I don't see semen availabity listed on that page of the website, but it's not listed on some other bulls either, and I know semen is available on them. These guys work with Allied Genetic Resources or ORIgen, so my guess it would be through one of those distributors if it's available. You could call or email Jared...his contact info is at the bottom of that page, and he's good to get back to you with whatever informTion he has.
I'm not familiar with those other bulls or with any American bulls really. I ran across this guy just checking out Jared's other bulls, and his photo jumped out at me. I thought he was the most impressive bull he had pictured, and I raised one of the other ones! When I saw him on video, I immediately thought about your heifer. I think he's really cool. If I was breeding anything like that, I would definitely try him.
Good luck!
