> There are some large dairy cooperatives in the US

They don't tend to own processing infra, though that is slowly starting to change. And some of them line "Land o Lakes" are cooperatives in name only, and are very abusive to small farmers, because they can only process at 1k+ head sizes.

> It looks like Michigan's milk producer cooperative is selling in some partnership with India’s Gujarat Co-operative Milk Marketing Federation Limited (GCMMF)

Yep! Because India can't export Indian milk to the US without tariffs, and American cows are fed meat, so Amul decided to corner the vegetarian milk market by making the cooperative deal with MI.

Blume Ventures had a good write-up on this I need to find.
