Correlation between serum and fecal concentrations of reproductive steroids throughout gestation in goats
(ELSEVIER SCIENCE BV, 2008)
Non-invasive techniques such as the measurement of fecal steroids are now widely used to monitor reproductive hormones in captive and free-ranging wild-life. These methods offer great advantages and deserve to be used in ...
Non-homogeneous distribution of steroids in fecal pellets: An example in brown brocket deer (Mazama gouazoubira) with progesterone metabolites
(2019-10-01)
Measuring reproductive hormones in feces has become an important tool in the endocrine characterization of wild animals’ reproduction. However, several factors may influence its success, such as fecal collection and storage ...
Tracking the Ovarian Cycle in Black-and-Gold Howlers (Alouatta caraya) by Measuring Fecal Steroids and Observing Vaginal Bleeding
(SPRINGER, 2011)
A better understanding of a species` reproductive physiology can help conservation programs to manage primates in the wild and develop assisted reproductive technologies in captivity. We investigated whether measurements ...
Monitoring ovarian cycles, pregnancy and post-partum in captive marsh deer (Blastocerus dichotomus) by measuring fecal steroids
(Oxford Univ Press, 2018-01-25)
The marsh deer is an endangered species from the marshlands of central South America. This study aimed to characterize certain aspects of the reproductive physiology of marsh deer hinds, including the duration and fecal ...
Distribution of sewage input in marine sediments around a maritime Antarctic research station indicated by molecular geochemical indicators
(ELSEVIER SCIENCE BV, 2010)
Sediments from Admiralty Bay, Antarctica were collected during the austral summers of 2002/2003 and 2003/2004 in order to assess the distribution and concentration of sewage indicators originating from Comandante Ferraz ...
Characterization of seasonal reproduction patterns in female pichis Zaedyus pichiy (Xenarthra: Dasypodidae) estimated by fecal sex steroid metabolites and ovarian histology
(Elsevier Science, 2009-12)
Reproductive strategies vary considerably among species, but most studies have focused on a very limited number of mammalian species. Knowledge of the reproductive cycle and behavior is essential for developing and ...
Fecal Progestins Differentiate Pregnant From Nonpregnant Early Luteal Bitches
(W B Saunders Co-Elsevier Inc, 2021-06)
Considering the high perimplantation progesterone (P4) secretion that occurs in female domestic dogs, we hypothesize that fecal P4 concentrations distinguishes pregnant from nonpregnant early luteal bitches. The objective ...
Validation of a radioimmunoassay for measuring fecal cortisol metabolites in the hystricomorph rodent, Octodon degus.
(2009)
Determination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many ...
Avaliação da fidedignidade dos ensaios de esteróides fecais realizados no Laboratório de Medidas Hormonais do Departamento de Fisiologia da UFRN
(Publica, 2006)
Neste estudo foi avaliada a confiabilidade das técnicas de extração fecal e dosagem do cortisol, progesterona e andrógenos de Callithrix jacchus cujas concentrações são mensuradas por ensaio imunoenzimático (ELISA). A ...
