How many bulls in the past have supposedy been the greatest thing to have ever been on the ground and then some "injury" makes semen scarce and "valuable"?
Grand dad would say something not so very nice and it would probably be just about on target, there is something haywire and semen is not the problem. A genetic hickey, or like so many of these clubby bulls, the offspring ain't worth hauling to town and if they are it's kinda like selling 1/2 blood longhorns, you sell them before anyone can tell what they are.
I've got one, not bad but far from great and being out of a so so cow may have saved him. I'm thinking this ain't nothing but a promotional scam.
