抄録

The nutritional quality of test diets composed mainly of soybean, corn gluten and squid meals was evaluated in rainbow trout averaging 13g. A fish meal-based diet (43% protein, 14% fat) and three isonitrogenous test diets with a high fat content (21%) were prepared. Two of the test diets were supplemented either with essential amino acids (EAA) or bovine bile salts (BS) . The growth parameters were similar in all treatments. Although feed efficiency was higher in the test diet groups, the efficiency for the diet without supplemental EAA and BS was lower than the supplemented diets. Whole body crude protein content of fish fed with the EAA supplemented diet was higher than fish fed with the other test diets. There was little effect of feeding the test diets on the measured biological and biochemical parameters of blood, biliary bile, liver and intestine. A partial histological abnormality was observed in the distal intestine of fish fed with the test diets without BS while no such abnormality was found in fish fed with the BS supplemented diet. These findings indicate that diets containing soybean, corn gluten and squid meals support identical growth to the fish meal-based diet in rainbow trout. To attain more efficient utilization of dietary protein and normal intestinal histology, supplementation of EAA and BS to the diet is recommended.
