[QUOTE="redcowsrule33, post: 927329, member: 8629"] I always thought the opposite. However, statistics have proven us both wrong. I can't get the link to work for me, but if you google "steerplanet selection for calf shape" you can find the article. Quote from the article: "In conclusion, you are probably not wrong when you swear a certain calf was born with difficulty because he has wide hips or broad shoulders. Nevertheless, those big hips or shoulders probably just means that he was big. The sire’s calving ease and birth weight EPDs provide a more accurate estimate of a calf’s chance for an unassisted birth than any body shape measure. Reliable prediction depends upon consistent, repeatable trends. [b][i]This does not mean that a long, skinny, 95-pound calf will never be born unassisted while a seemingly square-block-shaped 75-pound calf has to be pulled. What it does mean is that, on average, progress cannot be made in decreasing calving difficulty by selecting for body shape in addition to birth weight.[/i][/b]" Can I find plenty of examples of high-accuracy bulls that have a low birthweight EPD and poor calving ease? Sure. But on a statistical basis they are the exception. [/QUOTE]
