Abstract
I conducted 2 fertility control experiments to test the efficacy of a gonadotropin releasing hormone (GnRH) agonist as a contraception method, and prostaglandin F2? (PGF2? ) as a contragestation method, in captive white-tailed deer (Odocoileus virginianus) does. My research with 12 mg GnRH agonist found that maximum efficacy was reached in does treated during October with subcutaneous implants, where efficacy was 100% the first year (n=7) and 25% the second year (n=4). Both May implant and October biobullet treatments were 100% effective the first year, but 0% effective the second year. Finally, applying treatme nts in May did not hinder the does current pregnancies from being carried full- term. My research with 25 mg PGF2? found that the biobullet treatment was 33% effective in the first mid- gestation (FMG) group (70-88 days of gestation) and 100% effective in the second mid- gestation (SMG) group (89-105 days of gestation).
