Abricot was very hard to handle in the stud, that is true, but he was not the only bull that was in this category. There were several bulls of a few breeds that had to be watched very closely. I cannot remember which bulls kills stud workers but I do remember that ABS had a stud near Calgary back in the 70s and two workers there were killed by bulls. I can't remember what bulls were responsible.
I remember watching Abricot being collected at Alta one time. They had a small JD tractor with a cab, that they backed up to the door of his pen. Abricot had two rings in his nose and they hooked a good sized logging chain into the nose rings and attached the chain to the back of the tractor. They then opened his gate and everyone left the building. The guy on the tractor led him to the collection site and they collected the semen and led him back to his pen. It was quite an ordeal to watch.
I used Abricot a lot back in that day, when we had our Simmental herd. I never had any issues with his progeny and I liked them. He was a bigger framed Simmental bull but he did have some body to him as well. He was not built like a dairy bull.
I bet your heifer develops into an outstanding female! In regards to the Simmental X Shorthorn cross, I worked at Bar 5 Simmental at Douglas, MB for several weeks prior to their March sales for about 8 years and I remember them telling me that their best cow families, outside their full blood cows, all were developed from using Simmental bulls on Shorthorn cows.
