Agneau Gris is the French term for "Gray lamb", sometimes called Agneau Broutart which is slaughtered when it is between 180 and 270 days old and weighs 30 to 40 kilograms (66 to 88 pounds). This lamb is mostly grass-fed with some additional cereal grains. The fat is no longer white hence the name "gray lamb", however, the meat is firmer and more fully flavored, which some people prefer.
