[QUOTE="Lucky_P, post: 847004, member: 12607"] Sounds most like a 'genetics' problem - and the physical size of the bull is not the issue - it's the genetics behind the bull, the heifers, or both. Not all Angus bulls are 'calving ease' sires - some sire high birthweights or conformations that don't lend themselves to the calves being delivered easily. (Conversely, there are some relatively high-BW epd bulls that have decent calving ease, due to the fact that their calves are long and slender, rather than thick and blocky) The heifers also contribute to the equation; if they have the genetics for high birthweights, and/or small/narrow pelvic canals, even when bred to a low-BW epd sire, you may get excessively large calves - or heifers with small/narrow pelvic canals that don't lend them to easy delivery of anything but the tiniest, most slender of calves. Good thing that you're finally getting a veterinarian involved - I don't know that I'd have waited 'til I had that many dead calves to call for some professional help. [/QUOTE]
