[QUOTE="alexfarms, post: 628305, member: 8677"] The original reason I made this post was because 2008 was the first calf crop that I had ever completely split my inbreds off from my outcross cattle, beginning at the birth wieght point. i had done some splitting in the past for different pastures and feed conditions and on some ww, but never completely from birth. I had some really small birthweight calves in 2008, due to several possiblities. One of my inbred heifers came back with yearling epds higher than that of her parents average and it caught my eye. I noticed she had a bw ratio of 125%, and I thought I must had entered the data wrong. No. She had an 85# bw that the analysis adjusted down...down?...1# and it ratioed at 125. This raised her yw epd 10# above the average of her parents. I hadn't expected bw alone to affect yw epd that much. All of my heifers had an average adjusted bw of 82#. This tells me the inbreds need to be entered completely separate from the outcross calves. This will raise the bw epds on my inbreds, so that is not exactly doing them a favor. But I'll bet it is going to be more accurate in the long run. Time will tell. [/QUOTE]
