What is a cow?

A cow is a female bovine that has given birth to at least one calf. Cows are the “mothers” of the herd. They are kept for breeding and, in dairy herds, for milk. Only cows produce milk, because producing milk follows giving birth.

In everyday speech, “cow” often stands for any cattle, as in “there are cows in the field.” That casual use is fine in conversation, but “cattle” is the proper general word for the whole group.

What is a steer?

A steer is a male bovine that has been castrated, usually when young. Because it cannot breed, a steer is calmer and easier to manage than a bull. Steers are mostly raised for beef.

A steer will never have calves and never produces milk. You can tell it from a bull because a bull has not been castrated. A steer also tends to be less heavily muscled in the shoulders and neck.

Cow vs steer: what is the real difference?

The real difference is sex and reproductive status. A cow is female and can have calves. A steer is male and has been castrated, so it cannot sire any.

  • Breeding: A cow has had a calf. A steer cannot breed.
  • Milk: Cows give milk after calving. Steers never do.
  • Main purpose: Cows are kept for calves and milk. Steers are mostly raised for beef.
