Abstract: Naturally occurring sex steroid hormones, such as androstenedione, testosterone (T), 17β estradiol (E2), to name a few, are found in water downstream from dairy operations. These hormones, together with other environmental contaminants including chemicals and pharmaceuticals, that can mimic, antagonize, or alter normal endocrine function are called endocrine disrupting chemicals. In this project, we wish to 1) survey commercial broiler litter to determine the presence and concentrations of E2 and T; and 2) determine the course of appearance of E2 and T in excreta of growing broiler chickens.
