Unfortunately, Israel perfected milk yield a few decades ago; at the time, Israel was something like 10 times the world average, now it’s less than five but mostly because other big producers like Denmark adopted Israeli knowledge, and the world average went up.

It does not involve hormones, but it does involve afaik a very specific feeding regime, both times and content - and the content has no grass.

The resulting milk, as you would expect, is similar to making love in a canoe.

Americans, on the other hand, perfects cheap meat yield. That involves feeding corn to cows, not grass.

A Canadian guy I met once, who grew up on a farm, said their cows were grass fed but a few weeks before slaughter, they would switch the feed to corn, because that way the meat tastes less grassy - making it excellent quality (because grass) and excellent flavor (because no grass). Wouldn’t know myself being vegetarian for a few decades now.
