A REVIEW OF STUDIES OF TRENBOLONE Issue 10 ACETATE USE IN BEEF CATTLE October 1990

چکیده
Trenbolone acetate (TBA), the active compound in Finaplix implants, is a synthetic steroid that is used for promotion of growth of beef cattle. By itself, TBA exerts only moderate effects on growth, performance and carcass characteristics of steers and heifers. When used in combination with estrogen(E)-containing implants, TBA results in dramatically increased growth, improved feed conversion efficiency and enhanced muscle deposition. The TBA+E combination is the most potent muscle growth promotant available to cattle feeders. There are reports of reduced quality grade, increased aggressiveness and sexual behavior, difficult hide pulling and other problems associated with use of TBA+E. This paper contains a review of data from TBA experiments as well as suggestions for use of TBA-containing implants in beef cattle growing and finishing systems.

Effect of growth promotants on the occurrence of endogenous and synthetic steroid hormones on feedlot soils and in runoff from beef cattle feeding operations.
Supplements and growth promotants containing steroid hormones are routinely administered to beef cattle to improve feeding efficiency, reduce behavioral problems, and enhance production. As a result, beef cattle manure will contain both synthetic steroids as well as a range of endogenous steroids including androgens, estrogens, and progestogens. A two-year controlled study was conducted in whic...
متن کاملIdentification of Metabolites of Trenbolone Acetate in Androgenic Runoff from a Beef Feedlot
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 the United States to promote growth of beef cattle. Metabolites of trenbolone acetate include the stereoisomers 17alpha- and 17beta-trenbolone, both of which are stable in ...
متن کاملProduct-to-parent reversion of trenbolone: unrecognized risks for endocrine disruption.
Trenbolone acetate (TBA) is a high-value steroidal growth promoter often administered to beef cattle, whose metabolites are potent endocrine-disrupting compounds. We performed laboratory and field phototransformation experiments to assess the fate of TBA metabolites and their photoproducts. Unexpectedly, we observed that the rapid photohydration of TBA metabolites is reversible under conditions...
متن کاملComparison of alternative beef production systems based on forage finishing or grain-forage diets with or without growth promotants: 1. Feedlot performance, carcass quality, and production costs.
Forty Angus-cross steers were used to evaluate 5 beef cattle management regimens for their effect on growth performance, carcass characteristics, and cost of production. A 98-d growing phase was incorporated using grass silage with or without growth promotants (trenbolone acetate + estradiol implants, and monensin in the feed) or soybean meal. Dietary treatments in the finishing phase were deve...
متن کاملEffect of repeated administration of combination trenbolone acetate and estradiol implants on growth, carcass traits, and beef quality of long-fed Holstein steers.
Our objective was to determine the effect of repeated use of implants on feedlot performance and carcass characteristics of Holstein cattle. Holstein steers (n = 128) weighing an average of 211 kg were blocked by weight and randomly assigned to 16 pens. At the start of the trial (d 0), pens were assigned to one of four treatments: 1) nonimplanted control (C); 2) implant on d 0, 112, and 224 (T3...
