Behaviour
Alpacas are social herd animals and should always be kept with others of
their kind, or at the very least with other camelids. 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 those of hoofed animals, yet they still can give quite
a bruise, and the pointed nails can inflict cuts.
Spitting
Not all alpacas spit, but all are capable. “Spit” is somewhat
euphemistic. While occasionally the projectile contains only air and a
little saliva, they also commonly bring up acidic stomach contents
(generally a green grassy mix) and project it onto its chosen target.
Spitting is mostly reserved for other alpacas, not for
humans, but sometimes a human gets in the line of fire. If an alpaca is
extremely displeased at a human for example taking away of food, that
person may well become covered in smelly, green grassy goo. The smell is
foul and to be avoided at all costs.
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,
they may allow their backs and necks to be touched. They do not like being
grabbed. Once socialized well, most alpacas tolerate being stroked or
petted anywhere on their bodies, although many do not like their feet and
lower legs 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 to 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. However, humming can take on many inflections and meanings, from
a high-pitched, almost desperate, squealing, “MMMM!” or frantic
question, “mmMMM!” when a mother is separated from her offspring
(called a “cria,”) to a questioning “Mmm?” when they are curious.
Alpacas also make other sounds as well as humming. In danger,
they make a high-pitched, shrieking whine. Some breeds are known to make a
“wark” noise when excited, and they stand proud with their tails
sticking out and their ears in a very alert position. 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 somehow 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 is to determine
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 and agree to a winner and dominant male.
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 due to the fact that 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 +/- two weeks and usually result
in a single cria. Twins are rare approximately 1/1000. 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. One of the oldest alpacas in New Zealand (fondly
called Vomiting Violet) died at the end of 2005 at the old age of 29.
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.
Alpaca fibRE
Alpaca fleece is fibre, similar to sheep’s wool in some respects, but
lighter in weight, silkier to the touch, warmer, not prickly, and bears
minimal lanolin which makes it nearly hypoallergenic. It is also soft and
luxurious. Alpaca fleece is made into various exports, from very simple
and inexpensive garments made by the aboriginal communities to
sophisticated, industrially made and expensive products such as suits. In
the United States, groups of smaller alpaca breeders have banded together
to create “fiber co-ops,” to make the manufacture of alpaca fiber
products cheaper.
White is the predominant color of alpacas, because of
selective breeding. However, alpacas come in many shades from a true-blue
black through browns-black, browns, fawns, white, silver-greys, and rose-greys
as well. In South America, the preference is for white. White animals
generally have better fleece than darker-colored animals. This is because
the dark colors had been all but bred out of the animals before the demand
for darker fiber grew up in the United States and elsewhere. In order to
reintroduce the colors the quality of the darker fiber has decreased
slightly. Breeders have been diligently working on breeding dark animals
with exceptional fiber, and much progress has been made in these areas
over the last 5-7 years (citation needed).
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.
Suri Alpaca
There are two types of alpaca: Huacaya (which produce a dense,
soft, crimpy sheep-like fiber), and the mop-like Suri (with silky
pencil-like locks, resembling dread-locks but not actually matted fibers).
Suris are prized for their longer and silkier fibers, and estimated to
make up between 19-20% of the Alpaca population. However, since its import
into the United States, the Suri is growing substantially in number and
color diversity. The Suri is thought to be rarer, possibly because it is
less hardy in the harsh South American mountain climates, as its fleece
offers less insulation against the cold. The Suri fleece parts along the
spine, exposing the animal to the cold, unlike the Huacaya fleece which
provides excellent cover over the backbone.
As with all fleece-producing animals, quality varies from
animal to animal, and some alpaca produce fiber which is less than ideal.
Fiber and conformation are the two most important factors in determining
an alpaca’s value.
Alpaca have been bred in South America for thousands of
years. Vicuñas were first domesticated and bred into alpacas by the
ancient Andean tribes of Peru, but also appeared in Chile and Bolivia. In
recent years alpacas have also been exported to other countries. In
countries such as the USA, Australia and New Zealand breeders shear their
animals annually, weigh the fleeces and test them for fineness. With the
resulting knowledge they are able to breed heavier-fleeced animals with
finer fiber. Fleece weights vary, with the top stud males reaching annual
shear weights up to 7 kg total fleece and 3 kg good quality fleece. The
discrepancy in weight is because an alpaca has guard hair which is often
removed before spinning.
Good quality alpaca fiber is approximately 24-29 µ in
diameter, and can sell for 2 to 4 dollars per ounce. Finer fleeces, ones
with a smaller diameter, are preferred, and thus are more expensive. As an
alpaca gets older the width of the fibers gets thicker, at between 1µm
and 5µm per year. This is often caused by over nutrition; if fed too much
nutritious food the animal doesn’t get fat, instead the fiber gets
thicker.
