[QUOTE="alexfarms, post: 627515, member: 8677"] How much performance did I actually lose from inbreeding depression? That is the questions that I don't think anyone knows the answers to, and that is why inbreeding isn't factored into the genetic analysis for epd calculations. It is obvious that it exits, but tough to put a number on. I try to select for total performance in my inbreds. I have had this line since late 2001 and my results have been pretty humbling compared to the previous owners of the line, it appears to me. They went more for growth and carcass and less for maternal traits than I have. I place fertility first, because I think it is so important for the sustainability of a line and that probably has hurt the growth performance of the cattle I have been producing from the line. There is lots of semen on growth bulls in this line and I will contiune to keep trying to find ways to work them in without getting big increases in birth weights and loss of maternal traits. The line gets compared to outcross cattle through the use of bulls on outcross cows and that helps to develop their accross breed epds. [/QUOTE]
