LLAMA (Large Latin America Millimeter/submillimeter Array) is a new radio observatory that is being constructed in a collaboration between Argentina and Brazil. It will consist of a 12 meters diameter antenna that is being installed in Alto Chorrillos at 4850 m of altitude, in the Salta province of Argentina. Alto Chorrillos is a high-quality astronomical site similar to Chajnantor (Chile), where ALMA observatory operates. When completed, LLAMA will allow line, continuum and linear polarization observations between 35 and 700 GHz, approximately. For the first light, LLAMA will be equipped with ALMA-like receivers at bands 5 (163 - 211 GHz), 6 (211 - 275 GHz) and 9 (602 - 720 GHz). LLAMA is being planned to be a versatile astronomical facility that will serve the scientific community for the exploration of scientific topics as diverse as the molecular evolution of the Universe, black holes and their accretion disks, astrophysical jets, stellar formation and evolution, the structure of our galaxy and the Sun, planetary atmospheres and extragalactic astronomy. In this work, I will present the LLAMA project and the perspectives for this new astronomical facility in the context of the investigation of galactic and extragalactic masers.

Argentina's annual camelid fibre production is estimated at 60 000 kg for llama (Lama glama), somewhat more than 2 000 kg for guanaco (Lama guanicoe) and about 845 kg for vicuña (Vicugna vicugna). The potential for increasing these amounts is huge considering that barely 30 percent of llamas are shorn and considering the size of the wild camelid population in the country. A compilation of published and unpublished work confirms that almost 50 percent of the llamas are single-coated, about 40 percent have white fleeces and that average fibre diameter is about 22 µm in the main llama production area. In general, there is a wide variation in fleece weights and fibre quality between and within herds. However, a llama fleece classing and pricing system is not yet in place to motivate implementation of breeding programmes. Guanaco and vicuña fleeces are double-coated but the fine undercoat represents more than 80 percent of the fleece weight. The proportion of down fibre remaining after mechanical dehairing is only 50 percent in guanacos and 70 percent in vicuñas. The guanaco undercoat fibre diameter is about 16 µm and vicuña fibre diameter is typically between 13 and 14 µm. Both fibres are relatively short. Research is needed to establish optimum shearing season and shearing frequency that results in fibre quality demanded for handcraft and industry in each of the three species.

The aim of this study was to establish reference interval for biochemical parameters in blood of alpacas on the basis of large population of clinically healthy animals, and to determine the influence of sex, age and season on nitrogen and lipid metabolites, enzymes, electrolytes, vitamins and minerals in blood of alpacas. Blood samples were collected from 311 alpacas (61 males and 201 females >6 months of age and 49 crias (21 males and 28 females) ⩽6 months of age). Selected farms were located in Central Europe (Czech Republic and Germany). We determined 24 biochemical parameters from blood serum. We performed the comparison of results by the sex of animals and for the older group also the comparison of the results with regard to the season, respectively, to the feeding period. We found no highly significant difference (P<0.01) between males and females with the exception of γ-glutamyl transferase (GGT), alkaline phosphatase (ALP) and cholesterol. We found 15 significantly different parameters between the group of crias 6 months of age and the older alpacas. Based on our findings we suggest for most parameters to use different reference intervals (especially ALP, cholesterol, total protein, globulin, non-esterified fatty acids (NEFA), GGT and phosphorus) for the two above-mentioned age groups. Another important finding is the differences between some parameters in older group of alpacas in summer/winter feeding period. Animals in the summer feeding period have higher values of parameters related to fat mobilization (β-hydroxybutyrate, NEFA) and liver metabolism (bilirubin, alanine aminotransferase). The winter period with increased feeding of supplements with higher amount of fat, vitamins and minerals is characteristic by increased values of cholesterol, triglycerides, vitamins A and E, and some minerals (K, Ca, Mg and Cl) in blood serum. Clinical laboratory diagnosis of metabolic disturbances may be improved with use of age-based reference values and with consideration of seasonal differences.

Hair follicle and fibre characteristics of Peruvian alpaca and llama and Bolivian llama were analysed in three experimental studies. The first experiment was designed to determine the age at which all the secondary follicles reach maturity, as well as to compare the skin follicular structure and activity among these different types of Peruvian camelids. It is concluded that the South American camelids investigated in this study gained a complete and mature skin follicle apparatus at an early age, and hence producers should practise an early first shearing. A second Peruvian experiment investigated comparative fibre cuticular structure on twenty Peruvian domestic camelids comprising huacaya, suri and llama (woolly) ‘chacos’ genotypes. The results showed that the number of cuticular scales per 100 μm fibre length proved to be strongly affected by both the fleece type and the fibre diameter. The suri fleece was clearly differentiated from those of both huacaya and llama by possessing the highest percentage of fibres with a number of scales less than eight, the lowest percentage of fibres with more than nine scales, along with the lowest percentage of fibres with a diameter of more than 35 μm. It is concluded that, with the exception of the scale height, the cuticular parameters investigated in this study can be utilised in textile fibre analyses for distinguishing among these three types of fleece, as well as in selection projects designed to produce homogeneous fibres from Peruvian domestic camelids. A further study was conducted to determine the age at which the hair follicles in Bolivian llamas reach maturity as well as for comparing the skin follicular structure and activity between the two distinct genotypes. Thirty-one llama kids were chosen. They were born between January and April 1998 and were of different sex and of ‘Q’aras’ (or Carguera) or ‘T’amphullis’ type. Skin biopsies were taken from the right mid-costal region at 2, 4, 6, 8,10,12 and 14 months of age in order to monitor four follicular parameters. In this experiment, secondary to primary (S/P) data show that the Bolivian llama population analysed possessed a complete and mature skin follicle apparatus at birth that remained essentially constant throughout the investigation period. Due to the variation of these traits inside the same genetic population, the present results showed that T and Q types could only be subjective on the basis of S/P ratio.

More 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 strategy involving a sustained investment in appropriate R&D.
