I'm kind of excited about him. I plan to test for TH and DS in the near future but i dont have any TH or PHA carrier cows in my herd so im not hugely concerned. I AIed everything this year so he is strictly clean up. I do 7 day CIDR timed AI then turn the bull loose 2 weeks later. Last year all calves (10) were born in a 4 week window. Shorthorn folks, what do you think of him?
