[QUOTE="TCRanch, post: 1528290, member: 24027"] JMJ, the following is quoted by Lucky P from an older thread. The pelvic bones - and in particular, the pubic symphysis(the ventral suture where the pelvic bones come together), fuse/ossify at around 27 months of age. So...if you can manage to get a heifer bred to calve before 27 months, there's a little more 'wiggle room' available for a little larger calf or less likelihood of dystocia, due to the extra amount of 'give' available - and once the unfused pelvis is 'stretched out' by delivery of a calf, it doesn't quite 'go back to its previous size' - pelvic area remains a bit larger from then on. But, after 27 months of age, those bones will have fused, and there's just less space available. So...if you've got an older, fatter heifer with fused pelvic bones, you may encounter increased incidence of dystocia. [/QUOTE]
