Raven is correct that program and similar cost share programs have made an impact on seed stock sales. It is voluntary, I have bought and sold ( in different years and programs as in the same one is considered a conflict of interest) both as a result of the programs. I know some that are very much opposed, although not many around here seem to be. The way I see it, the program is there and available if someone chooses not to participate then the money is still there and someone else will use it so I figure I may as well throw my hat in the ring so to speak if I can benefit from it. I doubt that very many folks would deny a sale of a bull or female around here because someone is buying with cost share funds.
I would venture to say that the farms grazing capacities, infrastructure, and cattle quality have greatly improved over the years as a result in large part to these programs.
On a side note, if it is still the same as years past, Angus bull CED's are required to be 7 or higher for heifer acceptable, not sure about any other breeds CED's though.
