Lamb and mutton

Lamb, hogget, and mutton are the meat of domestic sheep (species Ovis aries) at different ages.

A sheep in its first year is called a lamb, and its meat is also called lamb. The meat of a juvenile sheep older than one year is hogget; outside North America this is also a term for the living animal. The meat of an adult sheep is mutton, a term only used for the meat, not the living animals. The term mutton is sometimes used to refer to goat meat in the Indian subcontinent.
