Wild cow milking is a rodeo event seen at mainstream and ranch rodeos. A team-based competition, the goal is to catch and milk a "wild" cow (a semi-feral animal that is not used to being milked by people, usually of a beef cattle breed) in as short a time as possible. The competition dates back at least to the early 20th century, with competitions at the Cheyenne Frontier Days rodeo photographed as far back as 1924.
