An investigation of blood selenium values of goats in the Northeast
Selenium (Se) toxicosis has been acknowledged long before selenium deficiency was recognized. Supplementation of feeds with selenium is especially important in regions of the world with low soil selenium, such as the Eastern regions of the U.S. Various soil and crop factors such as plant species, soil pH, and altitude can influence the relative selenium content in feeds. Reference ranges for some trace minerals are not available for goats. In many instances, the values are borrowed or extrapolated from other species. Recent investigations demonstrate that extrapolation is not an accurate means of determining reference ranges. Still, much of the work being done with selenium and small ruminants seems to focus on sheep. The purpose of this investigation is to establish a relative reference range for blood selenium in goats of varying age, production purpose, and dietary nutrient composition in the northeastern United States.
