Analysis methods and significance of rodent fence steroid

Animal fecal steroid level is an important indicator to detect physiological status of animals. The plasma determination method can make animals produce stress reaction during the collection of samples, and this method can affect the accuracy of determinable result. Compared with the plasma determination method, as a noninvasive method, the fecal steroid hormone detection technology has many advantages, including avoiding the anthropogenic interference to animals, easily to collect samples, and more accurate and reliable determination results. This paper summarized the domestic and foreign researches on determination of fecal steroid hormone in animals related to the samples collection and preservation, and analysis methods, and its important significance in the study of rodents, which could provide a reference for relevant research.
