Nutritional Factors Involved in Wool Production By Merino Sheep II. The Influence of Copper Deficiency on the Rate of Wool Growth and on the Nature of the Fleece

Abstract

A range of nutritional states which varied in relatively small degrees from a normal physiological condition to one of acute copper deficiency was induced in a series of evenly matched groups of Merino sheep depastured on deficient terrain by providing them with supplements of copper which extended through suboptimum: amounts to quantities in excess of their full requirements.
