There is an important difference between the two comparisons.

SC1: Rice has PROTEIN OF HIGHER QUALITY...
Here, of higher quality is AN ADJECTIVE modifying protein, serving to compare ONE TYPE OF PROTEIN to ANOTHER TYPE OF PROTEIN.
OA: Rice has PROTEIN of higher quality than THAT in wheat.
Here, that is standing in for protein.
Implied comparison:
Rice has PROTEIN [that is] of higher quality than the protein in wheat [is of high quality].

SC2: Wild animals HAVE LESS total fat...
Here, less is an ADVERB modifying have, serving to compare how wild animals HAVE total fat to how other types of animals HAVE total fat.
OA: Wild animals HAVE less total fat than livestock fed on grain.
Implied comparison:
Wild animals HAVE less total fat than livestock fed on grain [HAVE total fat].
The words in brackets are omitted, but their presence is implied.

C: Wild animals have less total fat than that of livestock fed on grain.
Here, that is standing in for total fat.
