The highest IVPD was observed in the taxa of group 1, although
only a significant difference (P < 0.05) with the taxa in group 2 was
detected (Table 6). On the other hand, the results obtained for multiple
nutritional parameters in the three groups are shown in
Table 6. As described in paragraphs above, the most reliable nutritional
parameter is the protein-digestibility corrected amino acid
score (Sarwar, 1997; Schaafsma, 2005). Group 1 has the highest
values for this index (PDCAAS), distinguishing itself clearly
(P < 0.001) from the other two groups. Moreover, this group also
has the highest biological value BV (P < 0.001). With respect to
the theoretical PER, differences (P < 0.05) have only been found
in PER1, and group 2 has the highest score.
