This document provides an interpretation on the forms of feed that may appear on livestock feed labels. The information is complementary to the Chapter 4.0 General guidance on labelling.

Livestock feed forms Interpretation
Beads Same definition as prills.
Block- tub Agglomerated feed compressed into a solid mass cohesive enough to hold its form, weighing over 1 kilogram and generally weighing 15 – 25 kilograms. Sometimes fed in a tub or a tank format.
Brick Agglomerated feed, other than pellets, compressed into a solid mass cohesive enough to hold its form and weighing less than 1 kilogram.
Cake The mass resulting from the pressing of seeds, meat, or fish to remove oils, fats, or other liquids.
Colloid
(1 to 1000 nanometers)
A colloid is a mixture that has particles ranging between 1 and 1000 nanometers in diameter that can remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container.
Crumbles – Crumbs Pelleted feed reduce to granular form
Cube Agglomerated feed formed by compacting and forcing through die openings by a mechanical process. The density may vary depending on the particle size and length of the ingredients.
Dry Generally, moisture is less than 15%
Flakes An ingredient rolled or cut into flat pieces with or without prior steam conditioning.
Gel A solid or semi-solid substance produced by mixing a gelling agent(s) with broth or water, and/or approved livestock feed ingredients.
Liquid Nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure.
Mash A mixture of ingredients in meal form.
Meal An ingredient that has been reduced in particle size by grinding or another means.
Paste A thick, soft, moist substance typically produced by mixing dry ingredients with a liquid.
Pellet Agglomerated feed formed by compacting and forcing through die openings by a mechanical process. The density may vary depending on the particle size and length of the ingredients.
Powder Pulverizing a feed or feed ingredient into fine or very small particle size or atomization and drying of liquids.
Prills A granule or small bead formed by the solidification of droplets of a liquid or molten material falling against an upward air stream.
Scratch Whole, cracked, or coarsely cut grains.
Slurry A slurry is a mixture of insoluble solids denser than water suspended in liquid, usually water.
Suspension A heterogeneous mixture in which the solute particles do not dissolve but are suspended throughout the bulk of the solvent, floating around freely in the medium and will eventually settle.
Syrup Concentrated juice of a fruit or plant.
Textured Containing fine materials in a pelleted form, mixed with coarser ingredients.
Wafers A form of agglomerated feed based on fibrous ingredients in which the finished form usually has a diameter or cross-section measurement greater than its length.
