Lamb, hogget, and mutton (UK, New Zealand and Australia) are the meat of domestic sheep. The meat of a sheep in its first year is lamb; that of a juvenile sheep older than one year is hogget; and the meat of an adult sheep is mutton. Distinct from the meat, a lamb (singular with the indefinite article) or lambs (plural) also describes live juvenile sheep, which may or may not be used for meat. In Australia, the term prime lamb is often used to refer to lambs raised for meat.
