The Growth and Composition of Wool III. Variations in the Sulphur Content of Wool

Abstract

The sulphur content of wool was measured during experiments in which the nutritive status of sheep was altered by changes in the amount or composition of the diet. Three experiments were carried out, involving 13 sheep and five diets given at different levels of feeding. Wool grown on delineated areas was collected and its clean dry weight and sulphur content were determined. Wool growth rates varied between 0·3 and 1· 8 mg clean dry wool/cm2/day.
