Dose determination and efficacy of remotely delivered norgestomet implants on contraception of white-tailed deer

Abstract 10.1002/(SICI)1098-2361(1997)16:13.3.CO;2-W Management of overabundant wildlife populations using contraceptives is being considered with increasing frequency in many localities. A wide array of effective contraceptives is needed to meet a variety of management objectives. Therefore, we evaluated the synthetic progestin norgestomet for its efficacy and its minimum effective dose in free-ranging white-tailed deer (Odocoileus virginianus). We […]

Pregnancy diagnosis in the black rhinoceros (Diceros bicornis) by salivary hormone analysis

Abstract 10.1002/(SICI)1098-2361(1996)15:13.3.CO;2-L Saliva samples collected from 12 black rhinoceroses (Diceros bicornis) were analyzed for 20 alpha-hydroxyprogesterone-like and total estrogen immunoreactivity. Five nonpregnant, two conception, and nine pregnancy intervals were monitored. HPLC co-chromatography of immunoreactive free steroid components in saliva indicated that one of three immunoreactive progestin components eluted with 20 alpha-hydroxypreg-4-en-3-one, whereas the single major […]

Effects of chronic melengestrol acetate contraceptive treatment on perineal tumescence, body weight, and sociosexual behavior of hamadryas baboons (Papio hamadryas)

Abstract 10.1002/zoo.1430140306.abs Melengestrol acetate (MGA) subcutaneous implants were used in seven adult female Hamadryas baboons to study the effects of chronic progestin administration on perineal swelling, behavior, and weight gain. At the dose level used (≥8 mg/kg body weight), cycles of perineal tumescence ceased and swellings subsided. Social dynamics were not significantly altered during treatment, […]
