Abstract

The diameter and the distribution of diameters of fibers in alpacas are important for the determination of the quality, appearance and comfort of the product. However, these parameters are not exactly resolute for alpaca populations, due to conceptual and procedural deficiencies that slant their estimates. The present work establishes reference values for the average, standard deviation and others of the diameter of the fiber in alpacas of the region Puno, as well as it evidences deficiencies and weaknesses of the carried-out determinations. It was analyzed two groups of samples of fleece of alpacas, being executed diameter determinations through the projection microscope and the OFDA. It was used summary procedures and analysis of data of Descriptive Statistic.  It was determined that the fiber diameter, the means of the fiber diameters, is distributed as a function Gamma. The average and standard deviation for the fiber diameter in alpacas of the region Puno was of 23.42 ± 6.08 µm obtained by of the Gamma function parameters. The average and standard deviation obtained of the distributions of means are not real, and they are smaller since they use a different variable that reduces the range of the values of fiber diameter. 8.95 % fibers in alpacas corresponds to the thickest area. More than 60.00 % of the fibers of alpacas of the region Puno has a smaller diameter to 23 µm, that guarantees the quality of the fiber of the alpacas of this region.
