Llamas, alpacas, guanacos and vicunas are collectively known as New World Camelids. Originally they all came from Central America. They are all members of the camelid family and are related to Bactrian and Dromedary camels.
Llamas are traditionally pack animals. In the U.K. they are usually kept for trekking or as companion animals. Alpacas are primarily kept for their excellent fibre. There are only a few guanacos and vicunas kept in the UK.
All camelids are naturally herd animals and should preferably not be kept in isolation. They will live happily with other animals. Average stocking rates are 4-5 llamas/acre (0.5ha) or 6-8 alpacas/acre (0.5ha). They require an open fronted shelter.
