[QUOTE="smnherf, post: 693867, member: 3235"] I realize exactly what I am saying. I use the data available. I prefer actuall kill data, but if that isn't available, ultrasound data is usefull if their is enough data collected in several herds. My overall question though is how often does ultrasound miss with respect to IMF? The calves were all born from about Mar 10th to May 10th. The 0232's would tend to be about 30 days older as I breed my heifers to calve earlier than my cows. Backfat on 0232's would be .51 ave and ave bf on boulder would have been .45 with 4 of the five being Select yg 2's. 1 of 0232's select was a YG 2 also. They were all weaned, backgrounded and finished in the same contemporary group though. [/QUOTE]
