Abstract

Background: The fibre characteristics of fleece weight (FW), mean fibre diameter (MFD), coefficient of variation of mean fibre diameter (CVMFD) and common phenotypic correlations between them of Huacaya alpacas (Vicugna pacos) breed, were estimated on 959 one-year-old animals, under extensive rangeland management conditions. 
Methods: Samples were taken between 2005 and 2018 (male and female), of two coat colors (white and brown), at the Toccra CEDAT-DESCO Alpaca Development Center (Arequipa, Perú). Model were developed an they included year, sex and coat color and their interactions with FW, MDF and CVMDF of alpaca’s fibre under the experimental design was completely randomized with a factorial arrangement of 12×2×2. 
Result: Statistical significant effect was for year of birth × sex interaction when FW was analyzed while year of birth × color interaction explained MFD and CVMFD variation (p<.001). Phenotypic correlation calculated by Pearson’s coefficient showed that FW was positively correlated with MFD (0.24) while CVMFD was positively correlated with MFD (0.10). Results from this study indicated that the FW was influenced by both year of birth and sex, while MFD and CVMFD were influenced by both year of birth and color. Overall, it was concluded that a genetic progress can be achieved in the huacaya alpaca breed of CEDAT genetic improvement program.
