Status of Selenium and Other Essential & Toxic Elements in Oregon Grazing Sheep The findings improve our understanding of sheep mineral status in the region and highlight simple, cost-effective approaches to enhance routine mineral surveillance, allowing for earlier intervention and improved flock health Open Full Report
Effect of Different Selenium Supplementation Practices in Oregon on Whole-Blood Selenium Concentrations, Naturally Acquired Parasite Infections, and Inflammatory Mediators of Subclinical Inflammation in Ewes Background The focus of our selenium (Se) research is to improve health, prevent diseases, and increase productivity in sheep flocks across Oregon, where soils are deficient in Se. Deficiencies in the Se…
Oregon State University Research: Does feeding Spent Hemp Biomass affect Reproductive Health of Male Sheep? Summary of findings: Industrial hemp is a rapidly proliferating commodity since hemp was removed from the Controlled Substances Act.

Oregon State University Research: Follicle Stimulating hormone receptors are expressed in ewe’s tissues Abstract Follicle stimulating hormone receptors (FSHR) are present in granulosa cells, Sertoli cells, and other sites within the reproductive tract (uterine tube, uterus, placenta, and cervix). They are also present in many nonreproductive tissues (skin and adipose tissue, bone and cartilage, thyroid…
Oregon State University Research on the effects of PG-600® on ovulations, pregnancy and lambing rates Abstract Our objective was to evaluate reproductive effects of varying gonadotropin dosages on anestrous ewes pretreated with progesterone and then exposed to a novel ram. Hypothesis was that a lower dosage of P.G. 600® (equine chorionic gonadotropin 80 IU/ml and…
OSU Extension research in Selenium Supplementation Strategies for Livestock in Oregon selenium (Se) is an essential trace mineral for livestock. Selenium deficiencies have been described in many species, including cattle, sheep, goats, horses, swine, white-tailed deer, and elk. Clinical Se deficiency can cause nutritional myodegeneration, also known as white muscle disease. White muscle disease was…
