[QUOTE="Margonme, post: 1396552, member: 25776"] This is not "face measuring" but I have the pelvis of heifers I retain and sell measured. A caliper device is inserted into the rectum to get the height and width of the birth canal. The measurements are in centimeters. The two measurements are multiplied to arrive at a square centimeter number. As a rule, you want the measurement to be about 160 square centimeters at yearling. Regarding selecting those that calve easy - that is what EPDs attempt to do. [/QUOTE]
