EFFECTS OF SOYBEAN MEAL ON INTESTINAL MORPHOLOGY OF ATLANTIC SALMON (SALMO SALAR L)

摘要

Soybean meal (SBM) can induce enteritis in the distal intestine of Atlantic salmon (Salmo salar L.) but the exact appearance of this condition is still unclear. The current changes in the enterocytes structure are described as deep shortening of the simple and complex mucosal folds, decreasing number of the supranuclear vacuoles (SNV) in absorptive cells, widening of the central stroma with high amount of connective tissue, an increasing infiltration of inflammatory cells in the lamina propria and anincreased formation of microvillar vesicles (Van Den Ingh et al., 1991; Baeverfjord and Krogdahl 1996; Buddington et al. 1997; Krogdahl et al., 2000). The present study assesses the effects of SBM doses on the kinetics of the enteritis process.
