(a) General Provision: The following general provisions apply to animal products:

(b) Meat Meal is the dry rendered product from mammal tissues, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents, except in such amounts as may occur unavoidably in good manufacturing practices. It shall not contain added extraneous materials not provided for by this definition. The Calcium (Ca) level shall not exceed the actual level of Phosphorus (P) by more than 2.2 times. It shall not contain more than 12.0 percent Pepsin indigestible residue and not more than 9.0 percent of the crude protein in the product shall be pepsin indigestible. The label shall include guarantees for minimum crude protein, minimum crude fat, maximum crude fiber, minimum Phosphorus (P) and minimum and maximum Calcium (Ca).

(c) Meat and Bone Meal is the dry rendered product from mammal tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents, except in such amounts as may occur unavoidably in good manufacturing processing practices. It shall not contain added extraneous materials not provided for in this definition. It shall contain a minimum of 4.0 percent phosphorus (P) and the calcium (Ca) level shall not be more than 2.2 times the actual Phosphorus (P) level. It shall not contain more than 12.0 percent pepsin indigestible residue and not more than 9.0 percent of the crude protein in the product shall be pepsin indigestible. The label shall include guarantees for minimum crude protein, minimum crude fat, maximum crude fiber, minimum Phosphorus (P) and minimum and maximum Calcium (Ca).

(d) Blood Meal is produced from clean, fresh animal blood, exclusive of all extraneous materials such as hair, stomach belchings and urine, except as might occur unavoidably in good processing practices. The process used must be listed as a part of the product name such as conventional cooker dried, steamed or hydrolyzed.

(e) Poultry By-Product Meal consists of the ground, rendered, clean parts of the carcass of slaughtered poultry, such as necks, feet, undeveloped eggs, and intestines, exclusive of feathers, except in such amounts as might occur unavoidably in good processing practices. The label shall include guarantees for minimum crude protein, minimum crude fat, maximum crude fiber, minimum phosphorus (P), and minimum and maximum calcium (Ca). The Calcium (Ca) level shall not exceed the actual level of phosphorus (P) by more than 2.2 times.

(f) Poultry Hatchery By-Product is a mixture of egg shells, infertile and unhatched eggs, and culled chicks which have been cooked, dried, and ground, with or without removal of part of the fat.

(g) Hydrolyzed Poultry Feathers is the product resulting from the treatment under pressure of clean, undecomposed feathers from slaughtered poultry, free of additives and accelerators. Not less than 75.0 percent of its crude protein content shall be digestible by the pepsin digestibility method.

(h) Dry Rendered Tankage is a dry rendered product consisting of undecomposed whole animals, including hair, hoof, horn, hide, feathers, and viscera, with no additional hair, hoof, horn, hide, feathers, or viscera added.

(i) Dried Meat Solubles is obtained by drying the defatted water extract of the clean, wholesome parts of slaughtered animals prepared by steaming or hot water extraction. It shall be designated according to its crude protein content which shall be no less than 70.0 percent.

(j) Fleshings Hydrolysate is obtained by acid hydrolysis of the flesh from fresh or salted hides. It is defatted, strained, and neutralized. If evaporated to 50.0 percent solids, it shall be designated "Condensed Fleshings Hydrolysate". It shall have a minimum crude protein and maximum salt guarantee.

(k) Animal By-Product Meal is the rendered product from animal tissues, exclusive of any added hair, hoof, horn, hide trimmings, manure, stomach and rumen contents, except in such amounts as may occur unavoidably in good processing practices. It shall not contain added extraneous materials not provided for by this definition. This ingredient definition is intended to cover those individual rendered animal tissue products that cannot meet the criteria as set forth elsewhere in this section. This ingredient is not intended to be used to label a mixture of animal tissue products.

(l) Hydrolyzed Hair is a product prepared from clean, undecomposed hair, by heat and pressure to produce a product suitable for animal feeding. Not less than 80.0 percent of its crude protein shall be digestible by the pepsin digestibility method.

(m) Hydrolyzed Leather Meal is produced from leather scrap that is treated with steam for not less than 33 minutes at a pressure not less than 125 pounds per square inch and further processed to contain not more than 10.0 percent moisture, not less than 60.0 percent crude protein, not more than 6.0 percent crude fiber, not more than 2.75 percent chromium, and with not less than 80.0 percent of its crude protein digestible by the pepsin digestibility method. Hydrolyzed leather meal may be utilized in livestock feeds as provided in food additive regulation, Title 21 of the Code of Federal Regulations, CFR Part 573.540, April 1, 2001.

(n) Sprayed Dried Animal Blood is produced from clean, fresh animal blood, exclusive of all extraneous material such as hair, stomach belching, urine, except in such traces as might occur unavoidably in good factory practice. Moisture is removed from the blood by a low temperature evaporator under vacuum until it contains approximately 30.0 percent solids. It is then dried by spraying into a draft of warm, dry air which reduces the blood to finely divided particles with a maximum moisture of 8.0 percent and a minimum crude protein of 85.0 percent. It shall be designated according to its minimum water solubility.

(o) Egg Shell Meal is a mixture of egg shells, shell membranes and egg content obtained by drying the residue from an egg breaking plant in a dehydrator to an end product temperature of 180° Fahrenheit. It shall be designated according to its crude protein and calcium content.

(p) Egg Product is product obtained from egg graders, egg breakers and/or hatchery operations that is dehydrated, handled as liquid, or frozen. This product shall be free of shells or other non-egg materials except in such amounts which might occur unavoidably in good processing practices, and contain a maximum ash content of 6.0 percent on a dry matter basis.

(q) Poultry Meal is the dry rendered product from a combination of clean flesh and skin with or without accompanying bone, derived from the parts of whole carcasses of poultry or a combination thereof, exclusive of feathers, heads, feet, and entrails. It shall be suitable for use in animal food. If it bears a name descriptive of its kind, it shall correspond thereto.

(r) Blood Meal, Flash Dried is produced from clean, fresh animal blood, exclusive of all extraneous material such as hair, stomach belchings and urine except as might occur unavoidably in good manufacturing processes. A large portion of the moisture (water) is usually removed by a mechanical dewatering process or by condensing by cooking to a semi-solid state. The semi-solid blood mass is then transferred to a rapid drying facility where the more tightly bound water is rapidly removed. The minimum biological activity of lysine shall be 80.0 percent.

(s) Glandular Meal and Extracted Glandular Meal is obtained by drying liver and other glandular tissues from slaughtered mammals. When a significant portion of the water soluble material has been removed, it may be called Extracted Glandular Meal.

(t) Animal Plasma is the product obtained by spray drying plasma which has been separated away from the cellular matter (red and white blood cells) of fresh whole blood by chemical and mechanical processing. The protein portion of this product is primarily albumin, globulin, and fibrinogen type proteins. The minimum percent crude protein and the maximum percent ash shall be guaranteed on the label.

(u) Ensiled Paunch Product is a product composed of the contents of rumen of slaughtered cattle. The moisture level is reduced to 50.0-68.0 percent. The product is then packed into an airtight environment, such as a silo, where it undergoes an acid fermentation that retards spoilage. The ensiled product will have a pH of 4.0 or less.

(v) Leather Hydrolyzate is obtained from leather trimmings that are pressure cooked with the addition of steam and sodium hydroxide. Chromium is precipitated and separated so that not over 30 ppm (Solids Basis) remain in the hydrolyzate. This product can be used as a liquid ingredient or as a powder. In either event, the analysis on "as a solids basis" will not be less than 75.0 percent crude protein and not less than 85.0 percent of the protein shall be pepsin digestible.
