Top Ranked Alpaca Herdsire!

FG Powergrid

We just received notice that our herdsire FG Powergrid ranked First in one of the Alpaca Registry’s Expected Progeny Difference (EPD) traits related to his ability to pass on his incredibly consistent fiber to his offspring.  Read on for more information about the EPD program and how we are using this information to enhance our breeding program at Peaceful Heart Alpacas.  (You can see the text of the letter we received below.)

Breeding decisions are one of the most important ones we make as alpaca farmers.  Our goal is always to produce improved fiber characteristics with each new generation.  So, we look carefully at the fiber of each of our females, and evaluate her strengths and areas that we would like to improve.  From there, we choose the male that will most likely improve her weak areas without losing the positive characteristics she has.

We evaluate our alpacas in a number of ways, including a hands on assessment and scientific analysis of their fiber.  Each year at shearing time, we take a sample from the fleece of our alpacas.  This sample comes from the midside of the alpaca, and is sent to Yocum-McColl fiber testing lab where it is assessed for a number of traits important to alpaca breeders, including: fineness, measured as Average Fiber Diameter; consistency of the fiber diameter across the sample, measured as Standard Deviation; Comfort Factor, measured by the number of fibers under 30 microns in diameter (fibers above this will ‘prickle’ skin when in a yarn) and several other factors.  We also weigh the amount sheared each year and submit that fleece weight information as well.

From that analysis, we receive a histogram for each alpaca detailing their fiber statistics.  That report is also sent on to the Alpaca Registry (ARI) who yearly use this data from alpaca farmers across the country to generate EPDs.  EPDs are used in many livestock industries to guide breeding decisions.  They help us by giving a numerical value to show which alpacas are most likely to pass on specific fiber characteristics.  We have found that the data we are receiving mirrors our personal observations over the last 7 years we have been raising alpacas.  Powergrid is a great example.  He ranks in the top 5% in all EPDs related to fiber fineness, and is number 1 in the measurement for consistency (standard deviation of average fiber diameter).

Powergrid has been the foundation of our breeding program at Peaceful Heart Alpacas.  He was one of the first alpacas we bought, and has produced 11 crias for us.  We have seen the similarity in fleece structure with the birth and growth of each cria.  Multiple crias have followed in his steps to win blue ribbons for their fleece, as he continues to do.  You can learn more about Powergrid on his webpage.  We are also offering (until 3/31/13) a special package of two girls bred to Powergrid for spring 2013 crias, with additional breedings to Powergrid or any of Peaceful Heart Alpacas’ herdsires.

If you are interested in learning more about histograms and EPDs and how these tools can be used to improve your alpaca breeding program, we will be offering a class focusing on alpaca fiber and health on June 1.


We received a letter today (Feb 26) from the Alpaca Registry, signed by the executive director Darby Vannier,  that I am proud to share:

“I am writing you because we would like to feature your alpaca in a Top 5 list of EPD traits during the AOBA National Conference and Show taking place in Denver, May 16-19, 2013.  Alpacas were ranked according to breed and gender.  Only alpacas with a trait accuracy greater than or equal to .1 were ranked.  We would be proud to list your alpacas’s EPDs along with information about your farm, but we need your assistance to do it.  This information will be featured in a looped presentation on a monitor at the ARI booth.  Time is of the essence and we need to hear from you as soon as possible.

Alpaca: FG Powergrid; Trait: SDAFD; Value: -0.843; Accuracy: 0.515; Rank: 1

The presentation will include a picture of the alpaca along with its EPD statistics and ranking.  Your farm name and contact information will also be displayed.

If you consent to display your alpaca at nationals, please complete and sign the following form and mail to ARI in the enclosed self-addressed stamped envelope.

We are also requesting a photo of your alpaca to be included in the presentation.”
