The Jacob is a rare breed of white-spotted, horned sheep, descended from an ancient European lineage. The North American Jacobs have remained relatively pure, and their body type resembles that of a goat. The name is derived from the Biblical character of Jacob, a shepherd who engaged in some of the first recorded selective breeding of sheep. Jacobs have a medium fleece with no outer coat and very little lanolin, and produce a light, open wool with fiber diameter of 28-33 microns and a Bradford count range of 46s-54s.
