The vicuña is an emblematic species of fauna conservation in Peru. The vicuña population recovered after several years of timely measures for their conservation, moving to appendix II of CITES. Currently there are vicuñas that are kept free (silvestry) and populations kept enclosed in permanent fences (captivity). During 2018, 58 programmed captures (known as Chacus) were done in the Cusco Region, capturing 6777 animals, corresponding to 3229 and 3548 heads for silvestry and captivity, respectively. The age distribution in the case of juveniles was higher in silvestry (18.08%) with respect to the captivity system (7.2%), which would be evidence of the existence of higher mortality in this population. The 2012 national census indicated a higher proportion of female vicuñas in the general population of the Cusco Region; however, in this work similar populations were found by sex in bot...

This aim of this study was to describe the fibre diameter and fleece weight of vicuñas in the Cusco Region, Peru. The fibre diameter of 302 fibre samples of young, juveniles and adult vicuñas were evaluated using an OFDA 2000® equipment. The samples were collected in different programmed captures (called Chaccus) under two management systems: wildness and semi-captivity. In addition, 633 fleeces were weighed and differentiated by age, sex and type of management of the animals. The present study was authorized through the Resolution of General Direction N.° 180-2016-SERFOR/DGGSPFFS. The average fineness of the fibre of young (13.24 μm), juveniles (12.03 μm) and adults (12.72 μm) was determined. The fineness of fibre for males and females was 12.99 and 13.53 μm in young, 12.06 and 12.02 μm in juveniles and 12.88 and 12.58 μm in adults respectively. The smallest diameter of the fi...
