There's a British farm that lets the cows roam freely and has a series of automated robot milkers set up.
The cows can just walk into the milk barn and line up however they want, and the robot will milk them.
They're not lined up tightly in a row to maximise cow per square foot, instead they have tonnes of room and there's no fencing or gating within that milk barn other than to keep the cows on the farms.
When the cows are done, they just walk out.
Now environmentalists will say that it is utter tyranny to milk a cow traditionally and only squeeze 25L to 35L out of the udder per cow per day, and this experimental farm proves them right.
Cows which merrily walk into the robot milkers are very comfortably producing 60L per day. The record is at 85L iirc, from a cow which cannot stop leaping giddily into that barn.
This proof however is in stark contradiction to the narrative of the environmentalists. A happy cow does indeed make more milk. Freeing them the environmentalist way might make the cows happier, which means they'll make way more milk.
This experimental way combines freedom with milkers. Happy days for all.
Oh yeah one more thing, the consistency and nutritional value of each litre of milk made on that experimental farm?
It's greater, denser, and the milk is healthier for it.
And it doesn't cost more space.
It's wonderful. To get the same amount of alternative product, you need multiple times the amount of land and you don't get that amount every day.
