Feed classification used in GLEAM 3.0.
Source
Not traced to any GLEAM document (whep#881). Searched and ruled
out: the GLEAM 3.0 Supplement S1 workbook (no sheet holds it); FAO. 2022.
Model Description, Version 3.0, Table 3.1/3.3 (ruminants, 27 feed
materials grouped as Roughages / Cereals / By-products / Concentrates,
pp. 32-37) and Table 3.5 (monogastrics, 42 materials grouped as Swill and
scavenging / Locally-produced / Non-local, p. 45); and Tables 3.2, 3.3
and 3.14 of the Version 2.0 Revision 5 description. None of those
groupings is the six-way Grass / Crop residues / Concentrates / Fodder
crops / Processed feeds / Animal products split shipped here, and
"Animal products - Milk, fish meal" has no counterpart in GLEAM's
ruminant material list at all. Treat the classification as a WHEP-local
convenience taxonomy, not a GLEAM table. No function in R/ reads it.
