Diethylstilbestrol implant plus oral Chlortetracycline vs. Oral Chlortetracycline alone for fattening steers

Abstract

Hereford steers used in this study were fed in outdoor dirt lots without shelter. Each steer in lot 23, described in a trace-mineral study reported elsewhere in this publication, received a 24-mg. implant of diethylstilbestrol on the first day of the feeding period. Steers in both lots received 70 mgs. of oral chlortetracycline each day during the feeding period.
