what is the context for this photo please? (that is not a calf btw?)

It certainly does not look very nice, are you relating this to the "Ethically Raised in the Swiss Alps Cows" in the comment you replied to?

In truth, they just take the calves away from the mothers after a short while, ship them out to the abbatoir. There is no benefit to them being in the same enclosure with a spiky nose ring, it seems that this must have a different purpose than the one you mentioned.

I suggest reading/listening a little bit outside of the PETA propaganda bubble. For example, here's a good short discussion on the topic with a cattle farmer: https://www.youtube.com/watch?v=n4cHn6NX4wQ
