It is by no small amount the yield from a milk cow have gone up in the past 100 years or even just half of that
The oldest cattle race here, that are still existing are dating back to the 17 - 1800, but of course not cattle you will find in either a dairy or meat production.
The breed was also modified with cross breading with dutch black & white cattle, but a estimated 100 cows are still here today, these are called "The Jutland cattle"

First publication on the Danish cattle breeds was published as late as 1881.
So forget about fancy Japanese beef, we got something much more exclusive going on here.
Yes sadly my country got a dog law some years ago banning some breeds, in response to gangster types having large dogs they did not control or was even fighting ( also illegal here )
So again a law that hit pretty much all but the intended targets, they should have made a law saying criminals can not have dogs,,,,, Period.
Granted some dog breeds need more work, though if you look at bite events here,,,,,, it have never been the big dogs that are on the top of the list, O no it is the little dogs, with no training or care by the owners that is at the head of that statistics.
Very rare is the root of the problem the dog itself.
