Ingredient List
57.265 Ammonium Chloride
is the product resulting from the neutralization of hydrochloric acid with ammonia generally expressed as NH4Cl. It must contain not less than 25.6% nitrogen (equivalent to 160% crude protein). It must contain not more than 0.1% moisture, 0.4% salt (NaCl), 15 ppm iron (Fe), 3 ppm arsenic (As), and 10 ppm heavy metals reported as lead. It may be treated with not more than 1.0% tricalcium phosphate to prevent caking. It shall not be made from by-product ammonia recovered from coke oven gas. It is
57.27 Ammonium Sulfate
is the product resulting from the neutralization of sulfuric acid with ammonia. It shall contain not less than 21% nitrogen (N) and not less than 24% sulfur (S). It shall contain not more than 75 ppm arsenic (As) and 30 ppm heavy metals reported as lead. This does not include ammonium sulfate made from by-product ammonia recovered from coke-oven gas. It shall be used only in ruminant feeds as a source of sulfur and nitrogen in an amount that supplies not more than 2% of equivalent crude protein
57.154 Basic Copper Chloride
is the copper salt of hydrochloric acid and hydrated form of copper oxide generally expressed as Cu2(OH)3Cl and its hydrated forms. Minimum copper (Cu) must be specified. (Proposed 1995, Published 1997)
57.1 Bone Ash
is the ash obtained by burning bones with free access to air, and containing a minimum of 15.3% phosphorus (P). The label must show a guarantee for calcium (Ca) and phosphorus (P). (Published 1935, Amended 1952)
57.2 Bone Charcoal
is obtained by charring bones in closed retorts. It must contain a minimum of 14% phosphorus (P). It must be labeled with guarantees for calcium (Ca)
57.17 Bone Charcoal, Spent
is the product resulting from the repeated charring of bone charcoal after use in clarifying sugar solutions. It must contain a minimum of 11.5% phosphorus (P). It must be labeled with guarantees for phosphorus (P) and calcium (Ca). (This product is sometimes referred to as “Spent Bone Black,” however, spent bone charcoal must be used in all labeling.) (Published 1938, Amended 1952, 1963)
57.14 Bone Phosphate
is the residue of bones that have been treated first in a hydrochloric acid solution and thereafter precipitated with lime and dried. It must contain a minimum of 17% phosphorus (P). It must be labeled with guarantees for calcium (Ca) and phosphorus (P). (Proposed 1952, Amended 1963, 1997)
57.3 Calcite
is an acceptable source of calcium carbonate. It must be true to name and contain not less than 33% calcium (Ca). (Published 1952)
57.10 Calcium Carbonate
is a product true to name which contains a minimum of 38% calcium (Ca). (Published 1946, Amended 1963) Reg. 582.5191.
57.7 Calcium Carbonate, Precipitated
is an acceptable source of calcium carbonate. It must be true to name and contain not less than 33% calcium (Ca). Precipitated calcium carbonate must be used in all labeling. (Published 1952)
57.51 Calcium Chloride
is the calcium salt of hydrochloric acid generally expressed as CaCl2 and its hydrated forms. Minimum calcium (Ca) and chlorine (Cl) must be specified. (Published 1975)
