Ultrasound data

Can someone tell me what the average is of Ultrasound Data? (IMF, Rib eye, Rump Fat, Rib Fat)  I had some heifers scanned and I am trying to interpret the data.

All depends on breed, age, etc. Are you looking at adjusted or actual numbers?

I am looking at data for yearling Angus heifers.  I have access to both Actural and adjusted numbers.  The one that I think did pretty good is my show heifer this year.  She had a 6.47 actual IMF, 12.1 Rib eye, .46 rib fat, and .54 rump fat.  She scanned the best out of all of my heifers.  This heifer was 2nd out of 9 at the Illinois beef expo.

|I'm not sure you can compare data between management groups. For instance...if you have a bull calf that is fed alot of corn and fancy feed all his young life and do a IMF of 4.5. Then if you took the same bull calf,no creep, weaned on not much,no corn, he might IMF 3. Thats just a guess. I learned of one commercial cowcalf operation using Angus Genetics that feed baby calves whole corn in creep feeders and weaned them early,feed corn hard(back when it was cheap) and hit some ungodly mark in the U.S. premium beef and certified Angus beef deal. This was when corn was 2$ a bushel though. Very interesting topic.

the keyword to look up is contemporary groups.

We didn't ultrasound this year cause we did not push our bulls at all , there yearling weights  were not big so Iwas pretty sure it would not pay to ultrasound , if you want to get your maximum weight, highest  INTRAMUSCULAR, ribeye , an then no one really cares about the fat to much, one of the Champion carloads in Denver averaged .50 on the fat an proably wasn't a year old. Your show heifer is very good evidence of this .

Well as far as the contemporary group goes she blew everything else out of the water.  She actually gets less feed than our replacements.  We showed her momma and all she got was protein her last two months of the show season.  They are the really hard keeping kind...they get grouchy when they don't get to eat much.
