0.39. Likewise the mid and posterior regions of the body show varia¬ 
tions, the rear flank with a coefficient of variation of 8.7 ±0.48, circumfer¬ 
ence of rear flank 6±0.34, width of loin 7.5±0.43, width of thurls 5.9± 
0.34, circumference of paunch ii ± o .62, and distance of hip to buttock 
5.2 ±0.29. 
The measurements affected most by growth show the least variations 
and include the distance of shoulder point, rear flank, and withers from 
the ground, length of head, and distance of shoulder point to buttock. 
In general, Table VII shows the greatest variation in those regions 
of the body which change most in a fattening steer and those regions 
affected most by deposition of fat and development of muscular tissue.
