Angus X Shorthorn question

I have a question for all you shorhorn breeders out there in SP world. If any of you have bred your shorthorn cows/ heifers to a pb angus bull have you gotten any off color calves? By off color I am not refering to blues, blacks or blacks with some white but rather a non standard shorthorn or angus color?

The reason for the question is that we have run an angus bull for clean-up on the shorty cows for the last 6 years and have always gotten blacks or blues. Last year we had to buy a new clean up bull and bought another pb angus, thus far the two shorthorn cows that have calved to him both have had calves that can only be desicribed as brown ( almost brown swissish) color. Not red of any color and not black. Bulls reg papers do not show he is a red carrier or that anything in his lineage was a red carrier. I am courious if this bull might have a little unspoken something in his pedigree.

In the not so recent past, it was not uncommon to get those brownish colored calves from chi and chi cross bulls. I have also been told that some of that chi blood has accidently slipped into some regestered angus cattle. I have even seen registered angus bulls sire scurred calves. Immagine that.

Similar thing happened to us. We went to an Angus production sale and bought a bull that would work for our operation and happened to be the highest performing bull he was a Vermillion Dateline son.  First calf crop awesome with no problems.  Second calf crop had 1 with horns, 1 with scurs, and two that were so off colored it wasn't even funny.  One looked like a holstein and one was the color of a deer and they were out of solid red and black double-polled cows.  Now i know the scurs could happen with the simmi but very unlikely but i dont think we should have ever gotten horns and to date those cows had never thrown anything but solid black calves from any of our other simmy or angus bulls, needless to say the owner was speechless when we told him and said that he had never had anyone else complain about that kind of stuff and to this day i still don't think the guy believed us.

Just got back in from checking all of the calves out the this bull...we noticed the last Angus cow to calve to him has an off colored calf as well. Fawn colored is probably a good way to describe. This calf not only is not black, she also has a white spot on the side of her neck about the size of a quarter. Guess we have a few things to check in to!!

Sounds like your bull has a little something else in his pedigree.
