[QUOTE="Ky hills, post: 1506452, member: 24816"] I very much agree a reasonable CED and a lower + BW is what I like to see in a heifer bull. I have used bulls with as much as +2.5 BW and been ok, but am more comfortable with +2 or lower especially if they are bred heifers we are selling. I think there may be situations where the real low ones might be ok, but I have often wondered that at what point do those extremes just become numbers with no added benefits. I wonder if wide spread and continual use of low birth weight bulls could account for a higher rate of smaller pelvic measurements. We purchase heifers to breed and this year 6 didn't meet the required measurement of 150 cm. At first I thought that maybe they were all as a group a little younger perhaps, but then most of the ones that passed far exceeded the requirements being 190-220+ cm. and the group is as consistent in size as in the past.
