After reading this thread, I thought I would measure our two show heifers since I was getting health work done at the vets anyway.
These are both 10 months old and sired by Moto Moto and are Fullblood Galloway heifer calves. They weigh about 750 lbs. They both came out at 196 square cm. One was 14 X 14 and the other was 13.5 X 14.5. They had actual BW of 70 and 72 lbs.
I was very happy with those results.
