Juveniles under the 4F/4D regime showed compensatory growth and reached the same
body mass of control juveniles (i.e. complete catch-up growth) at the end of the experiment. This physiological
response was not affected by the two high-protein diets tested, and it may be at least partly explained by an improved
food conversion ratio, a similar ability to digest and absorb nutrients and an increased efficiency in protein
digestion with respect to control juveniles.
