Pastoralists are people who rear animals as their primary source of livelihood. They depend on animal husbandry for food, clothing, and to earn a living. Some synonyms of pastoralists are herders, grazers, ranchers, and livestock keepers. All of these terms refer to people who engage in the husbandry of animals. Herders and grazers indicate individuals who move their animals around different grazing lands. Ranchers, on the other hand, usually own a specific area of land where they raise their herds. Livestock keepers care for their animals in a specific location and may feed them with crops and fodder that they grow in their fields. Synonyms are useful in providing different ways of referring to a particular group of people.
