The aim of this study was to analyse the production of vicuña (Vicugna mensalis mensalis) fibre in semi-captivity and in the wild between 2008 and 2016 in the Apurímac region of Peru, as well as to determine the population of vicuñas captured and sheared and the effect of sex, age and management system in the fibre production. The production of vicuña fibre in the nine years of the study was 2 623 kg, annual average of 295.7 kg, yield of 152.76 g/vicuña and a range of variation of 54-426 g. Fibre production had an annual growth rate of 9.45% and a capture rate of 10.34%. Factorial analysis showed a significant difference (p<0.05) for the interactions of years, age, sex and simple effects.

La vicuña en la región Apurímac es un recurso zoogenético y una alternativa económica para el poblador alto andino, el cual se encarga del usufructo de dicha especie mediante las practicas ancestrales denominadas chacu. Dada la importancia de la fibra de vicuña y falta de información sobre la situación actual de la producción de fibra de vicuña en la región de Apurímac se procedió a realizar esta investigación con el objetivo de analizar la producción de fibra de vicuña (Vicugna vicugna mensalis) en Semicautiverio y Silvestria del 2008 al 2016 en la región de Apurímac, así mismo determinar la población de vicuñas capturadas y esquiladas y determinar la interacción entre los factores sexo, edad, sistema de manejo y año en la producción de fibra. Se utilizó estadística descriptiva (análisis de dispersión y de tendencia central), histogramas y tasas de captura y ...
