The reason we like bulls that throw lighter weight calves 75-80 lbs, had a cow calve today that was 14 days late. Calf is 100 plus pounds. Same bull and cow year before last and the calf was 75 pounds one day early. A combination of a strage winter, weatherwise, and a very late calf can surely cause a train wreck. Took him a while to get up but he's eating and doing dandy, following mom around and trying to snare another teat.
