Description
Summary:[EN] This study investigated the effects of the incorporation of barley instead of wheat to study fish growth and biometrics parameters, body composition, retention efficiency and liver histology of rainbow trout Oncorhynchus mykiss. Experimental diets were used containing different barley concentrations (0-16%) randomly assigned to four groups per treatment. Results showed a significant change on liver histological parameters. Liver cell vacuolization was significantly lower on fish fed with 16B diets compared to control diet and revealed some degeneration. Those fish also showed more regular hepatocytes than in control diet.
