Feed Categories or Types #172
Comments
FAO also has a list of "feed materials for ruminant species" (see http://www.fao.org/fileadmin/user_upload/gleam/docs/GLEAM_2.0_Model_description.pdf) table 3.2. Number Material Description |
Feed type : Enum --> ? feed distribution type, feed group type, feed class type, feed category |
This issue is solved in the next release, definitions are added to develop |
I've been looking for a set of feed types or categories (not individual feed names) that we could use for the feed types enumeration mentioned in #93.
https://www.feedipedia.org/content/feeds has a set of categories, but these relate to the type of plant (or other source) used to generate the feed. In their example, maize grain and maize green forage would be in the same category.
In 1980 the International Network of Feed Information Centers (INFIC or IFN, coordinated by USAID) put together a Feedbase specification for which there is an old PDF online (Harris et al). Their feed classes were:
They also define a vast amount of feed attributes (properties). A number of later papers and articles
ICAR has a Feed and Gas working group https://www.icar.org/index.php/technical-bodies/working-groups/working-groupsfeed-and-gas/ but all the papers I have found standardise inputs to a Dry Matter equivalent, without discussing coding or representation of different feed types.
The Bar Diamond (USA) Feed Classification **System uses the 8 IFN classes above, plus another based on Roughage, Concentrate, Supplement, and another to designate Nitrogenous, Fibrous, Lipid, Mineralized, Carbohydrate. Finally they identify whether the protein source is mainly Animal, Milk, Plant, Microbial, Non-protein Nitrogen, Fecal, or Mixed.
The Finnish feed tables at https://portal.mtt.fi/portal/page/portal/Rehutaulukot/feed_tables_english/feed_tables/ruminants use a Group including:
NZ Farm Data Standards have a two-level categorisation system, of which the top level is most helpful:
DairyOne (USA) uses the following categories for labs and analytics:
