Following is a note I got from Cornell. The web site at UC Davis has some GREAT articles:
I have reviewed the material on the National Beef Cattle Evaluation Consortium (NBCEC) website, http://www.nbcec.org/nbcec/index.html. The NBCEC does not recommend the use of DNA markers that have not been independently validated. From the NBCEC website the following traits have been independently validated for Igenity and Bovigen:
Trait Igenity Bovigen
Tenderness y y
Quality grade y y
Marbling y y
Backfat y n
Ribeye area y n
Yield Grade y n
ADG y n
While these companies make claims for feed efficiency, maternal traits and docility, these have not been independently validated, therefore I would not have confidence in their claims until that is done. From the data NBCEC provides, Igenity does offer more independently validated traits.
Attached is a good article by Dr. Alison Van Eenennaam, UC Davis on DNA Markers. I will edit this into a shorter article to send to producers.
For those of you with a high speed Internet connection, http://animalscience.ucdavis.edu/animal ... /index.htm has the NCBA "Cattlemen to Cattlemen" episode on DNA Markers.
I have copied Dr. Pollak on this email. He may have other comments/clarifications to make.
