These are a couple of short-horned cattle, not shorthorn cattle which is an established breed of cattle. These two have had the ends of their horns removed. Unlike dehorning, when the entire horn is removed, removing only the tip is not supposed to be painful because that part of the horn is just keratin.

This kind of procedure is probably to reduce the risk to people handling the cattle, but I have seen these cattle in the company of others with a full set of horns, so I guess it’s a case of let the handlers beware.
