Selenium (Se) is an essential micronutrient for humans and animals, playing an important role in antioxidant function, thyroid hormone metabolism, reproduction and immune responses. Dr Sheena Fagan and Dr Richard Murphy of Alltech discuss how one must consider the individual digestibilities of selenium products to appreciate the differences that exist in terms of their bioavailability and bioefficacy for efficient animal production.
