BIF adjustment factors by breed

http://www.beefimprovement.org/PDFs/Home/2011/2011-ABEPD-press-release-1.pdf

maines

bw up
weaning weight down
yearling weight down
rib eye area up
marbling way down

even herefords have a higher marbling score.  seems like work to do. i will try and find which sires were used.  probably something ali based.

Don't know if MARC publishes the sires they use, you may have to call and ask.  AMAA should know.  However, the adjustments account for the sires' EPDs in their breed evaluation.  So if a "bad" bull gets used at MARC (high BW, low marb, etc.), that doesn't hurt the breed unless his EPDs (in his breed evaluation) aren't appropriately bad.  I don't follow Maines, so I don't know how the bull you mentioned ranks within his breed.

PM me if you want to discuss this.
