Urinary steroid evaluations to monitor ovarian function in exotic ungulates: X. Pregnancy diagnosis in Perissodactyla
Abstract 10.1002/zoo.1430130205.abs Enzymeimmunoassays (EIAs) for estrone conjugates (EC), pregnanediol-3-glucuronide (PDG), and C-19 and C-21 progesterone metabolites (C-19/C-21) were used to analyze urine samples from four nondomestic equid species, four tapir species, and two rhinoceros species in an attempt to identify if these assays could be used for diagnosing and monitoring pregnancy. The same urine samples […]
An automated assay for fecal estrogen conjugates in the determination of sex in avian species
Abstract 10.1002/zoo.1430100410.abs Recently captive propagation of psitticines has become necessary in order to preserve and breed endangered species. As habitat destruction increases and importation restrictions become more stringent, the need for a reliable and noninvasive technique for sex assignment is essential to improve the productivity of breeding and raising birds in captivity. One aspect of […]
The use of long acting subcutaneous levonorgestrel (LNG) gel depot as an effective contraceptive option for cotton-top tamarins (Saguinus oedipus)
Cotton-top tamarins (Saguinus oedipus) are a critically endangered species that have been bred successfully in captivity for many years. For two decades, the Cotton-top Tamarin SSP© has been challenged with a high rate of reproduction combined with a history of contraceptive failures and nonrecommended births using the current Depo Provera® (medroxyprogesterone acetate) injection followed by […]
