This is a progress report of the wintering phase of the third trial of
this experiment. The results of the other two tests are reported in Circular
308 and elsewhere in this publication. The test is designed to
study the level of protein supplementation most desirable for wintering
steer calves to be sold off summer grass as stocker or feeder yearlings.
Results of the experiment are measured by the combined winter and
summer performance of the steers.
