A model to estimate the economic value of using individual fleece fibre diameter measurements to class wool

Abstract

Woolclassing in Australia traditionally relies upon a subjective visual appraisal of fleeces. A new approach to woolclassing, termed objective classing, has been adopted by some woolgrowers. In objective classing, fine and broad lines of wool are created using pre-measured individual fibre diameter data, rather than the subjective appraisal of the classer. This paper describes a computer model that estimates the clip preparation that maximises net return, and the expected economic value of objective classing. The effect of mean and standard deviations of fibre diameter, test precision, wool market conditions, and clip preparation on expected economic value was examined. Results indicated tha..
