[QUOTE="novaman, post: 706971, member: 2744"] This past January the dairy breeds began using genomic evaluations to enhance the accuracies of the current proofs. The animals with high accuracies gained very little from these DNA tests. The group that benefited the most is the young, unproven sires. Most of the young sires I saw were at 70% accuracy w/o having any offspring born. Granted 70% is quite low but I was impressed it could be that high off the bat. It will take until the spring of 2011 before we start getting any hard data back on these breedings to see just how things worked out. It's very exciting to see such advances in the way we evaluate the genetic merit of young animals. [/QUOTE]
