Abstract
Feeding in animal production is a challenge that farmers face in the search of the ideal animal weight in the least amount of time and at the lower cost. An experiment was designed to evaluate two hormonal stimulants, Phenylpropionate Nandrolone and Boldenone Undecylenate combined with a supply of mineral mix nutrition block and honey grass on Brahman steers compared with a check which was the normal farmer´s management. Statistical analysis was performed using a completely randomized design. Variables evaluated were weight gain, cinch increase and height at withers. The best treatment in terms of the three evaluated parameters was the one which used injectable synthetic anabolic Fenilpropionato Nandrolona, while the check only produced marginal gains. Financial analysis determined that the same treatment promoted the best cost-profit of $ 1.112
