Our Jersey cow has always had registered Jersey calves. She needs to be bred back and I have considered having her AI'd with Guernsey semen. Since this will be her 5th or 6th calf, she's a very large Jersey and she has never had problems, would this be considered safe to do? I know that Guernseys are larger. I assume that would be a good mix as I've seen that a few seem to produce that cross on purpose. Thoughts? Not even sure if my AI Tech carries Guernsey. They don't seem that common around here.
