I received this response from AHA today. I give Mr Ward alot of credit for taking the time to respond to me. His response is on top and my initial inquiry is at the bottom.
John,
Thanks for the questions. Yes, the data from Amana has been put into the analysis and there were 11 other bulls in this cont. group. Some of the other bulls were fairly highly accurate. As I do a pedigree average, the only traits that seem a little lower than pedigree are the carcass traits. He may have performed a bit below average. This data would only give a significant affect to the bull himself and it must either be parents or other progeny that is affecting the sire. Please let me know if you have any further questions. Does not look like the two other progeny are in the analysis since there is no weaning or yearling information.
Best regards
Jack

Mr. Ward,
I sold this bull to a gentleman:
http://www.herfnet.com/online/cgi-bin/i ... 625&9=5D52
The epds on the bull show that he has had 15 calves with bw's collected in 2 herds, 13 for ww and yw in 1 herd, 2 for sc in 1 herd and 11 for carcass ultrasound data. But on my authorized user account, when I pull up the performance pedigree it shows only 2 head for all of the data. I know this bull was bred to some commercial cows and he was sent to the Amana colonies project. Are performance data from commercial cows being used in his genetic analysis for epd calculations? It appears that alot of weight has been placed on these calves of unknown background as it has really pulled down his and his sire's epds.
