This catalog provides a list of 20 common livestock feedstuffs with their metabolizable energy, total digestible nutrients, crude protein, neutral-detergent fiber, and ether-extract values on a 100% dry-matter basis. The data is sourced from the USDA ARS Feed Composition Database and NRC nutrient-requirement publications.
From the catalog README (verbatim): sourced from the USDA ARS Feed Composition Database and the NRC nutrient-requirement series — described there as “both public-domain government/standards data in keeping with the repo's PD/CC0 sourcing ethos.” US federal government works are public domain: free to use and free to not credit — we cite anyway to prove attribution is not required.
This catalog is a hardcoded educational reference table in OnlyCSharp.Data. The project embeds no per-row source links or license metadata; the references above are the catalog's own consulted-source citations, reproduced verbatim from its README. Factual values (names, numbers, classifications) are not copyrightable and no text is reproduced from these references. Per the repo's SOURCING ethos we cite every source; this catalog is flagged for per-source license links to be added in the Data lane.
