The steers used in this fattening trial were part of a larger group used
in a wintering trial reported on page 46 of Kansas Circular 358. At the
beginning of the fattening period the ration was gradually changed from
a high roughage, wintering type, to a high energy, fattening type. Also
at that time five of the steers in the stilbestrol lot were reimplanted
with 24 mgs. of diethylstilbestrol and five steers in the synovex lot were
reimplanted with synovex. Individual calves remained in the same
experimental group as during the wintering study but the groups were
moved from the outdoor lots to concrete lots in which shelter was available.
