The administration of sex hormones to ruminants, swine, and poultry increases the growth rate and efficiency significantly. Hormones are implanted subcutane- ously for slow release or given by mixing with the feed (page 421). Diethylstilbestrol is used quite extensively in animal and poultry hus- bandry. This hormone presumably induces the tranquilization of the male without castration. TESTICULAR HORMONES. Hormoues produced by testicular tissues are known as androgens. They are also present in urine. Although they.
