Lacaune sheep are the most
numerous sheep breed in France. They have been selected in France for increased
milk production under a sophisticated selection program incorporating
artificial insemination, milk recording, and progeny testing of sires for
longer than any other dairy sheep breed in the world.
Annual genetic improvement for
milk yield in the French Lacaune is estimated at 2.4% or 5.7 kg (12.5 lbs).
Lacaune ewes produce milk with higher total solids than the East Friesians, but
in slightly less volume.The sheep of the Lacaune breed produce the milk which
is responsible for the famous Roquefort cheese.
