's taste. I buy my milk like 99.9% of the UK via those methods. And the standards in many; although not all dairy farms, are very high. Been there, done that, got the T shirt.

However the trade off is big.

Dairy genetic fiddling, abnormally high yields (a lot more than what she would produce naturally - sometimes by over a factor of 20); the constant stomach ache from a high protein/ limited grass range diet with methane emissions; mastitis...the list goes on.
