International Feed Description

An international feed description is composed of the previously described six facets and descriptors within the facets. The feed descriptions are maintained in an "International Feed Description Name File".

A six-digit "International Feed Number" (IFN) is assigned to each feed description. The first digit of this IFN denotes the class of feed. This reference number is used in computer programmes to identify the feed for use in calculating diets, summarization of the data, for printing feed composition tables and for retrieving on-line data for calculating diets for maximum profit.

A complete International Feed Description consists of all descriptors applicable to that feed. It is numerically identified by the IFN. This is illustrated by examples in Table 7.

Short Feed Names
Short names are used for Feed Composition Tables, compiled for use in particular countries or regions, when it is inconvenient to use the longer and more precise International Feed Description; however, the Short dame cannot be used for describing a feed when adding material to the feed data bank.
