Equations are of the form: measurement=aM_{b}^{b}, where M_{b} is body mass in kg.
CL, confidence limits for the scaling exponent, b.
MAPD, mean absolute percent deviation of measured values from the fitted relationship.
All anatomical measurements are defined in Materials and methods.
GT/RMC = ratio of greater trochanter height to radius and metacarpus length.
All measurements are in m (GT/RMC in m/m).
Relationships are given both excluding and including data for horses 18-21.
