In my situation, using him on crossbred cows, I am assuming I won't have to worry about any problems right?
you will create what are called ladies in waiting. they are waiting for a carrier bull. then boom, people will typically blame the bull, but he's 50% of the problem, no if's and's or but's. carriers are only for people who will test ALL offspring and are looking for something in particular and will then breed out the defect, the rest, go to slaughter.
of course you are the perfect target for unscrupulous breeders who won't reveal the status of their animals and will try and sell semen/individuals at pre-test prices and individuals at pre-test prices.
if you don't understand recessive defects and aren't willing to test every animal that isn't terminal, don't EVER use a carrier.
