ResumenMás de un millón de pequeños productores de los Andes centrales de Sudamérica tienen alpacas (Vicugna pacos) y llamas (Lama glama) como principal medio de subsistencia. Los animales proveen carne, leche, fibra, energía de transporte y guano y, además, son un elemento importante de la identidad cultural de sus pueblos. Con 3,9 millones de llamas y 3,3 millones de alpacas la producción total de fibras de camélidos en la región supera los 5 millones de kg anuales. Cerca del 30% de la producción de fibra se transforma y es usada a nivel de predio o comunidad. Alrededor del 80% de la alpaca comercializada es de color blanco y el 12% tiene diámetros de fibra menores de 23 micrones. Las fibras de llama son de menor valor y más variables en colores y diámetros que las fibras de alpaca. Ambas especies tienen dos razas, cada una con características de calidad de fibra y adaptación específica. También existen en Sudamérica dos especies de camélidos silvestres, el guanaco (Lama guanicoe) y la vicuña (Vicugna vicugna). Ambas tienen vellones de valiosa fibra down. Poblaciones específicas de estos camélidos califican para ser capturadas, esquiladas y liberadas generando un ingreso adicional a las comunidades en que viven. El aumento de la producción de fibras y demás productos de los camélidos sudamericanos, a la vez de preservar un recurso genético animal crítico y los valores culturales asociados y mejorar la calidad de vida de muchos pequeños productores, debe ser parte de una estrategia global de inversión sostenida en investigación y desarrollo apropiados.Palabras clave: alpaca, llama, vicuña, guanaco SummaryMore than one million smallholders in the Andean region of central South America exploit alpacas (Vicugna pacos) and lamas (Lama glama) as their main means of subsistence. Alpacas and lamas provide meat, milk, fibre, power and guano; in addition it is an important element of the cultural identity of their producers. With 3.9 million lamas and 3.3 million alpacas the total annual fibre production in the region exceeds 5 million kg. Nearly 30% of the fibre production is transformed on-farm or at the community level. About 80% of the marketed alpaca fibre is white and 12% is finer than 23 microns. Lama fibres have less value and are more variable in colours and fibre diameter than alpaca fibres. Both species of camelids have two breeds, each one with specific adaptation and fibre quality characteristics. Two wild species of camelids exist in South America: the guanaco (Lama guanicoe) and the vicuna (Vicugna vicugna). Both have fleeces with precious down fibres. Specific populations of these camelids are qualified to be captured, sheared and released, providing an additional income to the communities in which they live. Due to support to improve the production of fibre and other products of South American camelids, while preserving a valuable animal genetic resource, the cultural values of the associated production systems, and improving the livelihoods of resource-poor smallholders should be part of a global strate...

Goat production concentrated in developing countries (tropics, dry areas), contributes largely to the livelihoods of low and medium income farmers. Farming systems in these areas have evolved to cope with the formidable constraints imposed by harsh natural and economic conditions by adapting integrated crop/livestock production strategies. In Asia, Africa and Latin America, due to its almost exclusive extensive nature, goat production relies mainly on grazing on communal lands that hardly provide the minimum nutrient requirements due to overstocking and degradation. While some of these production systems are becoming semi-intensive, appropriate breeding strategies should be designed to promote conservation and improvement of their unique attributes, such as adaptability, water use efficiency and suitability under harsh climatic conditions. In Europe, dairy goat production is more common around the Mediterranean basin, where it is important from an economic, environmental and sociological perspective to the Mediterranean countries: Spain, France, Italy and Greece. Europe owns only 5.1 % of the world's dairy goat herds, but produces 15.6 % of the world's goat milk; this is the only continent where goat milk has such an economic importance and organization. In developing countries the dairy goat sector requires a systemic approach, whereby nutrition, animal health, breeding, know-how, inputs and technologies must be assembled. This would allow the optimization of natural and local resources and would promote the transition from a risk reduction strategy towards an increased productivity strategy. Such an increase would privilege production efficiency based on clean, green and ethical practices for responsible innovation.
