Alpaca Fiber: Color Contamination
Author: mike safley
Alpacas come in many colors; on occasion, too many colors.
Dark-colored fleeces with the occasional light-colored fiber spread
throughout the blanket have one color too many. White fleeces, with the
odd fawn or black fiber hidden among the white ones, are equally at
fault. The subject of color definitions, roan, grey, and multies is a
hot potato tossed between the show rules committee, judges, the AOBA
Board, show management, and exhibitors. If alpaca breeders do not
discriminate against solid colored alpacas with the occasional
off-color fiber in their fleece, the problem could haunt them for
sometime. In my opinion males that lack uniformly colored fleeces
should not be herdsires.
I judged the 2005 MAPACA Show with Jude
Anderson and Julio Sumar. My apprentice was on the microphone doing
oral reasons, and when he finished, the show superintendent Peg
Stephens gave a stern wave, signaling me to her desk. As I approached,
she handed me a cell phone, which was a surprise - I had never
been summoned to the telephone in the middle of a show. Your apprentice
just used the "C" word, a voice at the other end of the line intoned.
It seems an exhibitor phoned an AOBA official, not in attendance, to
report my apprentice for using the words color contamination in his
oral reasons for class placement. The AOBA official instructed me to
gather my fellow judges and their apprentices to inform them that the
use of the word contamination, referring to color in oral reasons, is
against show division policy. The acceptable term is lacking color
uniformity. Does this policy take political correctness, or should I
say color-correctness, too far?
Alpaca color is an extremely important textile trait, and it has
been confused by constant changes in our show rules. In the beginning,
the show rules color chart designated the 21 natural alpaca colors used
by the international textile trade. There have been multiple changes in
the original color designations, and several of the color classes were
deleted in their entirety. Among those eliminated were streaky white
black, streaky white fawn, intermediate grey and streaky light coffees.
Not only were these colors important as textile designations, but also
as selection markers. The failure to acknowledge these colors in
properly designated classes is potentially disastrous to the future
breeding value of our national herd.
The current show rules make small work of the color uniformity issue. The total of what they have to say is set out below:
C.
Negative traits for unshorn Huacaya [Suri] Fleece. (The categorization
of minor, major, and serious faults shall be assessed by the Judge
according to the degree of fault present.) 5. Lack of consistency of
fineness, staple length, character, color, and density. (Page 118 -
2005 AOBA Show Division Handbook).
The judge has wide latitude when construing the fault. I expect the subject to attract considerable attention in 2006.
On a recent trip to Peru, I asked Carlos Montavalo, the central
manager of fiber processing at Inca Tops, in Arequipa, Peru, what
breeders could do to improve the value of their fiber production. He
said, They could reduce color contamination. By that I mean eliminate
dark fiber in light fleeces and light fiber in dark fleeces. He went on
to tell me that if a customer such as Ralph Lauren (Polo) found more
than four or five dark fibers in a 45-pound bolt of fabric, they would
return the cloth. But worse yet, if they found these fibers in a
finished garment, they would claim the total costs incurred for all of
the garments made from that cloth. These charges often exceed the price
of the fabric that we sold them, he said, and that is a disaster.
Montavalo finished by saying, We spend millions of dollars each year
for labor to extract dark fibers from light colored cloth. I also spoke
with Alonso Burgos about the color contamination problem, and he
pointed out another pitfall. When a customer for white tops, perhaps a
Chinese client, takes possession of an order, the lot is immediately
inspected to see if even 1 or 2 dark fibers are present. If any are
found, a call is made and a price discount is requested. If the seller
refuses the discount, the client says, come get the order. Alonso
points out that this negotiation usually ends with the seller bowing to
the east.
There is another cost associated with color
contaminated fiber: keeping the scouring train and combs free of
off-colored fiber. Once a white fleece containing dark hairs is
scoured, the entire production line must be shut down to remove any
offending color impurities. A blow torch is fired up, burning away any
remaining fiber from the equipment: a costly process. Dr Julio Sumar
recently told me that he has studied the average micron counts for each
of the colors found on multicolored alpacas. He discovered that there
is often a significant difference between the two. This is an
additional consequence of contaminated fleece - variability in
micron counts which coarsens the handle of finished garments. Dark
fibers in white fleeces are often guard hairs, and guard hairs, as we
all know, are one of the most negative of all fleece traits.
If
you need more proof about the evils of color contamination here is what
Jude Anderson has to say about the current status in the Merino Sheep
industry in Australia. There's a fiber market assurance program called
Clip Care, which among other things requires farmers to totally clean
their shearing shed before and after shearing, to cull anything with
any color other than white, and not to allow any colored animals on the
property. The Australians take the idea of color purity as seriously as
any fiber breeders in the world as Jude points out when she says, We've
had sheep farmers buying fox guard alpacas from us that absolutely will
not take any other color than white. They said they don't want the
sheep getting contamination from colored alpacas by rubbing up against
them in the paddocks and getting a colored fiber mix up, or if colored
alpacas rub themselves on fences, the sheep can come along behind them
and become contaminated. Call it anal, call it paranoia, but that's the
real world!, says Jude.
I was recently invited by Alonso to accompany him and Dr. Rito
Huayta on a trip to Julio Barreda's Accoyo. They intended to purchase
several males for the Pacomarka breeding program. I leaned against the
rock wall of the corral as Barreda herded 20 beautiful Accoyo males
into the catch pen for Alonso's review. My eye immediately found an
exquisite male, big and bold, with ideal phenotype. I fell in love. As
Alonso worked his way down the line of males, coming closer to the
object of my affection, he would eliminate any animal that did not meet
his exacting standards. I smiled as he laid his hands on my first place
male and was shocked to see him signal this beauty out of the corral.
As the cowboy dragged the rejected macho past me, I asked if I could
inspect him. The fleece was dense, fine, and wonderfully crimpy. I was
puzzled. Alonso finished his selection, and we walked down the hill to
Don Julio's home, I asked why he had culled such a beautiful male. It
had a few dark fibers in the fleece, he said. I excused myself;
huffing and puffing I made my way to the top corral to re-inspect the
reject. Looking very closely, I soon detected the offending foreign
fibers, the fawn ones, that I had previously missed; one about every 6
inches.
As Alonso and I made our way back to Macusani, he
explained that he has made every effort to eliminate color
contamination from the breeding herd at Pacomarka: both white and
colored alpacas. I learned a valuable lesson that day. I won't soon
forget to test my aging eyes in identifying this defect.
The AOBA Board of Directors, acting on input from their members, the
Show Rule Committee, and the Judge's Advisory Committee, has made an
important revision in the color classification rules for 2006 fleece
and halter shows. The rule change reads:
Part VI. Section 1.B.
5.e and f. (Page 50) Creation of two new colors and deletion of roan
(Global including Appendix XIX). Purpose: A handbook global change that
clarifies the confusion that exists with regard to dark and light
alpacas that do not fit into the solid color classes or grey classes.
Creates more inclusive show environment for exhibitors and their light
and dark alpacas that clearly do not fit the solid color or grey color
definitions. e. Indefinite Light: White or Beige alpacas/fleece with
significant dark fibers uniformly interspersed throughout the blanket.
f. Indefinite Dark: Colored alpacas/fleece with significant white/light
fibers uniformly interspersed throughout the blanket. Alpacas with two
colors in their fleece will hereafter be classified as indefinite light
or dark. Eliminating the roan classification is a very significant
improvement in the show rules that will make life easier for color
checkers, exhibitors and judges. The new rules tell us that animals
with significant off-color fibers will be placed in indefinite classes.
I suspect that, over time, animals in these new indefinite color
classes will be used in grey breeding programs. Solid color classes
will be made up of alpacas that have either no off-color fibers or only
the occasional off-color fiber in their blankets. The new rule for
solid color classes states: PART VI. COLOR RULES
Section 1. Color Definitions
B.1.
Solid Color alpacas shall be defined as animals with solid color
blankets and may have minimal, not easily recognizable, secondary color
contamination regardless of the color on the head and extremities.
[Emphasis in original] Personally, I would hold to an even higher
standard; that alpacas with any off-color fiber belong to the
indefinite color classes. I submit that the benchmark should be zero
tolerance for color contamination in solid classes. The new rules state
that alpacas with minimal off-color fiber, competing in solid color
classes will be regarded as lacking color uniformity. These animals,
all things being equal, will not fare well against entries that have
truly solid or one-color fleeces.
The next step in the process
of refining our industry selection criteria will be a new appreciation
by breeders that selecting solid-colored alpacas with color uniformity
is critical. It is my hope that, as this awareness is incorporated into
selection decisions, a potential problem for our national herd will be
eliminated.
