Do Wagyu cows get massaged?

I've heard some fascinating rumors about Wagyu cows being pampered with luxurious treatments like massages. Can you confirm if this is actually true? I'm intrigued to know if these cows really do receive such meticulous care and if there's any scientific basis behind it. It seems like an unusual yet intriguing practice, and I'd love to hear more about the reasons behind it, if indeed it's a reality.
