My first Shorthorn heifer was out of a Leggs 21 cow. She was the first Ar Su Lu Kool daughter sold. She was so small that I don't believe she was big enough pelvicly to have the 80 lb Eskimo Joe bull calf that we pulled out of her. Long story short, She was a show champion at several fairs, very clubby and hairy. Her first calf by Eskimo Joe, a steer, sold for over $3,000. Unfortunately, her next calf was breech and we took her to OSU. They said she was scarred from the first calf and would not be able to give normal birth on her own. We then flushed her to a TH free sire fearing that she may have TH and the tests were not available yet. She ended up having TH and PHA. The bull we flushed her to also had PHA and there was no test at the time we put the eggs in. Well, we all know how this story ends and it isn't good. Dead calf, dead recip, and our first Shorthorn purchase heading to the sale barn. <rock>
With all that said, I can't honestly say from experience whether the small pelvic area causing the scarring was a genetic trait from the sire or the dam's side. My other Kool daughter has done well. Anyone with daughters from Legs 21 see this as a potential problem?
