I saw Heat Seeker at about a week of age. He was not a large calf by any means, certainly no where near 140 pounds. I would have guessed him in the 80 pound range. ASA shows his birth EPD at 1.0 while Heat Wave's is 3.5. I had 2 Heat Seeker calves quite a few years ago out of Shorthorn cows and they were small at birth. I would guess both in the upper 70's. They were nice heifers, but a little high spirited for me. That's a polite way of saying they were nuts. I have not used Heat Wave, only his sire, so I have no first hand experience with Wave. I would add, though, that most of the discussion on his mother is immaterial. Those who want to use him will, regardless of what anyone says, and those who choose not to use him won't. As usual, both groups will either laugh at the other or shake their heads in disbelief.
