Soybean Meal for Salmon
Soybean meal in the diet of the Atlantic salmon, Salmo salar L., causes an inflammatory response in the distal intestine. A study was designed using immunohistochemical markers and various enzymes to characterize the cellular morphological and biochemical changes in the intestinal mucosa of salmons fed a fish meal-based, or a diet where thirty percent of the fish meal was replaced with soybean meal. Results indicated that the fish fed the soybean meal diet had reduced enzyme activity in the distal intestinal epithelial cells. The mid-intestine showed little response to the diet. These results suggest that a toxic/antigenic component contained in the soybean meal diet may reduce nutrient digestibilities previously reported for salmon fed soybean meal.
