How do cows express their emotions?

So . . . I guess no moos is good moos.

Of course you can tell happy moos, just as you can tell angry moos.

Player #92723922, I have personally witnessed a mother cow crying tears when her calf was taken away. She was sad for sometime.

L, Last fall I was at a rural, truck stop type gas station. There was an entire herd of cows next door, very close in the dark, mooing loudly & constantly in great distress. I grew up on a dairy farm, have been near them all my life. I had never heard anything like this. It was heart-breaking. We asked about it & were told all their calves had been taken away that day.

L, how sad!!! There’s a strong bond between mother n baby even in the animal kingdom… I can’t imagine what the baby was going through!!

Shelley, I'm crying.

L, exactly what I was going to comment. I will never forget those terrible sad moos. Heartbreaking.

Shelley, answer, don't drink milk, it belongs. to the calves

L, wow 😲 I'm speechless.

I milked a Guernsey every morning and evening. She was a great cow! I cried like crazy when my parents sold her.

L, oh, come on!🤪

The same applies with other animals. Localization and body language reveal a lot. Same with humans.
