Limousin and Lim-Flex® breeders have embraced DNA testing as a tool in genetic evaluation and selection. GeneSeek®, a Neogen® company, is currently NALF’s official DNA lab testing partner.

For questions or more information regarding DNA testing, please contact Alison Jones, NALF director of DNA processing & accounting operations, at 303-220-1693, ext. 59, or

Please allow 3-4 weeks for DNA test results.

Ordering DNA Supplies on DigitalBeef

Cyber Campfire on DNA Testing via the Member Site – Brittany Barrick covers ordering and the display of DNA  results in Digital Beef along with new tests and the future of DNA testing.


Genomic EPDs

NALF launched genomic-enhanced EPDs in the fall of 2015, providing GE-EPDs for all Limousin and Lim-Flex animals that have completed DNA testing for genomic profiles.

The advantage to animals with GE-EPDs is increased EPD accuracy values on many traits equivalent to having 8-20 progeny. This adds greatly to the predictability in selection for genetic merit of young, unproven seedstock. Animals that are genomic-enhanced will have the NALF GE-EPDs displayed on their animal detail screen and performance reports in the NALF-DigitalBeef platform. Traits that are genomic-enhanced are highlighted in yellow on these reports.
