We only have one daughter of Black Granite. We bought her from SAV. She is out of SAV Madame Pride 5290. Daughter of 0075. She has had one calf so far, but took more tries to AI than most of our other heifers. Her first calf by Charlo was average. She is starting to look a little better flesh wise. I think it has taken her a bit to adjust to our environment. We calve at 7000' in elevation with a few feet of snow in the winter.( over 120" snowfall annually)
She did breed back on time to President.
Based on the foot score EPD, 7229 can throw some feet issues, hopefully Black Granite will be better.
If looking for a Son of 7229, I'd go with Mill Bar Hickok.
I'd try Jet Black also, not sure if he's available right now though.
