Correlation between parts of the Merino fleece and the subsequent influence on income.


The fleeces of 160 one· year old ewes were classed and separated according to the standards of the National Wool Growers' Association into 'fleece wool', BKS (inclUding BKS 2), BP (including CB and CBP) and LOX. Each part of the individual fleece was weighed and staple length, fibre diameter, clean yield and price per kilogram was determined. Fleece wool contributed almost 50% of the total price of the whole fleece, whereas the contributions of BKS, BP and LOX were 27,2; 13,4 and 9,5% respectively. Correlation coefficients for most characteristics between the various parts of the fleece are in most cases relatively high. Clean yield (r = 0,731 to 0,879) and fibre diameter (r = – 0,486 to – 0,661) are the most important contributors to price of wool. Greasy mass, per cent clean yield, fibre diameter and staple length are responsible for 97,4% of the variation in price of fleece wool and 98,4% in the price of BKS.
