What is the difference between a steer and a bull and an ox?

Answer 1

An ox is a castrated male bovine (or even, on occasion, a cow or heifer) that has been trained and is used for draft work.

A steer, on the other hand, is simply a castrated male bovine, typically one that has been castrated prior to reaching sexual puberty, that is grown for meat, not for draft work.

Answer 2

A calf is a baby bovine of any gender, while a heifer is a female bovine. Heifers can be specified as heifer calves, yearling heifer, or a first time heifer (when she has her first calf). After giving birth to the second calf she will then be termed as a mature cow.
A calf is any young bovine. A heifer is a young cow (female) who has not calved yet.

Answer 3

Cows are mature female bovines that have had a calf. Steers are castrated male bovines.

Neither, both, or either may have horns depending on the breed, whether that particular breed has expressed polled characteristics or not, or if they have been dehorned when young.

Answer 4

Steers are male bovines that have been castrated prior to maturity. Some call them "castrated bulls" but this is really incorrect since steers look nothing like bulls. Stags are more "castrated bulls" because they still retain bullish characteristics because of the fact that they've had their testes removed after reaching sexual maturity.

Bulls are intact male bovines that are used for breeding purposes. A bull is a bull from the time it is a year old until death.

An ox (plural: oxen) is a bovine that has been trained for draft work, such as pulling plows, wagons, and cats. Most oxen are male bovines castrated after puberty, though many oxen are intact males and females merely trained for their ability to pull heavy objects that a single human cannot do him/herself.
