Frame Scores

The following tables give current estimates of cattle height, along with adjustment equations for bulls and heifers. Values for steers are not available; however, bull height estimates may be used as approximations for steers.

  Bulls: (-11.548+(0.4878*HIP HEIGHT))-(0.0289*DAYS OF AGE)+(0.00001947*(DAYS OF AGE*DAYS OF AGE))+(0.0000334*HIP HEIGHT*DAYS OF AGE) *The following equations only apply to hip heights taken when the animal is between the ages of 5 and 21 months.
