Abstract
Dromostanolone propionate has been found to result in a surprisingly large increase in weight in animals when administered as a pellet implant. In female animals, e.g. heifers, estrus is also suppressed. A particularly effective implant pellet exhibits a substantially constant rate of drug delivery over a first time period and an abrupt termination of drug delivery at the end of said time period, thus eliminating the need to surgically remove the implanted pellet to stop administration of the drug to the animal.
