PARES, Pere-M  y  PEREZGROVAS, Raúl. Fleece and fiber analysis in the Xisqueta ovine breed. Rev. Fac. Cienc. Vet. [online]. 2009, vol.50, n.1, pp.53-58. ISSN 0258-6576.

The indigenous breed Xisqueta, which pertains to the historic Iberian trunk, was studied in order to establish the characteristics of its wool. Samples from lateral medial zone were taken in 21 adult sheep and submitted for their analysis. The medium length of long-coarse fibers was 12.4 cm, that of 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.
