摘要
Fertilized poultry embryos are treated with fowl antimullerian hormone which may function as an aromatase inhibitor and may also have a trophic effect on developing gonads. Fertilized poultry embryos are also treated with steroid biosynthesis inhibitors or antagonists which prevents the conversion of androgens to estrogens, and anti-mullerian hormone (AMH). By blocking the production of estrogens and enhancing the gonads the genotypic female is converted into a phenotypic male. The phenotypic conversion of females to males gives the treated birds the advantage of male growth characteristics. A single administration of the combination prior to about day 9 of embryonic incubation results in an irreversible change in sexual phenotype which results in enhanced weight gain and feed efficiency.
