[QUOTE="Northern Rancher, post: 815826, member: 5898"] We measured pelvic openings for years and who'd a thunk it but the heifers with the bigger pelvics had bigger calves and as much or more calving trouble than the smaller ones. All our cows and heifers calve out on pasture-I don't like to go over 80 pound bulls on the heifers or 90 on the cows-as far as EPD's try to keep breed average or lower-there's been a couple thousand calves born out there and were under .5% assist rate on both heifers and cows. I'd rather calve a herd with low BW stacked in it than the opposite. When setting up a heifer A"I program on a group of big BW heifers you have to be pretty cautious of the bulls you reccommend.
