Resumen

The aim of this study was to determine the characteristics of Huacaya and Suri alpaca fiber: mean fiber diameter (MFD), standard deviation of fiber diameter (SDFD), coefficient of variation (CV), comfort factor (CF), and curvature index (CI) based on breed, sex and age. A total of 454 fiber samples were collected from Huacaya and Suri alpacas aged Milk-teeth, 2-teeth, 4-teeth and Full-mouth, which were analyzed at the Fiber Laboratory of the Dis-trict Municipality of Corani, using OFDA 2000 equipment. Huacaya alpacas exhibited smaller fiber diameters by sex (Male: 19.99 µm and females: 20.66 µm) compared to Suri alpacas (Male: 23.13µm and females: 23.13 µm). In terms of comfort and curvature index variables, both breeds displayed similar trends, but Huacaya had better values than Suri.
