The objective of this study was to compare the productive and technological characteristics of alpaca fiber in two alpaca companies of Cerro de Pasco. The information was collected on 457 tuis alpacas between females and males with an average age of 420 days, belonging to the Racco and Gacocen nucleus group, during the shearing of the years 2016 and 2017. The data of Live Weight at shearing (LW) and Greasy Fleece Weight (GFW) were determined with the use of a precision balance and the Staple Length (SL) was measured with a millimeter rule in the area of the middle ribs; fiber samples were also taken for the analysis of average Fiber Diameter (FD), the average fiber Diameter Coefficient of Variation (CVD) and Comfort Factor (CF) using the IWTO 12-2012 method. In the statistical analysis, age (days) was included as a linear covariate and as fixed effects the year, sex and company with their corresponding interactions. The results showed average values of: LW 38.45 kg and 39.95 kg; GFW 2.23 kg and 1.72 kg; SL 13.39 cm and 14.08 cm; FD 18.49 μm and 18.62 μm; CVD 21.67% and 20.92%; CF 98.03% and 98.61% for the companies of Racco and Gacocen, respectively. Were observed the interactions between company and year for LW, GFW, SL and CF; between company and sex for LW, SL, FD and CVD, and for sex and year only SL; According to the results obtained, both companies are within the average values that correspond to an organization with medium technological level, being Racco significantly different in the GFW. Company-year were found interactions for LW, GFW, SL and CF; between company-sex for LW, SL, FD and CVD, and for sex-year only on SL. It is concluded that the productive and technological characteristics of alpacas tuis fiber in both alpaqueras companies are within the average values that correspond to an organization with medium technological level, being Racco the one that obtained the highest PVS in the year 2017.
