An experiment was conducted at the Lajas Agricultural Experiment Substation to determine the effect of injectable testosterone propionate on growing fattening barrows. The intramuscular injection at weaning time of 50 mg. of testosterone propionate into each ham caused no significant difference in rate of gain, final weight, feed efficiency, loin-eye area, backfat thickness and dressing percentage. It thus is concluded that a single intramuscular dose of 100 mg. of testosterone propionate at weaning time does not cause any significant effect on growth and carcass characteristics of fattening barrows. The possible effect of repeated dosages of testosterone propionate at different intervals in fattening barrows was not determined.
