WebIndividual Traits. U.S. evaluations measure genetic variation for 50 unique traits important to dairy producers. Nearly all U.S. traits are calculated and published by the Council on Dairy Cattle Breeding (CDCB). Most U.S. traits are expressed as Predicted Transmitting Abilities, or PTAs, that measure the predicted difference of an animal’s ...
