Ram toby jug produced by Longpark Pottery of Torquay, England, circa 1910. A ram is a male sheep, which is a domesticated, ruminant mammal typically kept as livestock. Domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe, an intact male as a ram, a castrated male as a wether, and a young sheep as a lamb. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. The ram's horns form the handle of the jug.
