alpaca

[al-pak-uh]
alpaca, partially domesticated South American mammal, Lama pacos, of the camel family. Genetic studies show that it is a descendant of the vicuña. Although the flesh is sometimes used for food, the animal is bred chiefly for its long, lustrous wool, which varies from black, through shades of brown, to white. Flocks of alpaca are kept by indigenous people in the highlands of Bolivia, Chile, and Peru. They feed on grasses growing close to the snow line, and they require a pure water supply.

The Incas had domesticated the alpaca and utilized its wool before the Spanish Conquest, but subsequently the alpaca and the llama were extensively hybridized, leading to a gradual reduction in the amount of high quality alpaca wool. Exporting of alpaca wool to Europe began after Sir Titus Salt discovered (1836) a way of manufacturing alpaca cloth. Breeding alpacas is a small but growing industry in the United States, Canada, and some other non-Andean nations.

Alpacas are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Artiodactyla, family Camelidae.

South American species (Lama pacos) in the camel family (Camelidae). The alpaca, guanaco, llama, and vicuña are closely related and are known collectively as lamoids. Domesticated several thousand years ago by Indians of the Andes Mountains, the alpaca has a slender body, a long neck and legs, a small head, a short tail, and large, pointed ears. Alpacas stand about 35 in. (90 cm) at the shoulder and weigh 120–145 lbs (54–65 kg). They are found in central and southern Peru and western Bolivia, on marshy ground at high altitudes. They are the most important of the lamoids for wool production.

The Alpaca (Vicugna pacos) is a domesticated species of South American camelid. It resembles a small llama in superficial appearance.

Alpacas are kept in herds that graze on the level heights of the Andes of Ecuador, southern Peru, northern Bolivia, and northern Chile at an altitude of 3500 to 5000 meters above sea-level, throughout the year. Alpacas are considerably smaller than llamas, and unlike llamas, alpacas are not used as beasts of burden but are valued only for their fiber. Alpaca fiber is used for making knitted and woven items, much as sheep's wool is. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks, coats and bedding in other parts of the world. The fiber comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States. Alpacas and llamas differ in that alpacas have straight ears and llamas have banana-shaped ears. Aside from these differences, llamas are on average 1-2 feet taller and proportionally bigger than alpacas.

In the textile industry, "alpaca" primarily refers to the hair of Peruvian alpacas, but more broadly it refers to a style of fabric originally made from alpaca hair but now often made from similar fibers, such as mohair, Icelandic sheep wool, or even high-quality English wool. In trade, distinctions are made between alpacas and the several styles of mohair and luster.

Background

Alpacas have been domesticated for thousands of years. In fact, the Moche people of Northern Peru often used Alpaca images in their art. There are no wild alpacas. The closest living species are the wild Vicuña, also native to South America. Along with Camels and Llamas, the Alpaca are classified as Camelids. The Alpaca is larger than the Vicuña but smaller than the other Camelid species.

Of the various Camelid species, the Alpaca and Vicuña are the most valuable fiber-bearing animals: the alpaca because of the quality and quantity of its fiber, and the vicuña because of the softness, fineness and quality of its coat. Alpacas are too small to be used as pack animals. Instead, they were bred exclusively for their fiber and meat

Alpaca meat was once considered a delicacy by Andean inhabitants. A recent resurgence in Alpaca meat was curtailed by a recent change to Peruvian law granting the Alpaca protected status. Today, it is illegal to slaughter or trade in Alpaca meat. Because of the high price commanded by Alpaca on the growing North American Alpaca market, illegal Alpaca smuggling has become a growing problem.

Alpacas and llamas can (and do) successfully cross-breed. The resulting offspring are called huarizo, which are valued for their unique fleece and often have gentle temperaments and are suitable for pets.

Behavior

Alpacas are social herd animals that live in family groups consisting of a territorial alpha male, females and their young. They are gentle, elegant, inquisitive, intelligent and observant. As they are a prey animal, they are cautious and nervous if they feel threatened. They like having their own space and may not like an unfamiliar alpaca or human getting close, especially from behind. They warn the herd about intruders by making sharp, noisy inhalations that sound like a high pitch burro bray. The herd may attack smaller predators with their front feet, and can spit and kick. Due to the soft pads on their feet, the impact of a kick is not as dangerous as that of a hoofed animal, yet it still can give quite a bruise, and the pointed nails can inflict cuts.

Spitting

Not all alpacas spit, but all are capable of doing so. "Spit" is somewhat euphemistic; occasionally the projectile contains only air and a little saliva but alpacas commonly bring up acidic stomach contents (generally a green grassy mix) and project it onto their chosen target. Spitting is mostly reserved for other alpacas, but an alpaca will occasionally spit at humans that, for example, take away food.

For alpacas, spitting results in what is called "sour mouth." Sour mouth is characterized by a loose-hanging lower lip and a gaping mouth. This is caused by the stomach acids and unpleasant taste of the contents as they pass out of the mouth.

Some alpacas will spit when looked at, others will never spit—their personalities are very individualized and there is no hard and fast rule in terms of social behavior, although there is often a group leader, and a group trailer/runt that is picked on by others.

Physical contact

Once they know their owners and feel confident around them, alpacas may allow their backs and necks to be touched. They do not like being grabbed. Once socialized well, some alpacas tolerate being stroked or petted anywhere on their bodies, although many do not like their feet, lower legs, and especially their abdomen touched or handled. If an owner needs to catch an alpaca, the neck offers a good handle—holding the neck firmly between the arms is the best way to restrain the animal. Holding the neck from the rear with the animal's head under one's arm is also very effective.

Hygiene

To help alpacas control their internal parasites they have a communal dung pile, where they do not graze. Generally, males have much tidier, and fewer dung piles than females who tend to stand in a line and all go at once. One female approaches the dung pile and begins to urinate and/or defecate, and the rest of the herd often follows.

Because of their preference for using a dung pile, some alpacas have been successfully house-trained.

Sounds

Individuals vary, but Alpacas generally make a humming sound. Hums are often comfort noises, letting the other alpacas know they are present and content. The humming can take on many inflections and meanings, from questioning to a high-pitched, almost desperate, squealing when a mother is separated from her offspring.

Alpacas make a variety of sounds. When they are in danger, they make a high-pitched, shrieking whine. Some breeds are known to make a "wark" noise when excited. Strange dogs—and even cats—can trigger this reaction. To signal friendly and/or submissive behavior, alpacas "cluck," or "click" a sound possibly generated by suction on the soft palate, or possibly in the nasal cavity. This is often accompanied by a flipping up of the tail over the back.

When males fight they also scream, a warbling bird-like cry, presumably intended to terrify the opponent. Fighting determines dominance, and therefore the right to mate the females in the herd, and it is triggered by testosterone. This is why males are often kept in separate paddocks—when two dominant males get together, violent fights often occur. When males must be pastured together, it is wise to trim down the large fang-like teeth used in fights, called "fighting teeth". Although alpacas may try to bite each other, they only have a bottom row of teeth, so damage is usually minimal. When fighting they will often tangle others necks and attempt to push each other around, but they settle down after a week, as they establish dominance.

When alpacas breed, males make a similar noise called an "orgle". This is thought to possibly stimulate ovulation in the female. This can sound like a warbling or gargling noise in the back or the throat, possibly generated by movement of the tongue.

Reproduction

A male in the act of mating, or hoping for a chance to mate, "orgles" (sings). This orgling helps to put the female in the mood, and it is believed to also help her to ovulate after mating.

Females are "induced ovulators," which means that the act of mating and the presence of semen causes them to ovulate. Occasionally, females conceive after just one breeding (which can last anywhere from 5 minutes to well over an hour; the males are "dribble ejaculators,") but occasionally do have troubles conceiving. Artificial insemination is technically difficult because the act of breeding stimulates ovulation - but it can be accomplished. Babies conceived from artificial insemination are not registerable with the Alpaca Registry.

A male is usually ready to mate for the first time between one and three years of age. A female alpaca may fully mature (physically and mentally) between 12−24 months. It is not advisable to allow a young female to be bred until she is mature, as over breeding a young female before conception is possible is a common cause of uterine infections. As the age of maturation varies greatly between individuals, it is usually recommended that novice breeders wait until females are 18 months of age or older before initiating breeding.

The young male's penis is attached to the prepuce, and generally does not detach until one to two years of age. The penis is a very long, thin, prehensile organ that is perfectly adapted for the task of finding the vaginal opening despite a fluffy tail, penetrating the hymen (if present,) navigating the vaginal canal and entering the cervical opening, where deposit of the semen occurs.

Pregnancies last 11.5 months ± 2 weeks, and usually result in a single offspring or cria. Twins are rare, approximately 1/1000, slightly rarer than the proportion of twins in human births. After a female gives birth, she is generally receptive to breeding again after approximately two weeks. Crias may be weaned through human intervention at approximately 6 months and 60 pounds. However, many breeders prefer to allow the female to decide when to wean her offspring. Offspring can be weaned earlier or later depending on their size and emotional maturity.

It is believed that alpacas generally live for up to 20 years and occasionally longer. Conditions and nutrition are better in the USA, Australia, New Zealand and Europe than in South America, so animals live longer and are healthier.

History of the scientific name

In the 18th and 19th centuries, the four South American camelid species were assigned scientific names. At that time, the alpaca was assumed to be descended from the llama, ignoring similarities in size, fleece and dentition between the alpaca and the vicuña. Classification was complicated by the fact that all four species of South American camelid can interbreed and produce fertile offspring. It was not until the advent of DNA technology that a more accurate classification was possible.

In 2001, the alpaca genus classification changed from Lama pacos to Vicugna pacos following the presentation of a paper on work by Dr Jane Wheeler et al on alpaca DNA to the Royal Society showing that the alpaca is descended from the vicuña, not the guanaco.

The relationship between alpacas and vicuñas was disputed for many years, but Wheeler's DNA work proved it. However, many academic sites have not caught up with this, so it is something well known to alpaca breeders who have read Hoffman's book, and to Royal Society members who have access to the current classification data, but not more widely known.

Poisonous to Alpacas

Many plants are poisonous to the Alpaca, including the bracken fern, fireweed, oleander, and some azaleas. In common with similar livestock, others include: Acorns, African rue, Agave, Amaryllis, Autumn Crocus, Bear Grass, Broom Snakeweed, Buckwheat, Ragweed, Buttercups, Calla lily, Orange tree, Carnations, beans from the Castor Oil plant, Cress and a great many others.

Fiber

Alpaca fleece is a light-weight, lustrous and silky natural fiber. While similar to sheep’s wool in that it is a natural fiber, it is warmer, not prickly, and bears no lanolin which makes it hypoallergenic . It is also soft and luxurious. In physical structure, alpaca fiber is somewhat akin to hair, being very glossy, but its softness and fineness enable the spinner to produce satisfactory yarn with comparative ease. It is hollow as well, which makes it a good insulator. The preparing, carding, spinning, weaving and finishing process of alpaca is very similar to the process used for wool.

Prices

The price for American alpacas can range from USD$100 for a desexed male or gelding to USD$500,000 for the highest of champions in the world, depending on breeding history, sex, and color. It is possible to raise up to 10 alpacas per acre (25 alpacas per hectar) as they have a designated area for waste products and keep their eating area away from their waste area, which helps to avoid diseases. But this ratio differs from country to country and is highly dependent on the quality of pasture available (in Australia it is generally only possible to run one to three animals per acre due to drought). Fiber quality is the primary variant in the price achieved for alpaca wool; in Australia it is common to classify the fiber by the thickness of the individual hairs and by the amount of vegetable matter contained in the supplied shearings.
