[QUOTE="UG, post: 1349460, member: 714"] First of all I want to provide a disclaimer that I haven't spent a lot of time studying RADG and DMI. I also haven't seen much from AAA in recent years regarding these two traits, and if the EPDs are accurately predicting feed efficiency and feed intake in cattle. That being said, following are my thoughts. RADG: If I understand the trait correctly, a higher score indicates greater average daily gain on the same amount of feed. So, as long as I can keep the size of my cows at an acceptable frame score, I want as much RADG as possible. It would be interesting to see if there is much of a correlation between RADG and frame score. DMI: In a perfect world I want my cows to have low DMI and my feeder cattle to have high DMI. But, we can't make high DMI calves from low DMI cows. So, if I was putting much selection pressure on DMI, I think I would aim for moderate DMI scores. [/QUOTE]
