USE OF ESTROGENS OR ANTIANGROGENS OR ESTROGENS IN COMBINATION WITH ANTIANGROGENS FOR REVERSAL OF MALE SEXUAL PHENOTYPE IN POULTRY

摘要

Fertilized poultry embryos are treated with estrogens or antiandrogens or estrogens in combination with antiandrogens during a period of embryonic development when the gonads are bipotential. This treatment causes genetic males to exhibit a female phenotype. When sex reversed male birds are crossed with normal male birds all offspring will be genotypically male.
