Production controls shall include analysis sufficient to adequately monitor quality.
3. (c) Selenium shall be incorporated into complete feed by adding no less than one (1) pound of a premix containing no more than 272.4 milligrams (600 ppm) of added selenium per pound.

4. (d) Commercial feeds containing more than 0.3 parts per million (ppm) added selenium shall include the following on the label:

   1. (1) A guaranteed analysis statement for the minimum and the maximum parts per million (ppm) of selenium.

   2. (2) Feeding and/or mixing instructions that bear adequate directions for the safe and permitted use of a feed containing added selenium, including the maximum permitted levels of use for a specific species. Maximum permitted use levels per species include:

      1. (A) In complete feed for chickens, turkeys, swine, sheep, beef cattle, dairy cattle, ducks, horses, goats, llamas, alpacas and bison not to exceed 0.3 part per million.
      2. (B) Feed supplements for limit feeding for beef cattle, bison, and horses at a level not to exceed an intake of three (3) milligrams per head per day.
      3. (C) Feed supplements for limit feeding for sheep, goats, llamas, and alpacas at a level not to exceed an intake of 0.7 milligrams per head per day.
      4. (D) Salt-mineral mixtures for free-choice feeding of beef cattle, bison, and horses up to 120 parts per million in a mixture for free-choice feeding at a rate not to exceed an intake of three (3) milligrams per head per day.
      5. (E) Salt-mineral mixtures for free-choice feeding for sheep, goats, llamas, and alpacas up to 90 parts per million in a mixture for free-choice feeding at a rate not to exceed an intake of 0.7 milligrams per head per day.
   3. (3) The statement “Caution: Follow label directions: Feeding added selenium at levels in excess of 0.3 ppm in the total diet is prohibited.” Selenium premixes for the further manufacture of feed may use the statement “Caution: Follow label directions. The addition to feed of higher levels of this premix containing selenium is not permitted.”
