[QUOTE="Lucky_P, post: 1427571, member: 12607"] Long-term studies by the bovine repro folks shows that - on average - after age 7, bulls' fertility takes a precipitous drop. If you're doing a BSE prior to each breeding season to assess his fitness at that time, you'd be well-served, but not totally protected. Last one we had, we kept til he was 10... after the first couple of years, he was pretty much only doing cleanup behind AI... but he had great disposition, and his daughters were nice, and we're a commercial herd producing stocker calves, so the occasional sire/daughter or sire/granddaughter mating was no issue... until he turned out to be the apparent founder of the latest recognized Angus genetic defect... and we had daughters/granddaughters/great-granddaughters comprising well over half the herd... requiring a lot of testing to ferret out the 'carriers'...not to mention 9-10 dead calves over a 4-5 year period, and premature culling of their dams.
