Validation of an enzyme immunoassay for measurement of excreted estrogen and testosterone metabolites in the white-crowned sparrow (Zonotrichia leucophrys oriantha)
Abstract 10.1002/zoo.1430140203.abs Over the past few years there has been a growing interest in hormonal analyses, despite the cost and difficulty involved in measuring hormones using radioimmunoassays. Therefore, there is a need for alternate procedures, such as enzyme immunoassays, capable of providing similar data to that provided by radioactive methods. Enzyme immunoassays are a less […]
Differences in Fecal Androgen Patterns of Breeding and Nonbreeding Kori Bustards (Ardeotis kori)
To better understand breeding conditions to promote reproduction in captive kori bustards, fundamental endocrine studies measuring fecal androgen metabolites in male and female kori bustards were conducted. Feces collected weekly from males and females were analyzed for testosterone using enzyme-linked immunoassay. Results from adult males (n = 5), adult females (n = 10), immature males […]
