Impact/Purpose:
To evaluate the occurrence of 17a- and 17B-trenbolone, both of which are synthetic androgens present in animal wastes
Description:
Little is known concerning the potential ecological effects of hormonally-active substances associated with discharges from animal feeding operations. Trenbolone acetate is a synthetic anabolic steroid that is widely used in beef production to promote growth in the US. - - -The purpose of this study was to evaluate the occurrence of 17a- and 17B-trenbolone, both of which are stable in animal wastes and are relatively potent androgens in fish and mammals. Further work is needed to ascetain the degree to which synthetic androgens such as trenbolone contribute to androgenic activity of feedlot discharges.
