Fibre quality of South American camelids in Argentina: a review
Argentina’s annual camelidfibre production is estimated at 60 000 kg for llama (Lama glama), somewhat more than 2 000 kg for gua-naco (Lama guanicoe) and about 845 kg for vicuña (Vicugna vicugna). The potential for increasing these amounts is huge consideringthat barely 30 percent of llamas are shor...

| description | Argentina’s annual camelidfibre production is estimated at 60 000 kg for llama (Lama glama), somewhat more than 2 000 kg for gua-naco (Lama guanicoe) and about 845 kg for vicuña (Vicugna vicugna). The potential for increasing these amounts is huge consideringthat barely 30 percent of llamas are shorn and considering the size of the wild camelid population in the country. A compilation ofpublished and unpublished work confirms that almost 50 percent of the llamas are single-coated, about 40 percent have whitefleecesand that averagefibre diameter is about 22 μm in the main llama production area. In general, there is a wide variation infleece weightsandfibre quality between and within herds. However, a llamafleece classing and pricing system is not yet in place to motivate imple-mentation of such programmes. Guanaco and vicuñafleeces are double-coated but thefine undercoat represents more than 80 percent ofthefleece weight. The proportion of downfibre remaining after mechanical dehairing is only 50 percent in guanacos and 70 percent invicuñas. The guanaco undercoatfibre diameter is about 16 μm and vicuñafibre diameter is typically between 13 and 14 μm. Bothfibresare relatively short. Research is needed to establish optimum shearing season and shearing frequency that results infibre qualitydemanded for handcraft and industry in each of the three species. |

La producción anual defibras de camélidos en la Argentina se estima en 60.000 kg de llama (Lama glama), algo más de 2 000 kg deguanaco (Lama guanicoe) y unos 845 kg de vicuña (Vicugna vicugna). El potencial para aumentar esas cifras es enorme considerandoque apenas el 30% de las llamas son esquiladas y considerando el tamaño de las poblaciones de camélidos silvestres de ese país. En unarecopilación de trabajos publicados y trabajos inéditos se confirma que casi el 50% de las llamas tienen vellones de simple capa, el 40%de los vellones son blancos y que el promedio de diámetro defibras es menor a 22 μm. En general se observa una gran variabilidad enpesos de vellón y en caracteres cualitativos de lasfibras entre y dentro de tropas. Sin embargo todavía no hay un sistema de clasificacióncon precios diferenciales que motive al productor a implementar tales programas de mejora. Los vellones de guanacos y de vicuñas sonde doble capa aunque la capa interior representa más del 80% del peso de vellón. El descerdado mecánico deja solo un 50% defibrasfinas de guanaco y 70% defibrasfinas de vicuñas. El diámetro defibras de la capa interior de los guanacos es de aproximadamente16 μm y el de vicuñas está entre 13 y 14 μm. Ambasfibras son relativamente cortas. Es necesario estudiar en los tres camélidos laépoca y la frecuencia de esquila que resulten enfibra de la calidad demandada por artesanos e industria. Fil: Mueller, Joaquin Pablo.
