In an often fierce contest, it is decided which will be the queen cow leading the herd up to the Alpine meadows. The fights do not take place in organized fashion; each cow simply chooses her opponent on the spur of the moment. She suddenly stops grazing, lowers her head, snorts, and paws the ground with her hooves. If a cow of similar strength accepts the challenge, she wastes no time in informing her opponent in the same manner. Prudently, they approach each other. The fight begins: heads clash and horns lock, each cow trying to get a good hold. Then they stand firmly and push with all their strength, the stronger one forcing the weaker to retreat. After the contest, which may continue for several minutes, the loser turns around and runs away, followed by the winner, who encourages the loser to remember "who's boss" by adding a few more blows with her horns.

In addition to these spontaneous clashes, there are also organized fights to determine a regional and cantonal queen.
