Involvement of Taste Receptors in the Oro-Sensory Perception of Nutrients in Rainbow Trout (Oncorhynchus mykiss) Fed Diets with Different Fatty Acid Profiles

Table 3

Mean values (± SEM) of growth performance, feed parameters and digestive energy intake of rainbow trout fed with different diets for 30 days before the preference trial. Values are expressed as group mean ± SEM; One-way ANOVA, Tukey post hoc; Different lower case letters indicate significant differences (P < 0.05) among diets.
