Retention of Injected Testosterone in the Meat of Adult Ewes1

E. F. Johnston, Frank Hudson, Ralph Bogart and John Kaufmes

Oregon State College2

Abstract

Meat from control and testosterone treated ewes was fed to four-week-old cockerel chicks to determine whether there was any residual testosterone in the meat as evidenced by increases in chick weight and comb size.

There were no significant differences in body weight and comb length increases, but the increase in comb height was significantly greater for chicks fed meat from control ewes. These results indicate that there was no residual testosterone present in the meat of ewes 4 days after treatments ceased.
