Herder

A herder is a pastoral worker responsible for the care and management of a herd or flock of domestic animals, usually on open pasture. It is particularly associated with nomadic or transhumant management of stock, or with common land grazing. The work is often done either on foot or mounted.

Depending on the type of animal being herd, the English language can give different professional names, for example, cowboy for cows, shepherd for sheep, or goatherd for goat.
