SINCE WE BEGAN RAISING CATTLE, WE HAVE MEASURED OUR CALVES CANNON BONE. WE DO THIS AT BIRTH. WE SIMPLY USE A MEASURING TAPE. HOLD THE BOTTOM OF THE TAPE ON THE DEW CLAW OF THE CALF, TAKE IT TO THE BEND IN THE CALF'S LEG. YOU WILL HAVE A MEASUREMENT BETWEEN 8" UP TO 10'' FOR THE MINIATURES.
  THIS MEASUREMENT WILL GIVE YOU A FAIRLY GOOD IDEA OF HOW BIG YOUR ADULT CATTLE WILL BE. THIS GIVES AN OPITION OF CUTTING THOSE BULLS CALVES EARLY. THE SMALLER THE NUMBER WILL BE THE SMALLER CATTLE AND ETC. ETC.
