The ovarian cycles of 48 culled dairy cows were monitored by assaying plasma progesterone concentrations. Twenty-four cows received a subcutaneous implant of 300 mg trenbolone acetate at the beginning of the study. Of the implanted cows, two were pregnant, and six continued to cycle although their peak progesterone concentrations were significantly lower than in control cows (5.65 +or- 0.71 compared with 8.19 +or- 0.47 ng/ml).
