Nick Harrington-Smith
Huacaya Halter, Suri Halter, Fleece, Performance
From a farming family and with agriculture running through his blood Nick has devoted much of his life to farming livestock. Nick began working with Alpacas in 1998 and currently co-owns and manages Alpaca Evolution, a herd of close to 800 alpacas situated in the beautiful Buckinghamshire countryside.
Nick’s time in Alpacas has presented him with a great deal of opportunities. Nick has been involved in the selection and purchase of breeding stock in both North and South America and Australia, giving him the opportunity to assess many thousands of alpacas in the process. A dream come true! He has also watched with pride as those alpacas have gone on to become cornerstones of the UK and European breeding herd. In part, these opportunities encouraged Nick to enter the first British Judge training scheme and becoming the first graduate of the scheme in 2003 and he is now a certified judge trainer for the British Alpaca Society. Nick then went on to become the first European to have gained qualification as an AoA (American) Halter Judge, as well as certifying for Fleece Judging and Performance classes.
Nick has judged shows across the UK, Europe, Canada, Australia, and the USA and considers each show judged a great privilege. The high points in his career have to be judging the American National Show and the American Futurity, there can be no greater reward for a judge than being afforded shows of such standing. Nick strongly believes showing is about education delivered through informed and accurate oral reasons. He is a very strong believer in the show ring as a promotional vehicle for alpacas, but also has a real awareness of the need to keep in perspective its importance in respect of breeding decisions. Nicks primary objective when judging is to ensure that all exhibitors experience an enjoyable and informative event.
Nick is married to wife Terry and enjoys nothing more than time spent enjoying the alpacas and introducing his much-loved grandchildren to the joys of farming, alpacas, and the Great British countryside. Though a spot of fishing doesn’t go amiss now and again!

Tim Hey
Judge
I grew up in Australia on my family farm and in 1994 we purchased our first of our breeding stock. In 2002 I moved to the United Kingdom to manage a leading herd of white huacayas called Alpacas of Wessex and in 2006 my wife and I started Inca Alpaca.
I have judged the British Alpaca Society (BAS) show three times and in 2015 I was invited to judge the 25th anniversary Australian Alpaca Association National Show with the late Karen Caldwell. I have consulted on alpaca selection and breeding in China and has been in Peru twice learning from some special breeders and selecting stock for the UK market. I am also BAS judge tutor and get involved in organising my local halter and fleece show.

Amanda VandenBosch
Judge
Amanda VandenBosch has been raising alpacas, both huacaya and suris for 32 + years along with her family at Flying Dutchman Alpacas, LLC in Bend, Oregon, USA.
Amanda travels worldwide as an International Alpaca Judge, judging and teaching on all aspects of alpacas, fiber & end product. She has been active with many organizations and is co-author of “Art & Science of Alpaca Judging” and “Innovative Fleece Assessment Judging System” along with many research projects related to selection, health and wellbeing of the alpaca.
Proud co-hosts of 15th Annual Education with a Destination Event and Stanford Livestock International, Ltd export services complimented with alpaca retail store Alpaca by Design. Amanda is passionately involved with non-profit organization Quechua Benefit in Peru.
Amanda is an alpaca enthusiast in all apects from selective breeding decisions and raising of high quality alpacas to a passionate educator known for her interactive clinics and sharing of knowledge with fellow alpaca enthusiasts worldwide.

Color genetics of alpacas
The lecture, entailing examples and pictures, is aimed at breeders who either already have experience with color genetics or who would like to get an initial idea of how color genetics can be used for breeding programs.
Despite targeted mating based on color genotypes, surprising and sometimes puzzling results still occur. Thus, color genetics is more than the color genotype and the calculation of offspring. Even genetically black alpacas can appear brown to fawn and alpacas that appear white can be genetically homozygotic black.
Why is that?
The two-part lecture provides answers and shows approaches that can be used directly in your own breeding program.
Part 1 – from Vicuna to “Ideal Alpaca”
A genetic journey back to the beginning gives an idea
- how early color mutations contributed to shape today’s ideal type of alpacas,
- about the significance of a fading color across the body,
- why identical color genotypes show different fleece colors and what this means for breeding.
Part 2 – Color Patterns
Color patterns are genetically completely different from the base coat colors. They can dilute or darken the base coat color; they can create spots or white areas with different patterns.
This has led to descriptions such as Modern Grey, Pintaloosa, Appaloosa, Harlequin, Leopard, Classic, etc. But what is actually behind these terms and how does one differ from the other?
Here too, a look back to the beginning shows
- where color patterns originate,
- how we can specifically breed with them,
- what risks need to be taken into account when breeding with color patterns.

Presentation of the breeding quality assessment of the AZVD
The breeding suitability test (ZEP) is an objective method to evaluate an alpaca in three areas: 1. phenotypic evaluation, 2. health evaluation and 3. fiber quality evaluation.
The ZEP assesses the alpaca on the day of the examination and cannot make any statements about possible changes that only occur over time.
The aim of the ZEP is to classify animals into categories that assess their individual suitability as breeding animals:
- Category A is fully suitable for breeding
- Category B is conditionally suitable for breeding
- Category C not suitable for breeding (hobby animal)
31 phenotypic, 23 health-relevant and 21 fiber properties are tested and evaluated taking age into account.
The testing team basically consists of two phenotype testers and a veterinarian.
The following advantages arise for breeders and buyers:
- standardized testing procedure by qualified examiners
- defined catalog of criteria according to scientific criteria
- Recording all deviations from the alpaca standard
- veterinary examination for hereditary diseases and genetic defects
- Fiber analysis with OFDA 2000
- Certified quality control with results report on site
- direct breeding value estimation
- Reliability when breeding, buying and selling
- independent assessment basis for reports
Every alpaca presented at ZEP must be registered using DNA and have a working chip.
