Calves.
A normal non-farmed cow only starts to make milk when they give birth to a calf and they slowly ramp down production as the calf weans. Farmed cows get milked every day so they continue producing milk, they never “wean”. You can’t just go cold turkey…if you sloooowly ramp down milk production you can get the cow back to normal non-milk producing state.
