n.
Live sheep before the age of one year, and the flesh of such animals.
The flesh of the mature ram or ewe at least one year old is called mutton; the meat of sheep 1220 months old may be called yearling mutton. The meat of sheep 610 weeks old is usually sold as baby lamb, and spring lamb comes from sheep 56 months old. The primary lamb-and mutton-consuming countries (on a per capita basis) are New Zealand and Australia.
