[QUOTE="Ebenezer, post: 1531477, member: 24565"] My opinion and just that - numbers do not matter so much but rump shape in the cows does. Bonsma has an illustration of flat rump bone structure versus sloped rumps bone locations. Flat rumped (I assume ski slope rumps are worse) cattle in that diagram have the tail bone blocking part of the birth canal. (page 22 of the lecture reprint). To get the proper bone structure of the tail bone it also requires proper leg set, leg angles and works itself up to the spine- my opinion. Thus I want nothing swaybacked, post legged, anything that presents itself as abnormally long or has a ski sloped rump. Also, I think and Bonsma said that a cow should be her widest at the rear. Some dislike the parallel that a bull should be widest at the shoulders but not in the sense of either meatless or hard calving as some will always send up as a trial balloons to express dislike. Find a picture of the great old bull Emulous Bob of K Pride - he was 5.5" wider at his shoulders than at his rump. I'd love to have some of those cattle again. But I do watch and have known to avoid a herd(s) where their bulls consistently show -CED when used beyond their herd. I'm guessing pelvic problems or poor calf shape - I don't know but do not want to pull calves. [/QUOTE]
