Maize grain (corn) — proximate composition (Feedipedia)
Source: Feedipedia (INRAE/FAO open ingredient database), page "Maize grain | Feedipedia" (/node/556). First-hand web text extracted (tags stripped) to pdf-raw/feedipedia/ingredient_maize_grain.txt; composition values are verbatim from the page's proximate ("Main analysis") table. Units as published (% as fed / % DM / MJ/kg DM / g/kg DM). Avg/SD/Min/Max/Nb columns preserved.
