The present study aimed to compare technological parameters of Creole sheep wool according to animal class and the wool character. The study was carried out in the region of Pasco corresponding to the year 2016 in 11 localities where samples of 21 herds were taken, out of a total of 794 heads that were analyzed using the OFDA 2000 equipment. A descriptive and Pearson correlation analysis was made for the technological characteristics of wool, then an analysis of variance was performed using a mixed model, including herd as a random effect and the animal class (Ewe hogget, Ram hogget, Ewe, Ram) and wool character (Good, Fair and Bad) as fixed effects; Tukey's test was used for the comparison of means. The results showed average values of fiber diameter (MFD) of 24.66 ± 0.09μm, with a coefficient of variation (CVFD) of 20.92 ± 0.16%, comfort factor (CF) of 85.93 ± 0.39% and curvature index (CI) 89.26 ± 0.67º / mm; the significant phenotypic correlations were between MFD and CF (-0.90), MFD and CI (-0.38), MFD and CVFD (-0.29), CF and CI (0.41), CF and CVFD (0.48) and CI and CVFD (0.30). When the analysis of variance was performed, it was determined that herd effect was relevant to explain the variability of the technological parameters on study, showing the curvature index the highest variance between herds; also, significant differences were found between animal classes and wool character. It is concluded that there is a significant effect of the wool character in all the technological parameters, while the animal class was significant for all except the CVDF, which gives us precise information to improve the selection processes of creole sheep producers.
