cowhand
A worker on a ranch who cares for and moves cattle.
A cowhand is someone who works on a cattle ranch, taking care of cows and horses. Cowhands spend their days riding across wide ranges of land, herding cattle from one grazing area to another, checking on sick or injured animals, and making sure fences stay in good repair. They might help brand calves (marking them with the ranch's symbol), round up cattle for transport to market, or break in young horses so they can be ridden.
The job requires real skill: a good cowhand knows how to rope a running calf, read weather signs, and handle a horse in rough terrain. In the American West during the 1800s, cowhands (also called cowboys or cowgirls) drove massive herds of cattle hundreds of miles along trails from Texas to railroad towns. Today's cowhands use pickup trucks and ATVs alongside their horses, but the core work remains the same.
The word hand here means worker, the same way sailors were once called deckhands. A ranch might employ several cowhands, each responsible for different parts of the vast property where cattle roam and graze.
