Özet

The present study aimed to evaluate the possible effects of a natural hepatomodulator on growth; some biological, blood, and color parameters; body; cost analysis; and liver histology of rainbow trout. A commercial rainbow trout diet was used for the control group, and 500 mg kg(-1) of commercial additive was used for the treatment group. The experiment was carried out for 12 weeks. At the end of the experiment, there was no significant effect on growth or biological and some blood parameters (P > 0.05); however, significant skin brightness changes (P < .05) were observed on the fish. Also, liver sections of the fish fed with the control diet showed a high proportion of lipid accumulation on hepatic parenchyma compared to fish that were fed treated diets. These results showed that application of commercial artichoke extract to rainbow trout diets might have positive effects on outer skin colorization and liver fat accumulation.
