[QUOTE="Aaron, post: 1221578, member: 1682"] If the calves are put together right (smooth and long), and the cows have some pelvic size, no reason that they can't easily handle 100 lb calf. Heifers I don't really want over 90 lbs, but they can do 100 lbs if they have to. I don't want small 60-70 lb calves because they are more easily stressed in adverse weather conditions and eventually you will (some say it's BS) breed a herd of cows that will only be able to calve unassisted to that range of birthweights - seen a lot of good herds screwed up that way. My birthweights are much lower in the May-June calving season than 15 years ago in Feb-March calving , where less than 100 lbs was like 10% of the calves. Lots of 105-114lbs. Didn't have an extraordinary amount of pulls back then either - cows were built right. I was including both cows and heifers in that original number, but if I split them up, problems occur with between 0-2% of cows and about 0-4% of heifers, with most years being around 2-3% on the heifers with 80-90 lb calves.
