Competition between Skin Follicles in Sheep

Abstract

IN sheep, the density and fineness of the fleece are closely correlated. The denser fleeces are finer and shorter. This leads to the suggestion that the quantity of fibre formed by a follicle is to a large extent governed by the number of follicles which are close to it, and therefore to the concept that adjacent follicles compete with each other for a limited amount of fibre substrate. Evidence in support of this hypothesis can be deduced from several very different aspects of the growth of the fleece.
