2019 EPDs are now Posted Online!

The 2019 Expected Progeny Differences (EPDs) calculation is now available online. EPDs set AOA registered alpacas apart from others around the world, providing information that helps AOA members make breeding and buying decisions that support rapid and effective genetic gain!

Trait data that was submitted prior to September 2019 has been included in this calculation. This year’s analysis included observations for at least one trait on 36,956 Huacaya and 8,501 Suri animals. This translates to 73,348 huacayas and 16,213 suris for a total of 89,561 alpacas with EPDs.

Download the 2019 Producer Report by Dr. Enns for more information on this calculation. Be sure to download and archive your EPD report for 2019 (previous EPD calculations are not archived).

EPD Percentile Rank

Percentile ranks are calculated and displayed on the alpaca's EPD chart. Ranks are broken down by breed and gender. Special emphasis is given to traits that rank in the top 1%, 5%, 10%, 15%, and 25%. Searching is available by rank and by trait on the EPD search page.

Group Totals for Ranking

  • Huacaya Female (47,399)
  • Huacaya Male (25,949)
  • Suri Female (10,315)
  • Suri Male (5,898)

Alpacas that have had no trait data submitted, but are related to alpacas with data, may have EPDs recorded. EPDs are calculated up to four generations back from an alpaca with submitted data.

Plan ahead for the 2020 EPD calculation

Fiber testing can be done year-round, so now is the perfect time to submit your fleece samples that didn't make it in the 2019 calculation!

The Shear Report Instructions page provides the steps for submitting samples for testing. User entered traits — birth weight, weaning weight, birthing ease, and fleece weight — can be entered on each alpacas trait data page.
