"Polled Hereford" is the breed. They are those red beef cattle with white heads/feet/tail tips and no horns.

THE POLLED HEREFORD STORY
(soon to be a major motion picture)

The original Hereford breed had horns. The guy who created the Polled Hereford breed wanted Herefords with no horns; he sent letters to every registered Hereford owner "polling" them as to whether they had any Herefords without horns. From this effort he found 173 (IIRC) hornless Herefords, and these were the foundation of the Polled Hereford breed.

Note: That's not exactly what online sources state, but it's the way it was told to me.
