different foods habits. Species were Phyllotis darwini (omnivorous) and Octodon degus
(herbivorous). The activity of sucrase, maltase and aminopeptidase-N were determined in
vitro in animals feeding two contrasting diets. No effect of dietary chemistry on sucrase and
maltase activities was observed. Nevertheless, aminopeptidase-N showed a reversible
response to diet in P. darwini but not in O. degus. Through Principal Component Analysis we …
