[QUOTE="giftedcowboy, post: 640841, member: 10219"] I have witnessed too many way to manipulate EPD's . If you go back and read through the works of Dr Willham in his development of EPD's you will have a greater understanding. The EPD's are only as good as the data presented and only as good as the accuracy given. There are so many things that can manipulate birth weight that are environmental...too many ways to collect data that are not taken in to account... I have one thing you all of you to think about...Take the runt out of a flush because he is a smaller frame size....feed him like you are feeding the larger framed bulls in the flush...what do you get? In my opinion from observations over the last 40 years....shorten them up in length, you raise the rea.... pick the runt and you raise the imf sooner..... pick smaller and smaller frames out of a cow family with historically larger frames you decrease the pelvic and increase the calving problems.....picking bull for herdsires with smaller frames then historically normal you are picking from the ones that are from the group that are less then normal... What if one rancher uses the pencil to collect birth, weaning and yearling weights? Say he is 10# light on actual birth....50# heavy on weaning and #150 heavy on yearling. What does that do to EPD's? Doug Hoff once made a statement in his sale catalog about EPD's.... I am looking for it so I can post it here. [/QUOTE]
