title: [Urinary steroids in calves following administration of anabolic compounds. Effect of total diet].
abstract: Levels of testosterone, trenbolone, 17 beta-estradiol (conjugated plus unconjugated) and creatinine were measured in urine of calves treated 55 days before with trenbolone and 17 beta-estradiol implants. The mean concentration of urinary creatinine and implant steroids was increased by a factor 3 after 1 day of total diet and 5 after 2 days, levels of individual calves exhibiting a great dispersion.
