Makin' Fiber

Alpacas are bred each year because their fiber is finer when they're pregnant or nursing.
The other reason the females are bred each year is because they're so darned valuable. That was a big eye-opener for me. There  is an alpaca stud named Cantano of Peru who is valued at $250,000.00. Ann told me that prices for alpacas have come down in recent years, and a pregnant female of high quality can be bought for around $20,000.00, down from perhaps $25,000.00 a year ago. It's all about the fiber, folks. Cantano is the winningest alpaca in America, for the luster, fineness, and density of his fleece. Although a research paper published by the Agricultural Issues Center of the University of California in 2005 examined the US alpaca industry and concluded thus: Current prices for alpaca stock are not supportable by market fundamentals; the industry represents the latest in the rich history of speculative bubbles.

Yeeks. I hope not to be around to hear the alpaca crash. The dot-com crash was deafening enough. And that's their opinion, those Californians. We're in Ohio.

Alpaca breeding, ideally, is carefully controlled, to give crias with the finest fiber. A female cria can be bought for about $5,000. The price goes up as the cria gets older. Ann told me that people can buy alpacas affordably if they have the patience to mature them, but it's anything but a "get rich quick" proposition. And an alpaca's value changes every month as it matures or puts progeny on the ground. Understandably, there is a lot of bartering and trading going on the in alpaca world, which probably helps explain why it's such a close-knit (pun intended) community. 

 Last summer, one of the Riverboat studs opened a gate--actually dismantled it--and all the males got in with all the females.We helped, didn't we, girls?

From this one saturnalia, four alpacas came away with unplanned pregnancies; fifteen of the females are pregnant right now. Oh, I'm wiggling with delight at the prospect of having 15 new crias to photograph! They're like liquid-eyed fawns from outer space, wearing tiny toe shoes. Since alpacas gestate for 11.5 months,  most of the crias are due in June (the orgling orgy took place in July 2007).
Crias nurse for about six months on average, though Annie and Charlie like to let the female alpaca decide when to wean her cria. This overgrown cria wasn't quite getting the message from its increasingly irritated mama.
Alpacas don't have a heat period like most animals; ovulation is stimulated by the act of mating, as it is in birds. They tend not to mature until age 2-3. Online, I found details about the male alpaca's wedding tackle that I noted with interest. It's extremely long, thin and prehensile. Ooo. Gotta navigate all that fluffy stuff, I reckon.White alpaca: Did your readers really need to know that?
Zick: PreHENsile??
Alpaca: So I expect we'll be seeing you in July.
Zick: Bet on it. I wanna learn how to orgle.

THIS JUST IN! Click here to hear an alpaca orgling!

If you listen to it for awhile, it is kind of sexy, in a Bogartesque way. Well, maybe a little more Peter Lorre than Bogart. Agggh!

How gorgeous is this gal, with her lustrous dreadlocks? The alpacas in these shots have been shorn at different times, so some of them look all grown in, while others have shorter fleece. They're shorn once a year, but obviously, not all at the same time. More alpacas tomorrow. But no more prattle about speculative bubbles.

All About Alpacas

Alpacas (Vicugna pacos) are domesticated animals descended from (or more correctly, developed from) vicunas, which are gracile, delicate wild camelids. For those Spanish speakers, I apologize; I cannot figure out how to get the little squiggly line to float over the n in vicuna. I'm going to try again. Vicu&ntilde. Vicu˜na. Vicu˜a.Vicun˜a.Vicu˜n˜a. Argggh. Know that I mean to... This smallest of the camelids was hunted nearly to extinction for its valuable fleece. Incas rounded up wild vicunas and sheared them, then released them, but in modern times people found it more convenient to shoot them, and reduced their numbers to 6,000 in the wild by 1960. Peru and Chile moved to protect them by establishing parks, and today there are about 125,000 vicunas in the wild. They are classified as threatened. And, in my book, adorable. ~Vicuna, northwest Argentina. Photo by Nick Athanas, www.tropicalbirding.com

This alpaca looks a lot like a wild vicuna in coloration. I'd love to have her waistline.

Though they're sometimes confused with llamas, alpacas are much smaller (about 3' at the shoulder) and lighter of build. There are no wild alpacas; they have been bred as domestic animals for thousands of years. Their fiber is much finer than that of llamas or sheep, for that matter. Ann, proprietress of Riverboat Alpacas, explained to me that all alpaca and sheep fiber has little scales that stick up off of it. It's those scales that give us the perception of scratchiness. The scale height (the amount it sticks up off the fiber shaft) determines its scratchiness. Wool scales stick up .08 microns off the shaft. Alpaca scales stick up only .04 microns. And a micron is 1/25,000 of an inch.

The higher those scales stick up off the fiber, the scratchier the fiber. But the more closely those scales are packed, the smoother the fiber feels. Mohair wool has 6-8 scales per 100-micron length, while alpaca fiber has more than 9 scales per 100-micron length.

Another determining factor in the fineness of the fiber is the mean diameter of a sample of fibers. Again, this diameter is measured in microns. Let's start with human hair, which is between 40-80 microns in diameter, sometimes as high as 100 microns. Strong fiber, as is found in Navajo wool rugs, is 30 or more microns in diameter. You do not want to wear a fiber that coarse. Hair shirt, and all that. A medium fiber is from 25-29.9 microns in diameter. Fine fiber is 10-24.9 microns. Superfine/Baby alpaca fiber is 18-20 microns. And Royal fiber is less than 18 microns in diameter. So really good alpaca fiber is very thin, and has lots of very low-profile scales sticking up off it. It's also strangely and delightfully lustrous, even shiny.

And I'm sorry, but I don't want wool against my skin at all. But alpaca...now, that's another story. Alpaca fleece, besides being light and floaty and incredibly warm (3-4 times warmer than wool!) is virtually lanolin-free, which means it's hypoallergenic. The first thing I did while shopping was bury my nose in the fabulous alpaca teddy bear's fur and wait to see if it bothered me. Nope. I can't say the same about wool or rabbit fur.

The alpacas on Riverboat Ranch are almost all suri's. This is a variety of alpaca with long, silky hair with a high sheen. They have one gelded male who is of the huacaya variety. Their fleece is crimped, like a sheep's, and stands up in a thick, lush pile.

Because suri fiber is of higher quality, alpaca breeders don't intentionally breed suris and huacayas together. (Which is why Riverboat's lone huacaya male is gelded.) Suris are rare in Peru, and it's thought that they might suffer more from the cold there, because their silky hair does not offer as good insulation as does the fluffier huacayas'. They are rapidly gaining popularity in the US, however, and breeders are concentrating on expanding the range of colors in the suri line. In Peru, breeders prefer white animals, because they dye most of their fleece. In the States, people favor natural-colored blankets, hats, scarves and sweaters, so there's heavier selection for beautiful natural fleece colors. Check out this incredible autumn auburn. Look at the sheen on that hair! I don't think Annie uses Pantene "Liso y Sedoso" conditioner on her alpacas, but you'd think so. I'd like to get a shot of my Phoebe standing next to this beauty. Alpaca fanciers refer to this kind of fleece as "greasy." Gotta love it.

Desperado, one of Ann and Charlie's first-acquired alpacas, is a black herd sire. They have a gorgeous maroon female, some caramel colored ones, mahogany, and, through breeding to a gray sire called Gunsmoke, they're shooting for a gray this coming spring.

Ann and Charlie's best alpaca is Sir Wilfred, an Accoyo suri, named for a Peruvian ranch where line breeding (breeding granddaughters to grandfathers and the like) developed animals with exceptionally fine fiber and what alpaca ranchers refer to as "good coverage," meaning lots of fiber all over the body, even the legs. There's deeply wrinkled skin under that hair, which means, I'm guessing, that there's more surface area for fleece to grow on. I saw one alpaca whose legs had been shorn, and was amazed at its deeply corrugated skin. I didn't photograph it, thinking it might have been a problem, but further reading told me alpaca breeders want them wrinkly! I'll have to go back and try to get a shot of that.This is Sir Wilfred, the Accoyo suri stud. (There are also Accoyo huacayas). If I'm not mistaken, that chestnut animal in the background is a huacaya. See how wooly he looks, in comparison to the silky suri in the foreground? Want to breed your female alpaca to noble Sir Wilfred? Got $1500 lying around?

One really interesting aspect of alpaca biology is that their fleece gets thicker in diameter each year, as they age. Thinner fleece: better, softer. Thicker, not as desirable. Alpacas can live to 20; the oldest known, Vomiting Violet, died at 29 on her ranch in New Zealand. Pregnant females have finer fiber than ones which aren't pregnant, so alpacas are bred each year. I remember my best hair days happened when I was pregnant, too.
Wonder how many ounces of fiber this gal is carrying? Hope she's got a cria (baby alpaca) in there, too! So: Are you in love with alpacas yet? I am!
