英文摘要	The nutritional value, whey protein, and the fatty acid (FA) composition of milk from four South American camelids (SAC) (vicuna, Vicugna vicugna (Molina, 1782); alpaca, Vicugna pacos (Linnaeus, 1758); guanaco, Lama guanicoe (Muller, 1776); llama, Lama glama (Linnaeus, 1758)) were evaluated and compared with milk from old-world camelids. Samples were collected from healthy animals from the northwest (llama, alpaca, and vicuna) and Patagonia (guanaco) areas of Argentina. Gross composition of milk from SAC showed a higher protein, lactose, and lipid content than camel milk. Serum albumin and alpha-lactalbumin were the dominant whey proteins, followed by immunoglobulin G (IgG). The FA profile showed from 4: 0 to 24: 0 FA, with a high level of conjugated fatty acid (CLA; 1.05-1.64 g/100 g of FAME) and its precursor, vaccenic acid. Desaturase activity of C16 and CLA was quite similar between species but was significantly different for C14. Camelid milk showed a lower atherogenicity index than ruminant milk. This is the first time that a comparative study involving four species of SAC was carried out to contribute to the general knowledge of the physiology of new-world camelids. Their milk was determined to be of high nutritional quality, allowing it to be considered an alternative food item for humans in the semi-arid region of South America.
