short-fine fibers was 7.3 cm, and that of kemp fibers was 1.5 cm. Within the samples, the long-coarse proportion was 1.5% and the short-fine proportion was 94.1%. The yield after alcoholic scouring was more than 80%, which explains the little amount of grease in wool. The medium fiber diameter was 30.6 µ; the histograms of frequency in diameter distribution confirm the existence of single-layer wool. The Xisqueta breed can be included into the entrefine group. In the comparative study with other ovine breed, the Xisqueta breed appears into a cluster that includes other breeds belonging to the celtiberian entrefine trunk, such Aranese, Manchega and Ripollesa.
