The Debouillet is a breed of domestic sheep originating from Tatum, New Mexico.
It was developed in the 1920s through crossing Rambouillet and Delaine Merino sheep and the breed's name is a portmanteau of these two ancestors.
[2] Specifically adapted to the arid ranges of the Southwestern U.S., the breed is a medium–size sheep with long, fine wool.
The fleece from mature ewes will weigh 10 to 18 lb (4.5 to 8.1 kg) with a 35% to 50% yield.
The staple length of the fleece is from 3 to 5 in (7.5 to 12.5 cm) with a numerical count of 62 to 80, which is 18.5 to 23.5 microns in diameter.
