Bullfighting "steers"?
 

We have tickets for Las Ventas May 17th . which was advertised as a bullfight. Now when I look at the schedule it shows "steers" instead of bulls. What does this mean?
I really do not want to stir up another huge discussion of the morality of this. I just want to know if this is a real bullfight.
thanks

The bullfight on May 17th, during San Isidro, is a corrida de novillos, with the young bulls (under 4 years of age) of José Joaquín Moreno Silva of Córdoba. Fighting will be Paco Chaves, Miguel Hidalgo & Antonio Rosales.

Steers are castrated bulls. In younger cattle, it can also refer to young bulls, as Robert mentions. Unless required for breeding, bull calves are generally castrated when they are a few months old.

This is a corrida with young bulls (as robert correctly says) which are not (repeat, NOT) castrated, and it'll be the same as a corrida.

I didn't check their weights, but they could be very fast on their feet, which makes them very dangerous.
