The relationship between greasy fleece weight and clean fleece weight and its application

Abstract

For seven flocks examined there was a high correlation between greasy and clean fleece weights. At low culling levels, selection of sheep on greasy fleece weight is sufficient, but at higher selection intensities, scouring fleece samples to estimate clean weight is justified. A judicious combination of culling for low greasy fleece weight and selection for high clean fleece weight can be expected to give most of the potential gain in clean fleece weight, with a considerable saving of time and labour.
