Glossary of Alpaca Terms
If you are new to the alpaca lifestyle, you may not be familiar with all the terminology you hear from other owners, or read online. The more you know, the easier it is to navigate and improve your program. Welcome to the Alpaca Culture glossary. Terms touch on a sampling of many subjects central to the alpaca community: breeding, fiber, logistics, veterinary terms and genetics.
Aggregate breeding value: Also sometimes called net merit, this is the breeding value of an animal for a combination of traits.
Agistment: An arrangement in which alpaca owners board animals at a location other than their own property.

AOBA: Alpaca Owners and Breeders Association - North America’s largest Alpaca association.
ARI: Alpaca Registry, Inc. – The largest alpaca registry in North America. Membership is required to show animals at an AOBA event.
Apron: The section of fiber under the alpaca's neck and chest area. Fibers here vary in size and they may be coarse and medullated. Apron fiber should not be mixed with finer fiber.
Artificial insemination: Semen is collected from stud males and inserted fresh or frozen into females.
Backcrossing: (1) Mating a hybrid to a purebred of a parent breed or line. (b) Mating an individual (purebred or hybrid) to another animal (purebred or hybrid) when the two animals have one or more ancestral breeds or lines in common.
Bale: A variable sized sack, square, or package into which fiber is compressed.
Beater: A toothed or spiked metal roller that is part of a cleaning or opening machine used to process fiber into yarn.
Base population: The population of animals whose parents are either unknown or ignored for the purposes of inbreeding and relationship calculation. Typically, this term applies to the animals appearing at the back of the pedigrees of the original individuals in a herd.
Basic colors: Seven of the total twenty-two natural colors of alpaca. Black, white, light fawn, fawn, silver gray, brown and rose gray.

Biotechnology: Practicality married with scientific knowledge. Often refers to manipulating, locating, identifying or comparing genes. Also refers to reproductive technologies, for example artificial insemination.
Blanket: alpaca fleece of the highest quality, which starts at the shoulder, runs along the back and down each side and meets in the medullated belly fiber. Does not include belly, neck, leg, chest or britch. The image of a horse's saddle blanket is the origin of the term.

Burning: Removing vegetable matter from alpaca fiber during processing using chemicals.
BVD Bovine Viral Diarrhea: A cattle disease that has negatively affected the North American alpaca community since 2001. It is typically an acute (short term) illness that the healthy alpacas immune systems can eradicate. However, pregnant females that contract the virus will either abort the fetus, or if it lives it may be persistently infected with BVD and become a carrier of the virus.
