The US Food and Drug Administration?s (FDA) Center for Veterinary Medicine (CVM) is responsible for regulations relating to the safety of feed intended for animals (including but not limited to horses, cattle, swine, poultry, and fish), under the Animal Feed Safety System (AFSS). The regulations control many aspects of the production, storage, and labeling of animal feed, and the permitted levels of additives and contaminants, such as potentially toxic heavy metals.  aSelenium  aSelênio  aAnimal feeds  aSelenium supplemented1 aALINE FERNANDES DE OLIVEIRA1 aLandero, J.1 aNOGUEIRA, A.
