The code of federal regulations specifies how much selenium
may be added to feed. Veterinarians are not allowed to exceed these amounts in
feed, even with a prescription.
ODA recommends manufacturers occasionally check selenium
levels in feeds for species sensitive to selenium as well as updating
formulation system ingredient mineral values as needed. The actual selenium
level should be within 25% of the tag guarantee.
Bovine spongiform encephalopathy (BSE or mad cow disease)
To prevent the establishment and amplification of BSE
through feed in the United States, the Food and Drug Administration (FDA)

Anyone who either sells mixed animal feeds or ingredients or buys feed that may
be fed to cattle, sheep, or other ruminants has obligations under FDA rule.
