O.K. I guess, if you don’t mind your milk, cream, cottage cheese, yogurt, ice cream, etc. all tasting like oregano. Any strong flavor that a cow eats passes through into the milk. In the spring wild garlic in the pastures is a problem because the cows love to eat it, but the garlic stinks up the milk. Sometimes if the milk from a particular farm is really strong, the bottling plant will reject it, and it goes down the drain.
Nowadays with large farms, and cows kept confined, garlic is no longer as big a problem. But if you FEED them oregano, you bring it on yourself. Total insanity, IMHO, since global warming is a lie and a farce to begin with.
P.S. That very inquisitive-looking cow in the photo below your reply looks very much like one of the Chick-fil-A photo models in their advertising.
One of my cousins likes to do his deer hunting in an area with lots of wild onions. He gets his venison pre-seasoned.
