Fleece Density: we use a fleece density index (FDI) which 'calculates' the density of an animal taking into consideration the weight, micron, sd and length of the fleece. As we are still trialling the index and comparing the results to actual skin biopsies, we have not provided the numerical results, but have illustrated these results in the density indicator graph for each animal. Once we have confirmed the acuracy of the FDI, we will provide the actual calculated score, which should correspond to the follicle density in a skin biopsy.
