Steer
A male castrated young and raised mainly for beef, in North American and Australian usage.
Also: stot, beef steer
A steer is a castrated male raised for meat. The word is used mainly in North America and Australia, where steers make up much of the beef cattle sent to market at around eighteen months to two years old. Castration makes animals calmer, easier to keep in mixed groups and less likely to fight, and it changes how they lay down fat. In British usage a young castrated male kept for beef is more often called a bullock, and in Scotland a stot. A steer trained for work and grown to full size becomes an ox. Steer wrestling and steer roping are standard rodeo events.
