[QUOTE="Jeanne - Simme Valley, post: 815823, member: 968"] Pretty much all measured traits sort of go hand in hand. The super calving ease bulls tended to give you SMALL calves, which grew into small heifers, which size for size, have smaller pelvic areas. Now, with the use of EPD's, we have isolated "spread" bulls - easy calving bulls with great growth traits. So, if you use a CE bull with some decent growth, you shouldn't run into reducing pelvic size. For a while, Universities were promoting measuring pelvics & keeping the largest pelvic measured heifers. They then realized that by doing that, producers were ending up increasing the frame size of their herd. "Normal" skelital (sp?) measurements go "hand in hand". Long spine, long leg bones, long pelvic bones. Trying to find the "outlyers" is the trick. So, yes, if you keep stacking CE bulls (without great growth traits) you will end up with smaller heifers with smaller pelvic size. [/QUOTE]
