English to German Science Livestock / Animal Husbandry animal feed

From the formulation data of a certain type of animal feed; the term appears several times in a table of amino acids. The table has the different acids in the rows and the columns are labelled as follows (three columns, each split into two sub-columns):

Content:
G/kg "As is"
% of protein

Poultry:
Digest % TRU
Digest g/kg

Piglets:
Digest % SID
Digest g/kg


Since the text hasn't been written by a native speaker, do sou think it would be possible it's supposed to read digested g/kg?
Or does Aufschlussprodukt (https://de.wikipedia.org/wiki/Aufschluss_(Chemie)) make any sense here? My chemistry isn't too great, especially when it comes to animal feed...
