Seller has always paid for the BSE on any bull I've purchased although I'm sure that's already figured into the price. I hit the jackpot with the breeder of my most recent bulls. Not only is he one of the nicest people you'll meet, he took the time to go through all my previous bulls registrations and hand select the bulls that would work best for my operation. No charge for delivery. Guarantees his bulls for the first year. One of my bulls got struck by lightning, had him less than a month & hadn't even turned him out. The breeder replaced him and when I gave him a check he refused. Clearly an act of nature has nothing to do with fertility (or libido) but he stood by his guarantee. Plus, if I don't like him or his calves I can switch him out next year (the one that was struck was a heifer bull, the replacement is not).
