Animal Feed Descriptions or Names

Table 1 International Feed Description: Origin (Examples)

With Specific Origin
genus Bos Gadus Trifolium Triticum
species Taurus Morrhua Pratense Aestivum
Level 1 generic name Cattle Fish Clover Wheat
Level 2 breed or kind Hereford Cod Red Winter
Level 3 strain - - - Delmar
With Non Specific Origin
Level 1 generic name Animal Grass Poultry Meadow plants
Level 2 breed or kind - - - -
Level 3 strain - - - -

The above are examples of feeds with specific origins. Some feeds may have no specific origin, and are described by their common name; e.g., animal, grass, poultry, meadow grass.

Minerals, drugs and chemicals are listed according to the nomenclature of CRC (1968). The chemical formula are designated where applicable.

Examples of International Feed Descriptions or Names with parts are given in Table 2.

breed or kind Hereford Cod Red Winter

Facet 3: Process (es) and Treatment (s). Many processes may be used in the preparation of a feed for consumption and some of these may significantly alter their nutritional value. Heat may damage some nutrients and, conversely, it may make others nutritionally more available. Pelleting increases consumption while grinding may affect digestibility of protein and carbohydrates.

It is important, then, that a feeder be aware of the processes to which a feed has been subjected. Also, the type of animal and its physiology must be considered relative to these factors. Therefore, origin and part terms are followed by those distinguishing the different methods of processing which are used alone or combined; such as separating, reducing size or thermal. The term dehydrated (descriptor: DEHY) when applied to AERIAL PART means feeds which are artificially dried. Similarly, FAN AIR DRIED indicates the AERIAL PART (hay) dried indoors by air convection.

The term, mechanically extracted (MECH EXTD) has been used rather than expeller extracted, hydraulic extracted, or old process.

part Milk Whole or cuttings Aerial part Grain
process Boiled Mech Extd Dehy Ground Ensiled Ground

Examples of International Feed Descriptions with processes are given in Table 3.

Facet 4: Stage of Maturity or Development. Although stage of maturity may be unimportant or may not even apply to many feeds such as grain by-products, it is probably the most important factor influencing the nutritive value of forages. There is an optimal stage of maturity for forage crops beyond which lignification or the reduction of the ratio of leaf to stem greatly reduces digestibility. Examples of International Feed Descriptions with stage of maturity for plants and animals are given in Table 4.

Facet 5: Cutting. Many forage crops are cut and harvested several times during the year. Each cutting has a unique nutrient content as well as characteristic physical properties. The descriptor for cutting refers to the sequence of cutting from the first to the last during the year (cut 1, cut 2, etc.). The maturity terms refer to stage of growth or of regrowth and, therefore, must be considered within the limits of cutting.

In tropical and subtropical areas, crops may be cut throughout the year, particularly if they are irrigated.

Table 4 International Feed Description: Origin + Fart + Process + Maturity + Cut (Examples)
genus Gallus Gadus Trifolium Digitaria
species Domesticus Morrhua Pratense Decumbens
generic name Chicken Fish Clover Pangolagrass
breed or kind Leghorn Cod Red -
strain - - - -
part Whole Whole Aerial part Aerial part
process Fresh Boiled Dehy Ensiled
maturity Day old - Early bloom 28-42 days' growth
cut - - Cut 1 Cut 2

The time to start counting cuttings for non-irrigated forages would be the first rainy season. For irrigated forages, the count should start from the first crop.

Since stage of maturity is more important than cutting data, the various cuts for forages are sometimes combined with the stage of maturity when data are summarized for feed composition tables. Examples of International Feed Descriptions with cuttings are given in Table 5.

Facet 6: Grade. Some commercial feeds and feed ingredients are given official grades on the basis of their composition and other quality characteristics. Such feeds are sold on a quality description basis in accordance with their official gradings. Thus, these grades and quality designations must be included as a definitive component in the description of the feed. These guarantees for various attributes are expressed in terms of "MORE THAN" (minimum) and "LESS THAN" (maximum) of some percentage of crude fibre, protein, fat, etc. LOW GOSSYPOL is an example of a quality grade. These guarantees and quality are used as descriptors in this facet. Examples of International Feed Descript
