Yocom-McColl is working on a grant from the Alpaca Research Foundation. This project requires samples taken from ARI registered alpaca huacayas. The title of the project is: Using Objective Measurement to Identify Superior Characteristics of the U.S. Alpaca to Assist in Making Long Term Breeding Decisions.
COLLABORATORS FOR THIS GRANT
The final statistical report will be completed one year after the last sample is received at Yocom-McColl Testing Lab in Denver. Breeders involved in this project will be mailed only their own individual test results and the complete data analysis will be reported to the Alpaca Research Foundation. Individual samples will be identified by chronological number in the study and each sample's origin will remain confidential. A technical article suitable for publication in the Alpaca Registry Journal, and/or other acceptable technical publications, will be prepared by the research team.
DESCRIPTION OF PROJECT
Six hundred alpaca huacaya samples must be obtained in one shearing season.
There will be eight categories, 67 samples in each category, identified as males and females, one year, two years, three years, and four years of age or older (plus or minus two months on shearing date and age of animal).
In addition, we need 67 castrated males (geldings) from across the country and these animals must be three years or older in age. Testing the fiber from castrated males gives information about fiber production without the influence of male hormones.
Fibers will be measured for average fiber diameter, lab scoured yield, staple length, medullation and color*, staple strength, position of break, resistance to compression, and fiber curvature. (*Medullation and color tests can be performed on white or light fiber only.) The value of this testing is $50.00 per sample. There is NO cost to project participants other than the packaging and shipping of ARF grant fiber samples to Yocom-McColl in Denver, CO.
The amount of sample required for all tests will be an area 6" x 3". The sample must be in a moisture proof sealed freezer bag (Ziploc brand bags in the gallon size - 10-9/16" x 11") and retained in the staple configuration (as it grows naturally from the skin outward on the animal). Our ARF Project Sampling Form can be filled in on screen and then printed out to be mailed with the sample.
Note: Insufficient sample size or incomplete information on the ARF Project Form cannot be included in this study. We need the full 6" x 3" sample size in order to accurately complete the tests we have committed to study in this grant. No samples will be returned.
This project is designed to include a range of geographical areas and in order to accomplish this goal, we need to obtain a percentage of samples from each area based on the U.S. population of ARI registered alpaca huacayas.
SAMPLE REQUESTS BY REGION
We are asking you for a pre-commitment of samples at your earliest convenience (prior to shearing) from these six geographical areas: Northeast, Southeast, Great Lakes, Central, Rocky Mountain, and West Coast. Sample requests have been determined based on the number of animals represented in these regions.
A set of samples reflects eight (8) individual animals: one sample from each male and female alpaca in the one, two, three, four year old or older age categories.
NORTHEAST: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont.
SOUTHEAST: Alabama, Florida. Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia.
GREAT LAKES: Illinois, Indiana, Michigan, Ohio, and Wisconsin.
CENTRAL: Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma, South Dakota, and Texas.
ROCKY MOUNTAIN: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming.
WEST COAST: Alaska, California, Oregon, and Washington.
Each 6" x 3" Alpaca Huacaya fiber sample should be taken from the mid-blanket area, packaged in an airtight freezer bag with a completed ARF Objective Measurement Study sampling form placed in a readable position, and then shipped in a cardboard box to protect the accuracy of the yield test.
We need pre-commitment from the six regional areas and a running count will be posted on our web site on this page. These sample commitments will be acquired on a first come basis.
It is imperative that the sample size and information follow our stated requirements so that we can have a meaningful statistical analysis for this project. No samples will be returned because of inadequate size or information. We appreciate your interest and support of our work on this grant.
Our ARF Project Sampling Form can be filled in on screen and printed out to be mailed with the sample.
